       General Principles of 
      Erosion. - The physical features of a country are the result of agencies 
      that act upon the surface and in the underlying rock. The rain, with small 
      proportions of certain gases which it has washed out of the atmosphere, 
      causes the rock to decay. Frost aids the process by enlarging the openings 
      along joint planes and pore spaces thus increasing the exposed surface. 
      The decayed rock, in the form of clay, mud and coarser fragments, 
      accumulates upon a level country and even on slopes to form the soil. On 
      an inclined surface, however, the general tendency of this detrital 
      material is to move towards a lower level. The movement is brought about, 
      at first very largely by the rain wash; but the power of transportation 
      rapidly increases as the rain gathers into rills, and the rills join to 
      become brooks, and the brooks unite to form rivers. The finer material is 
      borne easily along, but the coarser fragments, rolled or pushed along the 
      bottom, are used by the stream to wear away the solid rock, and during the 
      journey downward are themselves worn into rounded sand and pebbles. In the 
      trunk stream and its tributaries and on the inter-stream areas as well, 
      the work of erosion goes on, the streams entrenching themselves more 
      deeply, the valleys widening through general denudation, the finer 
      material being carried far downward even to the sea and there deposited, 
      and the coarser either ground up fine or left somewhere along the stream 
      course. As rocks vary much in character, some being soft, others hard; 
      some easily decomposed, others more resistent; some flat-lying, others 
      tilted or folded; some bedded, others massive; the agencies acting upon 
      them produce various results that tend to increase the surface 
      irregularities and emphasize the physical features. Nature thus carves out 
      of the solid rock land forms -mountains, hills and ridges with intervening 
      valleys, ravines and gorges-while the debris is lodged on slopes, built 
      into flood plains and deltas, or deposited in the sea to reappear at some 
      subsequent period in the world's history as the solid rock of a new land 
      mass. 
      The work of the waves is 
      similar to that of the streams in that it more rapidly wears away the 
      softer and weaker rock, forming coves and bays, and leaves the harder and 
      stronger as outstanding capes and headlands. The tools used by the waves 
      are fragments of rock torn from the land; and they, as in the case of the 
      material in the stream-bed, become ground down and rounded and converted 
      into cobble-stones, gravel, sand and clay. 
      The combined action of streams and waves tends 
      to reduce the land area, and ultimately to bring it to the level or near 
      the level of the sea-to base-level or make of it what is known as a 
      peneplain. These geological processes are so slow as generally to escape 
      observation, but given sufficient time for the task, they will bring about 
      the final result - peneplanation. There are, however, two important 
      factors that may either hasten or retard this result. The relative 
      position of land and sea is not permanent. Sometimes the shore-line around 
      the land mass rises, at other times it sinks-the sea apparently receding 
      at one time and advancing at another. This elevation or subsidence has its 
      effect upon base-levelling. When the coast is raised, the streams and 
      waves have additional work set before them; when it subsides, the 
      strand-line is moved in over the land, the lower courses of the streams 
      are submerged and peneplanation is urged forward. 
       
      Topography.-The relationship between topographical features and underlying 
      rock is well illustrated in Cape Breton Island, the frame work of which 
      consists of an ancient mass of crystalline rock associated with 
      metamorphic types both of igneous and o f sedimentary origin. Overlying, 
      in many places, flanking or surrounding and extending seaward, are 
      formations of newer rock almost altogether sedimentaries. The physical 
      features naturally fall into two divisions, Highlands and Lowlands, 
      corresponding largely with these two different kinds of rock. A geological 
      map of the Island shows the larger river valleys floored along their lower 
      courses by the younger Carboniferous rock, -clear evidence that the 
      drainage of today was established in pre-Carboniferous time, and that, 
      during the Carboniferous period, at least the lowlands of the present were 
      covered by the sea. The Highlands, where extensive, have a comparatively 
      level summit, bare reek showing in places, and marshes, ponds, sluggish 
      streams and stunted shrubs appearing among timbered areas. Even where the 
      summit area is small this flat condition prevails, and the general 
      elevation is preserved. This level skyline is most noticeable from the 
      sea, or to one standing upon a prominence in the region, and it impels one 
      to the conclusion that this country was at some time in the far past 
      reduced to base-level. R. A. Daly calls the highlands a remnant of an 
      uplifted Cretaceous peneplain. If this be so, then, since the uplift, the 
      most of the streams have found, and now run in, their old 
      pre-Carboniferous channels. A recent subsidence has drowned the lower 
      courses of the rivers. 
      During the Great Ice Age, the Island was 
      glaciated. The evidence is found largely on the lowlands. The drift is not 
      abundant, nor are the glacial scratches found numerous; but, especially 
      along the western coast, the rock surface just above the reach of the 
      waves is smoothed and grooved by the ice action, and mounds of glacial 
      drift in places over a hundred feet thick are found. Here the ice movement 
      seems to have been towards the land, and elsewhere it followed the 
      depressions, its course being well northward in the eastern portion of the 
      Island. The erosion, 
      sedimentation, earth movements and glaciation for Cape Breton Island, as 
      described above, are applicable to Inverness County. The division into 
      highlands and lowlands strikingly applies. The county-line follows 
      somewhat closely the watershed through the northern tableland area except 
      where the North Aspy and Cheticamp are streams of some length where they 
      cross the line from opposite directions. In a similar manner, the divide 
      is followed south to Little Narrows. Thence the line runs westward along 
      the south shore of St. Patrick's Channel to Portage which it crosses to 
      the waters of the Great Bras D'Or, and follows the shore of the Lake to 
      the head of West Bay. From here, it is in a straight line with but one jog 
      to the head of Ship Harbour on the Strait of Canso. 
       
      The Inverness Highlands.-The northern part of the county is largely a 
      highland region with an average elevation of over a thousand feet-a 
      comparatively level area, broken by knobs, low hills and valleys that are 
      shallow except towards the margin of the tract where the larger streams 
      have entrenched themselves deeply and formed gorges and cascades. This 
      older land mass either presents a bold front to the sea, or is bordered by 
      a fringe of the lowlands. Southwards are areas with a slightly lower 
      elevation, but underlain by rock similar to that of the, north, and with 
      the same characteristic flatness of top. Such are the Mabou Highlands, 
      Creignish Hills, North Mountain of West Bay, the Mullach Bucklaw and Lake 
      Ainslie Hills, a large part of the country between Southwest Margaree and 
      Middle River, the Sugar Loaf of Margaree, and a large district between the 
      Upper North East Margaree, Forest Glen and the head waters of the upper 
      tributaries of Gallant River. Where the summit is of large extent on these 
      highlands, "barrens" occur on which rock outcrops appear in places with 
      the vegetation varying from moss and marsh grasses, through low shrubs 
      into stunted trees around the margin. 
      The Mabou Highlands have grassed hills, 
      parklands, and forested areas, and are high, steep, and imposing where 
      they face the waters of the Gulf. The Creignish Hills and North Mountains 
      are steepest towards the salt water bodies that front them. They and 
      isolated areas north of them have the general northeast-southwest trend 
      'characteristic of similar masses in the eastern part of the Island and 
      known as Appalachian structure. The Sugar Loaf is a picturesque hill with 
      grassy slopes overlooking the surrounding deeply trenched valley of the 
      Margaree in the west, the more open valley of the smaller streams on the 
      east, and the beautiful pass that joins these valleys. 
      Although local variations occur, there is a 
      marked similarity among -the rocks of these highlands. It is highly 
      probable that the isolated areas are connected underneath the younger 
      rock. It may be that in various parts of the county where hills of younger 
      rock have an elevation not much less than that of the older, a care of the 
      latter rock lies beneath the former. Salt Mountain and adjoining hills to 
      the eastward :along St. Patrick's Channel, hills stretching along from 
      Mabou to Margaree, Bald Mountain, Pleasant Bay, Bear's Hill at Cape St. 
      Lawrence and others may have such a structure. 
      Rocks of the Highlands. - Numerous 
      descriptions of the rocks from various localities of this old land mass 
      are to be found in the Reports of the Geological Survey of Canada. They 
      are the work, largely, of the late Hugh Fletcher, a careful observer, an 
      indefatigable worker, and a most likeable man. The term "Syenite" was used 
      by Fletcher in the old sense to designate a rock made up of quartz, feld-spar 
      and hornblende. In later usage, this is a hornblende-granite. More recent 
      workers in certain districts call Fletcher's "syenite" a granite. The rock 
      mass is in many places intricately mixed, the oldest being much 
      metamorphosed. Gneisses, schists and quartzites occur. There are also 
      volcanics such as felsites, quartz-felsites, porphyries and trap, some of 
      which is amygdaloidal. The grained rocks are granite, diorite and syenite. 
      The bulk of the rocks is of igneous origin; but some of them are, without 
      a doubt, altered sedimentaries. At or near the top of this complex mass, 
      either interbedded with the altered sedimentaries or in contact with the 
      igneous rock, is a series of crystalline limestones and dolomites-the 
      George River Limestone of Fletcher. It occurs in all the areas of old 
      rock, in widely scattered belts in the northern region, .but in the 
      Creignish Hills and the North Mountains there are numerous zones 
      especially around the margins of the old rock mass. In some places the 
      beds are thin; in others, a hundred feet or so in thickness. 
      All this rock, Fletcher called pre-Cambrian, 
      but left no record of relationship between the members of the group, other 
      than that of the George River Limestone. Recently, Mr. W. J. Wright, in a 
      published report on the geology of the Clyburn Valley, Ingonish, states 
      that the oldest formation there - the Clyburn - "was intruded by the 
      Ingonish gneiss, and the two were subjected to great deformational 
      processes before the intrusion of the Franey granite." Wright's Franey 
      Granite is the same rock as Fletcher's syenite. Many of Fletcher's 
      descriptions seem to fit Wright's interpretation of the structure in the 
      Clyburn Valley, and it may be that a similar succession obtains for the 
      whole massif. If so, the altered sedimentaries and volcanics are the 
      oldest, and were intruded by the gneisses, and, perhaps at a much later 
      time, both formations were intruded by the granite. 
      The hills, such as Salt Mountain, that are 
      made up of younger rock, with perhaps a core of the older, are in large 
      part Carboniferous sedimentaries. 
      The Lowlands. - The surface of the remainder 
      of the county consists of intervals, low plains, and dissected uplands. A 
      fringe of these lowlands extends along the coast from Creignish to 
      Cheticamp, with a break at Cape Mabou. In places, it is narrow; elsewhere, 
      it embraces the whole breadth of the county. North of Cheticamp, a second 
      and a third belt of the lowlands is encountered at the margin of the old 
      land. The drainage basins of all the larger streams-the Inhabitants, 
      Denis, Skye, Mabou, Broad Cove, Margaree - are largely in this lowland 
      region. Where, as in the case of the North East Margaree and the Cheticamp, 
      a large part of the drainage is in the highlands, the lowlands extend far 
      up among the hills. 
      Rocks of the Lowlands. - Forming a fringe along the shore from Creignish 
      to Hastings, and extending around the base of the Creignish hills towards 
      the north to beyond Queensville, is a belt of igneous and altered 
      sedimentary deposits, in places much contorted, which Fletcher called 
      Devonian. All the 
      remaining consolidated rocks belong to the Carboniferous System. The 
      lowest member consists of shales, sandstones, grits and conglomerates, in 
      places greatly, altered by intrusions of trap and of diorite. Elsewhere, 
      it is less altered and not associated with trap. This series is often 
      found flanking or surrounding an area of the older rock. Overlying this is 
      a series consisting of marine limestone, often oolitic, gypsum and 
      associated calcareous rocks, sandstone, etc. This occurs largely around 
      the coast, and in the valleys of the larger streams. Both these series are 
      Lower Carboniferous. 
      The Upper Carboniferous is represented by the Coal Measures and consists 
      of shales, sandstones, and interbedded seams of coal. An isolated area of 
      these rocks occurs at River Inhabitants. The main portion, however, 
      consists of a series of narrow areas along the coast from Judique to 
      Cheticamp. These are remnants of a once extensive basin which has been, to 
      a large degree, removed by the action of the sea. The beds have a seaward 
      dip, so that where coal occurs, as at Port Hood, Mabou, Inverness, St. 
      Rose and Chimney Corner, it extends under the waters of the Gulf. How far 
      seaward the coal beds, extend, or, in other words, what was the western 
      limit of the swamps in which flourished the vegetation that produced the 
      coal, it is not possible to say. On the low-lying portions around the 
      margin of the land mass as it was at that epoch in the world's history, 
      these swamps had their origin. How much more extensive the land was then 
      than it is& today is unknown, but it is significant that at various places 
      around the southern borders of the Gulf in the Maritime Provinces and in 
      Newfoundland, the coal measures occur. The land must have been subjected 
      to small oscillatory movements of elevation and depression in order that 
      one bed of coal should succeed another with intervening strata as they are 
      found today. Coal 
      Occurrences and Coal Resources.-Near the head waters of River Inhabitants, 
      about midway between Glendale and Big Brook, is• an area underlain by 
      rocks of the Coal Measures. The basin, in which coal is found, is of small 
      extent, approximately one square mile. The seams are thin, the largest 
      which is the uppermost, having a thickness of but one foot, eight inches, 
      and the beds of coal occur near the top of the series. Mr. D. B. Dowling, 
      [Coal Fields and Coal Resources of Canada. Geological Survey, Dept of 
      Mines, Ottawa Memoir No. 59.] of the Canadian Geological Survey,. gives 
      the "probable reserve" of this basin as 1,000,000 metric tons. [The metric 
      ton is equivalent to 2,204.6 pounds avoirdupois.] 
       
      At Port Hood, the coal-bearing strata run parallel to the shore for about 
      two miles with a low dip towards the sea, but as they continue southward 
      the dip increases until it becomes steep. This deformation has probably 
      caused the coal beds to curve westward towards the south.. These beds are 
      apparently broken by a fault somewhere between Smith Island and the 
      mainland, as rocks of Lower Carboniferous age appear in the cliffs of the 
      island. There are several small coal seams less than twenty inches in 
      thickness underlying the main seam which is seven feet thick. There is 
      said to be another seam higher up in the series outcropping beneath the 
      waters of the harbour. Considerable work was done on this area previous to 
      1878 when the mine was closed down. The main seam was a producer from 1899 
      to 1911 when the sea entered the mine and work had to be discontinued. In 
      1910, the production was 86, 847 tons. This seam has since been opened 
      further south, and last year (1920) produced 53,745 tons. The "probable 
      reserve" is placed by Dowling at 3,000,000 metric tons for a one foot seam 
      in a land area of three square miles, and 12,000,000 metric tons for a 
      submarine area of two square miles recoverable from a six-foot seam. 
       
      The Mabou coal area is a small field, much faulted, where several seams of 
      good thickness outcrop on Coal Mine and Finlay Points. There are seams 7 
      feet, 8 feet, 15 feet and 5 feet. The coal is submarine, dipping at a 
      somewhat steep angle seaward, but changing to a much easier one a few 
      hundred feet down the slope and probably flattening out at a small depth. 
      Coal was produced from this area for some years and taken over a railway 
      about six miles long to a shipping pier at Mabou Harbor. In 1903, the 
      production was 6,859 tons. The mine was flooded by the sea in 1909. 
      Dowling states that the "actual reserve" here is 12,000,000 metric tons; 
      the "probable reserve" 36,000,000; and he considers the latter a moderate 
      estimate. "At the 
      mouth of Broad Cove river, a narrow belt of coal measures, resting on 
      pre-Cambrian at the south and on Lower Carboniferous at the north, 
      contains several seams the exact a real distribution of which has not been 
      determined." Twelve seams are reported. Measurements made by Prof. H. Y. 
      Hind in 1873 gave six seams. The same beds measured later by Mr. Charles 
      Robb gave the following section: 
      1. A three-foot seam. 
      Intervening strata with a reported 5 foot seam....376 feet. 
       2. A seven-foot seam. 
      Intervening strata 437 feet. 
       3. A four-and-a-half-foot 
      seam. 
      Intervening strata 303 feet. 
       4. A three-foot seam.... 
      Intervening strata 32 feet 
       5. A three-foot-nine-inch 
      seam. Recent borings 
      seem to prove the presence of eight seams occuring as follows in 
      descending order [Communication from Mr. R. D: Anderson, until recently of 
      the Department of Public Works and Mines, Halifax.]: - 5 ft., 4 ft. 8 in., 
      6 ft., 7 ft. 2 in., 5 ft. 2 in., 7 ft., 5 ft., 10 ft. The main seam, No. 2 
      in Robb's section, has been a large producer since the completion of the 
      railroad to Port Hastings in 1900-'01 and its extension later to Point 
      Tupper. In 1913 this seam produced 327,613 tons; in 1920, the production 
      was 182,000 tons. Mining has extended beneath the sea about 3500 feet. In 
      the summer of 1920, work was begun on a new slope, the Henderson, to open 
      up a seam 1600 feet northeast of the No. 1 slope. This seam is 13 feet, 
      with 7 feet of clean coal in the upper part and with shale parting below. 
      At Port Ban, three miles south of Inverness 
      town, a seam containing over six feet of coal but with a shale parting of 
      2½ feet is in course of development From the measurements of Robb, Dowling 
      estimated the "actual reserve" at - marine, 86,000,000 metric tons; land, 
      28,800,000. The result of recent borings will very materially increase 
      this estimate. The 
      two areas further north known to be underlain by coal seams are St. Rose 
      and Chimney Corner "separated by about one and a half miles of unproved 
      territory." According to the report of Dr. A. O. Hayes (1918) the St. Rose 
      area appears to contain three seams of coal lying in a basin limited on 
      the west side by an unconformity or fault, or both, which causes the coal 
      to closely overlie the Lower Carboniferous gypsum at this side. "No. 1 
      seam is said to be about four feet thick. No. 2 contains five feet two 
      inches solid coal with only a quarter inch clay parting one foot eight 
      inches from the roof. No. 3 is reported to be six feet thick with two 
      four-inch partings." The gross tonnage of this area, Hayes estimated at 9, 
      500,000, or a recoverable total of 7,500,000. The Chimney Corner area 
      shows three workable seams in a section exposed across the strike in the 
      cove. Prof. Hind's measurements gave the following sections: 
      1. Thin seams, 1 foot 6 inches.  
      2. Strata about 300 feet.  
      3. Coal, 3 feet 
      4. Strata, 88 feet. 
      5.-Coal-main seam-five feet.  
      6. Strata, 200 feet.  
      7. Coal, 3 feet, 6 inches. 
      "The land area seems to be a shallow basin 
      with the western edge turned downwards towards the sea." Somewhat 
      extensive operations were carried on here between 1866 and 1873 on two 
      seams. In 1873, the surface buildings were destroyed by fire and the work 
      ceased, but has been intermittently carried on since then. Hayes estimated 
      the coal recoverable from this area as 6,000,000 tons. Dowling gives for 
      St. Rose and Chimney Corner "actual reserve," - land 21,000,000 metric 
      tons; "probable reserve'' - land, 18,000,000 tons; sea, 25,000,000. 
      The Coal Measures at Friar's Head and 
      Cheticamp Island as well as those of Margaree, Smith and Henry Islands, 
      are not known to contain coal. 
      The reserves of coal for Inverness County' as 
      given by Dowling are land areas-"actual," 61,800,000 - "probable," 
      22,000,000; submarine areas-"actual," 86,000,000 - "probable," 73,000,000 
      metric tons-altogether, 242,800,000 metric tons. An estimate made in 1914 
      by the Mines Department at Halifax placed the amount of coal in situ at 
      882,000,000 tons. Since that date, a much greater thickness of workable 
      coal has been proved by borings. 
      Limestone. - Limestone is abundant in the 
      George River Limestone series, which is found chiefly on the North 
      Mountain and Craignish Hills. At Marble Mountain, the crystalline 
      limestone is extensively quarried for the use of the Dominion Iron and 
      Steel Company as a flux in the production of iron. Some limestone also 
      occurs in the Lower Carboniferous rocks, usually associated with gypsum. 
      Localities where limestone beds are known to exist are marked on the 
      excellent map sheets of the Canadian Geological Survey. The surface of an 
      area underlain by limestone is usually characterized by caves, and 
      depressions known as "sink-holes." 
      Gypsum [Information about this mineral maybe 
      obtained in report on the Gypsum Deposits of be Maritime Province" by W: 
      F, Jennison Department of Mines, Ottawa. ]. - Gypsum beds are numerous 
      throughout the county where it is underlain by Lower Carboniferous rocks. 
      Places where these are known to occur may also be found by reference to 
      the geological map sheets. In several localities, the deposits are 
      extensive and thick, and where transportation facilities are suitable, 
      should be of economic importance. At Cheticamp there is a plant for the 
      manufacture of the calcined product. The raw material is of good quality, 
      the deposit a large one, and the distance from the quarries to the 
      shipping pier makes a short haulage, so that this industry should have a 
      future of promise, throughout the Lower Carboniferous. A gypsum district 
      is easily recognized by the pitted appearance of the surface produced by 
      the inverted-cone depressions known as "plaster holes." 
      Barytes. - At several places in the county 
      small veins of barytes occur, in the pre-Cambrain, the Devonian, or the 
      Carboniferous. In two localities it is found in some quantity-at Cape 
      Rouge, Cheticamp, and on the east side of Lake Ainslie. In both places, 
      the mineral occurs in the pre-Cambrian, either lying in, or in the 
      neighborhood of igneous rocks. At Cape Rouge, the deposits lie in schists, 
      the veins running about north and south and thinning to a few inches or 
      thickening to a few feet along the length. About 1903, there were produced 
      here 1,163 tons; but production has ceased, probably on account of the 
      nature of the deposit. 
      For a few years, in the early part of the 
      century, the deposits of Lake Ainslie were the only producers of barytes 
      in Canada. The district in which the mineral occurs lies along the flank 
      of the hills, extending from the outlet to Trout Brook. The barytes-bearing 
      rock is a reddish felsite with associated trap, the mineral occurring in 
      veins. The properties worked are at Scotsville, East Lake Ainslie and 
      Trout Brook. The boulders of Barytes found in the soil seem to paint to 
      the presence of some seven veins near the Gairloch Mountain road, north of 
      Trout Brook. The veins run approximately north and south varying in width, 
      the main vein being about eight feet. At certain points, branch veins come 
      in from the sides thus adding to the extent of the deposit. This deposit 
      has been a producer since the discovery of the commercial value of the 
      heavy white mineral. The product was hauled to and shipped from 
      Whycocomagh. It is now owned by the Brandram-Henderson, Ltd., and is used 
      by them in connection with the manufacture of paint. Last year (1920) 
      about 550 tons were mined. At East Lake Ainslie there are several veins, 
      the occurrence here and at Scotsville being similar to that of Trout 
      Brook. These properties are owned by the "Barytes Limited" company. A 
      refining plant was erected at Scotsville in 1901. The product was conveyed 
      across the lake, eight miles, by a steam barge to a special siding near 
      Strathlorne Station. Three veins have been worked here, the largest 
      varying from eight to sixteen feet. In 1914, the production was 612 tons. 
      The raw material at Scotsville is of a better quality than that at East 
      Lake Ainslie. In 1920, the plant of Barytes Limited was not in operation. 
      Magnetite and Hematite.-Occurrences of iron 
      oxides have been found in various parts of the county. At Upper Glencoe in 
      the Creignish Hills at an elevation of 500 feet above sea level, magnetite 
      occurs along the contact of pre-Cambrian limestone and granite. About ten 
      years ago, considerable work was done on this area by the Dominion Iron 
      and Steel Company in the way of trenching and sinking test-pits. A 
      magnetometric survey of the locality was also made in 1913, by E. Lindeman 
      for the Department of Mines, Ottawa [Summary Report of the Mines Branch of 
      the Department of Mines, 1913,]. The magnetite occurs in small, irregular 
      masses and lenses lying in succession along the contact. The survey and 
      exploration work done so far does not seem to warrant the belief that the 
      occurrence is of economic importance. 
      At various places on the slopes of Skye 
      Mountain [Summary Report of the Mines Branch of the Department of Mines, 
      1913.], iron oxides have also been found and exploration work has been 
      done, but with no satisfactory results. At Iron Brook', magnetite and 
      hematite occur in quartzite with a large amount of iron pyrites. At 
      Campbell's Brook', there is an occurrence of pre-Cambrian limestone 
      impregnated with grains of magnetite or iron-bearing silicates. At Logan 
      Glen 1, specular hematite occurs filling fissures in Lower Carboniferous 
      conglomerate. The veins are none of them over four inches in thickness. 
      Clay and Shale.-There is a number of 
      occurrences of tough, plastic surface clays of glacial origin throughout 
      the county. Some of the deposits are suitable for the manufacture of 
      bricks and tiles. At River Denys and at Orangedale, and a number of years 
      ago, at Mabou and at Judique, this clay was made into bricks. The economic 
      importance of other localities has not been tested. Shale, which is a 
      consolidated clay or mud, exists in thick bodies in parts of the Lower 
      Carboniferous and in the Coal Measures. This rock when crushed and 
      moistened has the properties of clay. The use of certain shales in the 
      manufacture of cement is well known. There are also the possibilities of 
      the shale being a fire-clay, or an oil-shale. In fact, one of the best 
      clays in the Province is found over-lying the Hussey coal seam at 
      Inverness. "This shale could be used for pressed brick, and, if mixed with 
      some burned clay, for firebrick, and it is also the kind used for mixing 
      with short-fibre asbestos for making asbestic [The Clay and Shale Deposits 
      of Nova Scotia and Portions of New Brunswick. Department of Mines, Ottawa. 
      Memoir No. 16-E]." 
      Magnesite. - About one mile east of Orangedale is a deposit of magnesite 
      discovered in 1916. The mineral is crystalline and in the magnesite body 
      are small cores of dolomite. It occurs in association with the dolomite 
      and gypsum of the Lower Carboniferous, and, according to Dr. Hayes, is 
      apparently of secondary origin, derived from the associated dolomite. 
      [Summary Report, Department of Mines, Ottawa, 1916.] The property was 
      acquired by the Nova Scotia Steel and Coal Company, but does not appear to 
      be of any great extent. The mineral has many uses among which an important 
      one is that for lining furnaces where great heat is required. 
      Some Other Minerals.- Gold, argentiferous 
      galena carrying some gold, and copper-bearing minerals occur in the 
      northern part of the county in the old rocks, but have not been proven to 
      be of commercial importance. This old mass of rock, however, is worthy of 
      some attention especially near the contact of igneous rocks with 
      sedimentaries. An interesting boulder containing a tungsten-bearing 
      mineral was some years ago found at Emerald, Northeast Margaree, but its 
      former resting place has not been located. For a number of years, oil 
      seepage was known from the Lower Carboniferous rocks around Lake Ainslie. 
      Exploitation by borings has failed to establish the presence of petroleum 
      in commercial quantity. 
      Building Stone. - In many localities, there 
      may be found good material for building purposes. That at Graham River, 
      near Judique, and at other places has been used locally. On Cheticamp 
      Island, there is an excellent sandstone of which the fine Roman Catholic 
      Church at Eastern Harbour was built. 
      The mineral wealth of the county will, 
      therefore, be seen to lie in its coal which awaits further development; 
      its limestone and gypsum, barely touched up to the present; clay and 
      shales which warrant study and possibly exploitation; barytes which also 
      warrants further study and exploitation; and building stone. In the rough, 
      hilly districts, and where so much of the rock is hidden by forest and 
      covered with glacial drift, there is always the possibility of further 
      discoveries. Soil. - 
      The mineral resources of a country are of such a nature that they 
      ultimately become exhausted. There is only a certain amount in the rocks, 
      and when this is extracted, its economic value is gone. Of a different 
      nature is another resource which the geologist claims as a part of his 
      domain. Soil results from the disintegration of rock with the addition of 
      a varying amount of decayed vegetable material. Inverness county has great 
      wealth in its soil The rich alluvium of the larger river valleys produces 
      excellent crops of hay, grain and vegetables, and some fruit. The glacial 
      drift of the uplands makes a very good soil, and even the slopes of the 
      hills yield excellent pasturage. The story of farming in Inverness is, 
      however, the same as that of most countries. The pioneer farmer exploited 
      a virgin soil, taking crop after crop from it without, in many cases, 
      returning to it an adequate supply of fertilizer. The result has been an 
      exhausted soil, and often abandoned farms, for it is only by conserving 
      its richness that the fertility of the soil may be retained ear after 
      year. It is a matter of general satisfaction and of prime importance to 
      the country to note that this frontier method of farming is steadily 
      giving place td scientific methods, with their suitable rotation of crops 
      and skilful utilization of proper fertilizers. The many beautiful, 
      prosperous looking farms throughout the county attest to this, and make a 
      strong appeal to the satiated city-dweller attest get a home in the 
      country where more of the gifts of a bountiful Nature may be obtained. It 
      is surely not too much to hope that, with all our modern improvements, the 
      time is not distant when the condition of the farmer will have removed 
      from it much of the present-day drudgery, and when with good roads, 
      telephone in general use, automobiles, and scientific methods on the farm, 
      the dweller in the country will be as near the town as he wishes to be, 
      and the "back-to-the-land" movement will have become firmly established.
