I found a couple of old pdf scans of two books by John MacLean. The first I had to unpick, edit and reassemble but the second one was in not too bad a condition so apart from removing a few blank pages and small amount of editing it is pretty much as I found it.

The Hero of the Saskatchewan
Life with the Ojibway and Cree Indians in Canada.

The Indians of Canada
Their Manners and Customs (Third Edition).

Remarks on the Great Nor'-West
By the author of Twenty-Five Years Service in the Hudson's Bay Territory - John MacLean (1869) (pdf)
