Early map of the Eastern Townships, Province of Quebec. 1875

This is an old map of the Eastern Townships (and adjacent portions of the Province of Quebec) from 1875. I found it in my old rectory at Rectory Hill in Inverness, County of Megantic. The last picture shows the boundaries of Inverness, and on the top corner of the municipality we can see Ch. which is the location of the rectory and of the former St-Stephens Church.
