The woodland caribou, as it is called by Dr. Richardson, is much larger than the barren ground 
reindeer found further north, but with smaller horns. According to this author, its northern 
limit is to the south of Hudson’s hay, in a stripe of low primitive rocks about one hundred 
miles wide, and reaching as far west as Lake Superior. To the south it extends through 
Canada as far as Hew Brunswick and Maine, and possibly, in former times, to the northern 
parts of New Hampshire, Vermont, and New York. It is not known as an inhabitant of the 
Rocky Mountains.
