This little animal is very much like the Weasel in size and form, but it
usually prefers a colder climate, and makes its home in the northern
regions of Sweden, Norway, Russia, Siberia and Arctic America. These
animals do not often measure more than ten inches in length (not
including the tail) but their skins are very valuable. They bring a high
price, and a very important trade in them is carried on. In summer, the
Ermine is of a beautiful brown color above and white below, while the
tail is tipped with black. In winter the whole coat becomes a brilliant
white, with sometimes a slightly yellow tinge, the tip of the tail
remaining black. This is the season in which the fur is most valuable.
