Other fungi too were plentiful after that rain. Some grew under the trees, some on rotten logs, others out in the open. Some were good to eat—better even than mushrooms—but others were poisonous. Mother never passed a new one without showing us which were fit to eat and which were not. There was a brilliant scarlet kind which she warned us against strongly; well I remember how she scolded me one day because just for fun I pulled one up, and stuck it stalk down in a fork of a tree. I did not repeat the experiment, for it left a bad taste in my mouth for hours afterwards. About this time my coat began to change. Squirrels that are born early in the spring have fur of a greyish-brown hue very like the coats that old squirrels put on in winter, but we, being June kittens, had summer suits of red-brown without any ear tufts, or any hair on the palms of our hands. First, my tail changed and grew darker, much heavier and more bushy. It turned to a blackish-brown, quite different from its previous bright chestnut-red hue. My coat, too, began, but more slowly, to lose its ruddy tint, and to assume its winter colouring. I became dark brownish-red on the head and back. My white under parts changed to grey, which spread along my sides. It also grew longer, softer and warmer, and my ear tufts began to show. During the summer a squirrel has but a few hairs on the points of the ears, but winter brings a thick tuft a full inch in length. We squirrels have a strange peculiarity. We are the only living creatures, so far as I know, who change our coats twice a year and our tails once only. As I have said, we change our coats in spring and again before the cold weather, but our tails once only—in autumn. A healthy squirrel looks at his best in late September and early October, for at that time his new brush is extremely bright, while his new grey-brown coat is rich and long. Both fade during the cold weather, the fur especially becoming during long frosts of a yellowish rusty hue. There are, I believe, some squirrels, near relatives of our own, living in Canada, who turn almost white in winter. But as—luckily for ourselves—all we squirrels have the sense to sleep away most of the cold weather, we have not the same need to conceal ourselves by assuming the colour of the snow, as have Arctic hares and foxes and many other animals which are obliged to work and forage for a living during the hard weather.
