You might take a Christmas walk over the ice and visit a muskrat's house of sticks and other rubbish. If the occupants are at home, you will notice a frosty spot on one side of the mound. A muskrat hunter would thrust his spear through the thin wall and impale one or more of the rats upon its tines. Many of the clods composing the house bear the nose-print of the maker.

While sleigh-riding you are likely to see a flock of trim, sober-colored birds perched close together, feeding on the berries of the mountain ash tree or on decayed apples. They have crests and wax-like red dots on the inner feathers of their wings. These are cedar-birds, or cedar waxwings. They often remain with us throughout the year.

"The name 'burl' is applied to all excrescent growths on trees, except true knots. The origin of these wart-like swellings is imperfectly known, but they can generally be attributed to injuries by woodpeckers, gall insects, and to the irritating and continued growth of fungi in the woody tissues at such points." (Adams.)

A flock of pine grosbeaks feeding on buds in a maple or an apple tree on a cold winter's day is a pleasing sight for any bird lover. They are the size of a robin, and the male has a rose-colored head, neck, breast, and back. They are quiet birds and very tame, even permitting a person to climb the tree and approach within a few feet, before they take flight. It is only during the severest weather that they migrate south into southern New York, Pennsylvania, and New England.
