The warning cry of this animal bears some re- semblance to the hurried barking of a small dog.* The squirrel-tribe are also very numerous in the coun- tries now under consideration. The chickaree or Hud- sou s Bay squirrel {Sciurus Hudsonius, Pennant) inha- bits the forests of white spruce-trees which cover so vast a portion of the fur-countries. It extends as far to the south as the middle states of America, and spreads north- wards to the utmost regions of the spruce-forests which cast their sombre shade as high as the sixty-ninth paral- lel. It burrows at the root of the largest trees, and sel- dom stirs abroad during cold or stormy weather; but even in the depth of winter it may be seen sporting imong the branches whenever the snow is brightened by a gleam of sunshine. When pursued it makes great leaps for a time from tree to tree, but ere long seeks a favourable op- portunity of descending into a burrow. However, it sel- dom voluntarily quits its own particular tree. During the winter season it collects the spruce-cones, and carry- ing them to the outskirts of its burrow, it picks out the seeds beneath the snow. Of the flying-squirrels of America we may mention the species (or variety?) discovered by Mr Drummond on the Rocky Mountains {Pteromys Sabrinus, var. B. alpi- nus). It inhabits dense pine-forests, and rarely ventures from its retreats except during the night. Passing over the sand-rats (genus Geomys, Rafinesquet), and the genus Aplodontia of Richardson,:}: we shall give a short account of the Canada porcupine {Hy
