I soon observed they were busy at work, carrying in dry grass, fir-fronds, roots, and moss, and constructing a nest in the clefts between the stones, clearly for winter-quarters. The nests were of large size, some of them consisting of as much material as would fill a good-sized basket. One nest was evidently the combined work of several little labourers, and destined for their joint habitation. There were no provisions stored away, neither do I think they garner any for winter use, but simply hibernate in the warm nest; which, of course, is thickly covered with snow during the intense cold of these northern latitudes, thus more effectually preventing radiation and waste of animal heat. Their food consists entirely of grass, which they nibble much after the fashion of our common rabbit. They never burrow or dig holes in the ground, but pass their lives among the loose stones. Who can fail to trace the evidence of Divine care in colouring the fur of this defenceless creature in a garb exactly resembling the grey lichen-covered fragments amongst which he is destined to pass his life? So closely does the animal approximate in appearance to an angular piece of rock when sitting up, that unless he moves it takes sharp eyes to see him; and the cry or whistle is so deceptive that I imagined it far distant, when the animal was close to me. The species described and figured by Sir John Richardson—F.B.A., plate 19, _Lepus (Lagomys) princeps_, the little Chief Hare—I first saw at Chilukweyuk lake, and next on the trail leading from Fort Hope, on the Fraser river, to Fort Colville. The little fellows were in a narrow gorge, as well as among loose stones. It was about the same date as in the preceding year that I had seen _Lagomys minimus_ making its nest; but here not a trace of nest could I see, nor any evidence of an attempt to make one. I soon after returned again by the same trail. The snow having now fallen to the depth of about six inches, completely covering up the rocks and stones, all the animals had disappeared; and although I searched most carefully, there was not a hole or track in the snow, to show they had ever left their quarters to feed or wander about. As it was quite impossible a nest could have been made in the interim, it is perfectly certain they hibernate in holes without a nest; whereas _Lagomys minimus_, living at a much greater altitude, makes a nest to sleep through the winter.
