And there was, or there had been, another animal. Once, under the broad daylight, on that open stony hillside, where the baby pines were growing, scarcely tall enough to be a badge for a MacGregor's bonnet, I came suddenly upon his innocent body, lying mummified by the dry air and sun: a pigmy kangaroo. I am ingloriously ignorant of these subjects; had never heard of such a beast; thought myself face to face with some incomparable sport of nature; and began to cherish hopes of immortality in science. Rarely have I been conscious of a stranger thrill than when I raised that singular creature from the stones, dry as a board, his innocent heart long quiet, and all warm with sunshine. His long hind legs were stiff, his tiny forepaws clutched upon his breast, as if to leap; his poor life cut short upon that mountain by some unknown accident. But the Kangaroo rat, it proved, was no such unknown animal; and my discovery was nothing. Crickets were not wanting. I thought I could make out exactly four of them, each with a corner of his own, who used to make night musical at Silverado. In the matter of voice, they far excelled the birds, and their ringing whistle sounded from rock to rock, calling and replying the same thing, as in a meaningless opera. Thus, children in full health and spirits shout together, to the dismay of neighbours; and their idle, happy, deafening vociferations rise and fall, like the song of the crickets. I used to sit at night on the platform, and wonder why these creatures were so happy; and what was wrong with man that he also did not wind up his days with an hour or two of shouting; but I suspect that all long-lived animals are solemn. The dogs alone are hardly used by nature; and it seems a manifest injustice for poor Chuchu to die in his teens, after a life so shadowed and troubled, continually shaken with alarm, and the tear of elegant sentiment permanently in his eye. There was another neighbour of ours at Silverado, small but very active, a destructive fellow. This was a black, ugly fly--a bore, the Hansons called him--who lived by hundreds in the boarding of our house. He entered by a round hole, more neatly pierced than a man could do it with a gimlet, and he seems to have spent his life in cutting out the interior of the plank, but whether as a dwelling or a store-house, I could never find. When I used to lie in bed in the morning for a rest--we had no easy-chairs in Silverado--I would hear, hour after hour, the sharp cutting sound of his labours, and from time to time a dainty shower of sawdust would fall upon the blankets. There lives no more industrious creature than a bore.
