Nobody ventures to say how infrequently and at what hour the small fry visit the spring. There are such numbers of them that if each came once between the last of spring and the first of winter rains, there would still be water trails. I have seen badgers drinking about the hour when the light takes on the yellow tinge it has from coming slantwise through the hills. They find out shallow places, and are loath to wet their feet. Rats and chipmunks have been observed visiting the spring as late as nine o'clock mornings. The larger spermophiles that live near the spring and keep awake to work all day, come and go at no particular hour, drinking sparingly. At long intervals on half-lighted days, meadow and field mice steal delicately along the trail. These visitors are all too small to be watched carefully at night, but for evidence of their frequent coming there are the trails that may be traced miles out among the crisping grasses. On rare nights, in the places where no grass grows between the shrubs, and the sand silvers whitely to the moon, one sees them whisking to and fro on innumerable errands of seed gathering, but the chief witnesses of their presence near the spring are the elf owls. Those burrow-haunting, speckled fluffs of greediness begin a twilight flitting toward the spring, feeding as they go on grasshoppers, lizards, and small, swift creatures, diving into burrows to catch field mice asleep, battling with chipmunks at their own doors, and getting down in great numbers toward the lone juniper. Now owls do not love water greatly on its own account. Not to my knowledge have I caught one drinking or bathing, though on night wanderings across the mesa they flit up from under the horse's feet along stream borders. Their presence near the spring in great numbers would indicate the presence of the things they feed upon. All night the rustle and soft hooting keeps on in the neighborhood of the spring, with seldom small shrieks of mortal agony. It is clear day before they have all gotten back to their particular hummocks, and if one follows cautiously, not to frighten them into some near-by burrow, it is possible to trail them far up the slope.
