He soon learned to reach up on his hind legs and gnaw the standing plant. The management of a dry and slippery corn-ear at first presented some difficulty, but, as his muscles strengthened, he found himself able to sit up on his haunches and hold it squirrel-fashion in his fore-paws, nibbling, to begin with, at the pointed end, which is the best way into most things. Once, as the family were grubbing together, a nut turned up at the back of the pile. After a desperate conflict, he secured it, but, the tough shell was too much for him. It takes a red vole's training to reduce a nut. [Illustration: NIBBLING, TO BEGIN WITH, AT THE POINTED END.] So the weeks passed on, and he grew thicker and sturdier and more furry. He was never graceful, like his cousin the red vole, for his face was blunted, his eyes small, and his tail ridiculously insignificant. Nor could he cover the ground with the easy swinging jump that makes one suspect relationship between the red vole and the wood-mouse. Still for a common, vulgar, agrarian vole, he was passable enough, and could hold his own, tooth and nail, with his nest-fellows. He was five weeks old before he commenced to go out foraging on his own account. He never ventured far, but contented himself with timorous excursions along the banks of the watercourse, crouching amid the undergrowth, and ready, at the first scent of danger, to glide with flattened body back to cover. Sometimes he accompanied his mother on her visits to distant portions of the colony, but the old vole more often left her octet behind, and then he would lie huddled up with his companions, waiting for the squelching sound of her footsteps, as she returned across the mud, and quarrelling in anticipation of what she would bring. [Illustration: READY, AT THE FIRST SCENT OF DANGER, TO GLIDE BACK TO COVER.] Now and again a different sound would reach the hollow--the dragging tail swish of the water-vole, or the fussy scramble of some belated moorhen. These he soon learned to distinguish from the stealthy, broken, hanging footfall of the beast of prey. When that was heard, both he and his companions would crouch together in the darkest corner of the burrow and hold their breath. Once such a sound stopped abruptly and close at hand; a faint foetid odour permeated from without, and he felt instinctively that the enemy was at the gate. The danger passed, but that night the old vole failed to return. The night following the same sound came, and ceased. This time, however, the silence was succeeded by a fierce scratching, and he soon realized that the entrance to the nest was blocked, and that something, bigger and stronger than he yet knew of, was working its way nearer and nearer. There was a clatter of falling stones and earth, and the "something" was whirling in their midst. Wild confusion followed. The whole interior of the nest seemed occupied by a swift-circling, curling, sinuous form.
