After that the wood mice were safe so far as I was concerned. Not a trout, though he were big as a salmon, would ever taste them, unless they chose to go swimming of their own accord; and I kept their table better supplied than before. I saw much of their visiting back and forth, and have understood better what those tunnels mean that one finds in the spring when the last snows are melting. In a corner of the woods, where the drifts lay, you will often find a score of tunnels coming in from all directions to a central chamber. They speak of Tookhees' sociable nature, of his long visits with his fellows, undisturbed by swoop or snap, when the packed snow above has swept the summer fear away and made him safe from hawk and owl and fox and wildcat, and when no open water tempts him to go swimming where Skooktum the big trout lies waiting, mouse hungry, under his eddy. The weeks passed all too quickly, as wilderness weeks do, and the sad task of breaking camp lay just before us. But one thing troubled me--the little Tookhees, who knew no fear, but tried to make a nest in the sleeve of my flannel shirt. His simple confidence touched me more than the curious ways of all the other mice. Every day he came and took his crumbs, not from the common table, but from my, hand, evidently enjoying its warmth while he ate, and always getting the choicest morsels. But I knew that he would be the first one caught by the owl after I left; for it is fear only that saves the wild things. Occasionally one finds animals of various kinds in which the instinct of fear is lacking--a frog, a young partridge, a moose calf--and wonders what golden age that knew no fear, or what glorious vision of Isaiah in which lion and lamb lie down together, is here set forth. I have even seen a young black duck, whose natural disposition is wild as the wilderness itself, that had profited nothing by his mother's alarms and her constant lessons in hiding, but came bobbing up to my canoe among the sedges of a wilderness lake, while his brethren crouched invisible in their coverts of bending rushes, and his mother flapped wildly off, splashing and quacking and trailing a wing to draw me away from the little ones.
