So far, he had been hunting as he advanced, moving slowly and quietly and watching the ground and the trees both. Now he went on, his gun unloaded and the barrel slanted up and back to facilitate its passage through brier and undergrowth, approaching as it grew louder and louder that steady savage somehow queerly hysterical beating of metal on metal, emerging from the woods, into the old clearing, with the solitary gum tree directly before him. At first glance the tree seemed to be alive with frantic squirrels. There appeared to be forty or fifty of them leaping and darting from branch to branch until the whole tree had become one green maelstrom of mad leaves, while from time to time, singly or in twos and threes, squirrels would dart down the trunk then whirl without stopping and rush back up again as though sucked violently back by the vacuum of their fellows frenzied vortex.
