It seemed impossible that anything without wings could cover the great gap between the two trees; but the blackcat knew to an inch what he could do, and almost to an inch did the distance tax his powers. In a wide parabola his black body whizzed through the air half a hundred feet above the ground, beginning as a round ball of fur, which stretched out until the fisher hung full length at the crest of his spring. If the tree had been a scant six inches farther away, the blackcat would never have made it. As it was, the huge clutching, horn-colored claws of his forepaws just caught, and held long enough to allow him to clamp down his hold with his hind paws.
The marten, who had started fifty feet ahead of the blackcat and had lost his distance by having to climb up, jump, and then climb down, passed along the trunk of the pine on his way to the ground just as the blackcat landed, his lead cut down to a scant ten feet.
