The tired white horses looked up suddenly from their hay, and perceiving this black apparition of the forest, snorted and tugged at their halters.
With a frightful bellow, half squeal, half roar, the moose rose twelve feet tall on his hind legs, and rushed at the one hitched nearest. The horse broke its halter, ran headlong against its mate, recoiled, bumped into a tree trunk, and then—the trees standing thick in front of it—backed over the bank and went out of sight down the bluff, the moose bounding after it, still bellowing hoarsely.
The other horse had also broken its halter and ran off, while the two boys stood amazed and alarmed at this tremendous exhibition of animal ferocity.
"Nat! Nat! He will kill that horse!" Jonathan exclaimed, and they both ran to look over the bank. Horse and moose were now down near the water, where the river ran deep and swift under the steep bank, the horse trying vainly to escape through the tangled alder brush, the moose savagely pursuing.
The sight roused the boys to save their horse. Axe in hand, Jonathan ran and slid down the bluff side, catching hold of trees and bushes as he did so, to keep from going quite into the river. Nat followed him, with the gun which he had hastily primed. Both horse and moose were now thrashing amidst the alder clumps.
"Shoot him, shoot him!" Jonathan shouted. "Why don't you fire? Oh, let me have that gun!"
It is not as easy as an onlooker often thinks to shoot an animal, even a large one, in rapid motion, particularly among trees and brush; something constantly gets in the way. Both animals were now tearing along the brink of the deep stream, stumbling headlong one second, up the next, plunging on. As often as Nat tried to steady himself on the steep side of the bluff for a shot, either the horse was in the way or both animals were wholly concealed by the bushes. Moreover, the boys had to run fast through the brush to keep them in sight. Nat could not shoot with certainty, and Jonathan grew wild over the delay.
"Shoot him yourself, then!" Nat retorted, panting.
Jonathan snatched the gun and dashed forward, Nat picking up the axe and following after. On they ran for several hundred yards, barely keeping pace with the animals. Jonathan experienced quite as much difficulty in getting a shot as Nat had done.
