And even as I thought these comradely thoughts, the whine of an arrow came from nowhere and on its heels the angry squall of the giant bear. I twisted round and looked over the wall. There was a shaft, fleshed in his furry thigh; and Halfspoor was gazing at me with no friendliness whatever. It was no time for idle wondering as to the source of that arrow. Indeed, I think I knew instinctively who had sent it over my head into the courting bruin. But as I leaped the scattered rocks and dodged the higher walls of that ruinous place, I was seeking only an advantageous battleground, not the stealthy prowler with the bow. At my back I could hear the wrathful snorting of the knifetooth bear, the swift thud-thud of his enormous paws, and the rattle of stones dislodged by his whirlwind passage. My bow was in my hand, a lean arrow nocked on the cord. Hastily as I ran I gripped two others between the fingers of my left hand. Skirting a heap of gray lichen-grown rubble, I whirled on my toes and sent the first missile back at him. When I could risk a glance again, he had fallen a little behind, being some forty long paces in the rear, and was swatting impatiently at the broken shaft protruding from his thigh. I think my own shot had missed him, and considering my haste, I was not surprised. I halted and taking a decent aim I loosed one at his head. At the same moment he roared loudly, opening his immense mouth to its full extent. Luck not being with me, the arrow glanced off one of his overgrown fangs with a sharp click, which appeared to startle Halfspoor considerably, because he stopped dead and blinked down his muzzle in a quaint way. I shot the third of my arrows and tore a long red furrow up one gray-sprinkled cheek. Then, as he was nearly atop me in four sudden raging bounds, I fled like a hare amongst the ruins. His coughing and bellowing echoed like implacable thunder in my ears. * * * * *
