When he had stepped the sixtieth yard, he faced about, and stood erect, placing his heels together. He then extended his right arm, raising it until his hand was on a level with his shoulder, and holding the shell in his fingers, flat side to the front, shouted back-- "Now, Billee, shoot, and be hanged to yur!" The shell was slightly concave, the concavity turned to the front. The thumb and finger reached half round the circumference, so that a part of the edge was hidden; and the surface turned towards the marksman was not larger than the dial of a common watch. This was a fearful sight. It is one not so common among the mountain men as travellers would have you believe. The feat proves the marksman's skill; first, if successful, by showing the strength and steadiness of his nerves; secondly, by the confidence which the other reposes in it, thus declared by stronger testimony than any oath. In any case the feat of holding the mark is at least equal to that of hitting it. There are many hunters willing to risk taking the shot, but few who care to hold the shell. It was a fearful sight, and my nerves tingled as I looked on. Many others felt as I. No one interfered. There were few present who would have dared, even had these two men been making preparations to fire at each other. Both were "men of mark" among their comrades: trappers of the first class. Garey, drawing a long breath, planted himself firmly, the heel of his left foot opposite to, and some inches in advance of, the hollow of his right. Then, jerking up his gun, and throwing the barrel across his left palm, he cried out to his comrade-- "Steady, ole bone an' sinyer! hyar's at ye!" The words were scarcely out when the gun was levelled. There was a moment's death-like silence, all eyes looking to the mark. Then came the crack, and the shell was seen to fly, shivered into fifty fragments! There was a cheer from the crowd. Old Rube stopped to pick up one of the pieces, and after examining it for a moment, shouted in a loud voice;-- "Plumb centre, by--!" The young trapper had, in effect, hit the mark in the very centre, as the blue stain of the bullet testified. CHAPTER TWENTY ONE. A FEAT A LA TELL. All eyes were turned upon the strange Indian. During the scene described he has stood silent, and calmly looking on. His eye now wanders over the ground, apparently in search of an object. A small convolvulus, known as the prairie gourd, is lying at his feet. It is globe-shaped, about the size of an orange, and not unlike one in colour. He stoops and takes it up. He seems to examine it with great care, balancing it upon his hand, as though he were calculating its weight. What does he intend to do with this? Will he fling it up, and send his bullet through it in the air? What else?
