"Help me! help me, Harry!" he sung out, with good reason dreadfully alarmed.  I had just time to throw myself down at full length, and, by loaning over the rock, to seize his hand, before the bull, seeing him, with a terrific bellow made a full butt at him.  With a strength I did not think myself capable of exerting, I hauled him up to me, the bull's horns actually passing between his feet!  In his hurry, however, he dropped his gun at the foot of the rock, and the bull vented his rage and disappointment by giving it several butts as it lay on the ground; and I was in great hopes that he would strike the lock and make it go off--it would have astonished him not a little.  Jerry almost fainted with the fright the brute had given him, but he very speedily recovered, and then we looked round to see what sort of a place we were on.  We found that it was, fortunately, inaccessible on all sides; so we returned with much greater composure to watch the proceedings of our bovine enemies.  The other bulls had now come up, with their tails in the air, bellowing at the top of their voices, and tearing the ground up on all sides, and throwing the grass over their heads.  They appeared for some reason to be fearfully enraged against us.  There were seven bulls altogether.  Placed in the convenient position we were, we agreed that we could easily shoot them, and thus raise the siege; but on examining the contents of our pockets, we found that we had only got five bullets between us.  Now, supposing every bullet to have had in this case its billet, and to have mortally wounded an animal, that would have left two unprovided for; and even with two we had no desire to contend on the level ground.  Still we determined to do what we could; so I loaded and took a steady aim at the beast which had led on the attack.  The bullet struck him on the head; but his skull was thick, and though it wounded him severely, it did not enter his brain.  The pain made him tear up the ground more furiously, and bellow louder than before.  Jerry said he would try the next time; so I loaded, and he took the gun.  I thought he was going to make a good shot, but he was nervous, and the bullet only struck the beast's shoulder, nor did it increase the sweetness of his temper.  We had thus only three bullets, and all our enemies as vicious as ever.  The most important thing we agreed to be done was to get rid of the leader; so I took the gun again, and carefully loading, waited till he made a tilt right up to the face of the rock, really looking as if he had been going to try and leap up at us.  I tried to be perfectly cool, and fired.  The bullet struck him, I was certain of that, but it did not kill him, so I supposed that it had glanced off over his head.
