"Now watch me, for your life may depend upon it," and the corporal proceeded to give them the low parry which is useful when you are taking trenches and find a _chevaux-de-frise_ of the enemy's bayonets confronting you. Each rank knocked an imaginary bayonet aside and pointed at invisible feet. The high parry followed. So far the men had been merely nodding at each other across a space of some twelve yards, and it was hot work and tedious. The sweat ran down their faces, which glistened in the sun. "Now I'm going to give you the butt exercises"; they brightened visibly. "I am pointing--so!--and 'ave been parried. I bring the butt round on 'is shoulder, using my weight on it. I bring my left leg behind 'is left leg. I throw 'im over. Then I give the beggar what for. So!" The words were hardly out of his mouth before he had thrown himself upon the nearest private and laid him prostrate. The others smiled faintly as No. 98678 picked himself up and nonchalantly returned to his old position as if this were a banal compliment. "Now then. First butt exercise." One rank advanced upon the other, and the two ranks were locked in a close embrace. They remained thus with muscles strung like bowstrings, immobile as a group of statuary. "That'll do. Now I'll give you the second butt exercise. You bring the butt round on 'is jaw--so!--and then kick 'im in the guts with your knee." Perhaps the section, which stood like a wall of masonry, looked surprised; more probably the surprise was mine. But the corporal explained. "Don't think you're Tottenham Hotspur in the Cup Final. Never mind giving 'im a foul. You've got to 'urt 'im or 'e'll 'urt you. Kick 'im anywhere with your knees or your feet. Your ammunition boots will make 'im feel it. No!"--he turned to a young private whose left hand was grasping his rifle high up between the fore-sight and the indicator--"You mustn't do that. Always get your 'and between the back-sight and the breech. So! The back-sight will protect your fingers from being cut by the other fellow. Now the third butt exercise." As we turned away the Major thoughtfully remarked to me, "There isn't much of that in the Infantry Manual. But the corporal knows his job. When you're in a scrap you haven't time to think about the rules of the game; the automatic movements come all right, but in a clinch you've got to fight like a cat with tooth and claw, use your boots, your knee, or anything that comes handy. Perhaps that's why your lithe little Cockney is such a useful man with the bayonet. Now the Hun is a hefty beggar, and he isn't hampered by any ideas of playing the game, but he's as mechanical as a vacuum brake, and he's no good in a scrap."
