to do to pass the dreary time. His hand wandered into his pocket and his face lit up with a glow of gratitude that was prayer, though he did not know it. Then furtively the percussion-cap box came out. He released the tick and put him on the long flat desk. The creature probably glowed with a gratitude that amounted to prayer, too, at this moment, but it was premature: for when he started thankfully to travel off, Tom turned him aside with a pin and made him take a new direction.
Tom's bosom friend sat next him, suffering just as Tom had been, and now he was deeply and gratefully interested in this entertainment in an instant. This bosom friend was Joe Harper. The two boys were sworn friends all the week, and embattled enemies on Saturdays. Joe took a pin out of his lappel and began to assist in exercising the prisoner. The sport grew in interest momently. Soon Tom said that they were interfering with each other, and neither getting the fullest benefit of the tick. So he put Joe's slate on the desk and drew a line down the middle of it from top to bottom.
"Now," said he, "as long as he is on your side you can stir him up and I'll let him alone; but if you let him get away and get on my side, you're to leave him alone as long as I can keep him from crossing over."
"All right, go ahead; start him up."
The tick escaped from Tom, presently, and crossed the equator. Joe harassed him 'a while, and then he got away and crossed back again. This change of base occurred often. While one boy was worrying the tick with absorbing interest, the other would look on with interest as strong, the two heads bowed together over the slate, and the two souls dead to all things else. At last luck seemed to settle and abide with Joe. The tick tried this, that, and the other course, and got as excited and as anxious as the boys themselves, but time and again just as he would have victory in his very grasp, so to speak, and Tom's fingers would be twitching to begin, Joe's pin would deftly head him off, and keep possession. At last Tom could stand it no longer. The temptation was too strong. So he reached out and lent a hand with his pin. Joe was angry in a moment. Said he:
"Tom, you let him alone."
