Toby made the flivver fairly bound along, such was his eagerness to arrive at the scene of all the excitement. Twenty seconds later he gave a loud cry. "Look, Jack, there's some one floundering out there, and throwing up his arms. It's our Joel Jackman, I do believe! and great Caesar! he's got a cramp and is drowning!" CHAPTER XIII WHEN THE CRAMP SEIZED JOEL What the excited Toby had just said in thrilling tones was undoubtedly the truth. There was no "fooling" about the frantic actions of the boy who was struggling so desperately out in the lake. He was threshing the water furiously, now vanishing partly underneath, only to come up again in a whirl of bubbles. When a cramp seizes any one, no matter if he should happen to be a champion in the art of swimming, he is always in mortal peril of his life, especially should he be at some distance from the shore, and in deep water. It almost paralyzes every muscle, and the strongest becomes like a very babe in its spasmodic clutch. Joel Jackman was long-legged and thin, but had always been reckoned one of those wiry sort of chaps, built on the order of a greyhound. He could run like the wind, and jump higher than any fellow in all Chester, barring none. But when that awful cramp seized him in the cold water of Lake Constance, lie found himself unable to make any progress toward shore, distant at least fifty feet. It was all he could do to keep his head above water, struggling as he was with the fear of a terrible death before his eyes. His two comrades were running up and down on the shore; not that they were such arrant cowards but what they would have been willing to do almost anything to help Joel; but unfortunately they had lost their heads in the sudden shock; and as Toby afterwards contemptuously said, "acted like so many chickens after the ax had done its foul work." Jack sized up the situation like a flash. "Toby, you get one of those boards over yonder, and come out to help me if I'm in trouble, understand?" he jerked out, even as the flivver came to a sudden stop, and he was bounding over the side regardless of any exit. "All right, Jack; you bet I will!" Toby shouted, following suit. Jack began to shed his outer clothes as he ran swiftly forward. First his cap went, and then his coat. He had low shoes on so that he was able to detach them with a couple of quick jerks, and at the loss of the laces. Two seconds, when at the verge of the water, sufficed for him to get rid of his trousers, and then, he went in with a rush. Toby meanwhile had tried to follow suit even as he made for the boards in question. It had been just like Jack to glimpse these in the beginning, while those other fellows apparently did not know a board was within half a mile. Seeing what Toby meant to do, the two swimmers followed suit, so that presently the whole three of them had each picked up a plank, and were pushing out with it.
