In the darkness and the pouring rain it was hard to distinguish anything, but the white gleam of the sheets showed where the crutch was floating.
"Out of reach," muttered Ross in disgust. "Just my luck! How am I going to get it?"
It was a problem. The crutch was floating on the current above twelve feet beyond the reach of the boat's painter, let out to its utmost length. By stretching out with one of the oars, Ross was about four feet short. Just four feet, but so far as success was concerned, it might as well have been four miles.
If he jumped from the boat and swam for it, there was always a chance that the current would pluck him down before he could grasp the line, and then he would not only be in danger himself, but he would have lost all chance of saving his crippled friend. As long as he stayed either with the boat or with the house, there was a chance. It would be foolhardy to lose connection with both.
Then a brilliant idea struck him. Suppose he tied the painter of the boat under his arms, loosed the boat from the post and jumped into the water. He ought to reach the floating line before the current had taken up the slack of the boat's painter. If he left loose a long enough end, with a loop knot, he could fasten the rope from the boat to the line of sheets, and the boat would be made fast. The loop knot would unfasten itself and he could easily clamber into the boat, from the stern, since it was fastened to the line coming out from Anton's window. Then he could haul up the boat, hand over hand, as agreed upon, take Anton and the puppies aboard and strike out straight for the shore.
No sooner was the idea conceived than Ross proceeded to put it into action. Slipping the line around his arms, once, he tied a loop knot in front of his chest, where it would be easy to reach, leaving about three feet of rope hanging, untied the painter and shoved off the boat. The instant that the boat felt the current it yawed around, but, at the same moment, Ross jumped out and forward with all his might. The action sent the boat down-stream all the quicker, but in a second's time, Ross had grasped the floating crutch and had taken a turn with the loose end of the rope around it.
He was not an instant too soon, for a sharp tug at his chest, followed by a sudden release of the weight, told him that the loop knot had untied itself, as he hoped it would. Holding on to the sheet line with one hand, he rapidly passed the rope once under and through. Ross had not learned his knots from the Mississippi sailors for nothing, and as the boat came to the end of its tether and jerked on the line, the boy had the satisfaction of seeing the knot tighten. With the strain off, it was easy to take another half-hitch around the line, and the knot was secure beyond peradventure. He climbed aboard, raised a cheery cry to Anton, and commenced to pull the boat hand over hand along the line of sheets. It was only a moment before the little craft was bobbing on the flood, immediately beneath the window.
"Let's have the puppies first," cried Ross.
Anton's head disappeared from the window, and reappeared in a moment.
"Catch!" he cried and held out the basket.
