Wide observation with suitable thinking seems to give one prudence and steadiness of mind in emergencies. In several trying instances this proved to be true in Lincoln's experience, long before the civilization of America was depending upon his warm heart and clear head. Many such instances seem as trivial as the trimmings of a sapling, but they are the perfecting process that makes possible the great oak. When his flatboat was finished at New Salem, it was necessary to have a canoe that was to trail along behind the boat. The canoe was made from a dugout log. When it was shoved into the booming Sangamon river, his two friends, John Seamon and Walter Carmon, sprang into it for the first ride, but the stream was too swift for them. The current began to sweep them away down stream. "Head up stream," Lincoln shouted, "and work back to shore." But they could not beat the rush of water. Nearing the wreck of an old flatboat, they tried to pull the canoe in among the timbers and hold themselves fast. Seamon caught hold of a stanchion as they came by and the canoe was overturned, leaving Seamon clinging to the timber and Carmon being borne down stream, clinging to the slippery log. Lincoln yelled for Carmon to swim for the branches of an elm tree that swung in the high water near the shore. Carmon did this. Lincoln then called to Seamon to swim for the tree with Carmon and they could be rescued together. It was a very cold April day and the men were in danger of becoming too benumbed to hold on. By this time the whole village of New Salem was gathered at the bank. Lincoln procured a rope, which he fastened to a large log. The log was pushed into the water and a venturesome young fellow named Jim Darrell bestrode the log that was to be floated down stream to the rescue. The log went straight to the tree all right, but the young man was too eager to help his fellows. In the struggles the log was turned and so caught in the current that it was swept away from them and there were now three to be rescued from the tree. The log was towed back. Lincoln tied another rope to it, and held the end of the rope in his hand. He then mounted the log to take the dangerous ride himself. As the log came into the tree, he threw the rope around a limb and held fast. In another minute all three of the shipwrecked men were safely astride the log. He then told the people to let go the guiding rope. The well-calculated result was that the current against the log, and the pull on the rope fastened to the limb, swung them safely around to the shore.
