One day in spring four men were riding on horseback along a country road. These men were lawyers, and they were going to the next town to attend court.  There had been a rain, and the ground was very soft. Water was dripping from the trees, and the grass was wet. The four lawyers rode along, one behind another, for the pathway was narrow, and the mud on each side of it was deep. They rode slowly, and talked and laughed and were very cheerful. As they were passing through a group of small trees, they heard a great fluttering over their heads and a weak sound made by small birds in the grass by the roadside. "Stith! Stith! Stith!" came from the leafy branches above them. "Cheep! cheep! cheep!" came from the wet grass. "What is the matter here?" asked the first lawyer, whose name was Speed. "Oh, it's only some old robins !"said the second lawyer, whose name was Hardin. "The storm has blown two of the little ones out of the nest. They are too young to fly, and the mother bird is worried about them." "What a pity! They'll die down there in the grass," said the third lawyer. "Oh, well! They're nothing but birds," said Mr. Hardin. "Why should we bother?" "Yes, why should we?" said Mr. Speed. The three men, as they passed, looked down and saw the little birds fluttering in the cold, wet grass. They saw the mother robin flying about, and crying to her mate. Then they rode on, talking and laughing as before. In a few minutes they had forgotten about the birds. But the fourth lawyer, whose name was Abraham Lincoln, stopped. He got down from his horse and very gently took the little ones up in his big warm hands. They did not seem frightened, but cried softly, as if they knew they were safe. "Never mind, my little fellows," said Mr. Lincoln "I will put you in your own cozy little bed." Then he looked up to find the nest from which they had fallen. It was high, much higher than he could reach. But Mr. Lincoln could climb. He had climbed many a tree when he was a boy. He put the birds softly, one by one, into their warm little home. Two other baby birds were there that had not fallen out. All cuddled down together and were very happy. Soon the three lawyers who had ridden ahead stopped at a spring to give their horses water. "Where is Lincoln?" asked one. All were surprised to find that he was not with them. "Do you remember those birds?" said Mr. Speed. "Very likely he has stopped to take care of them." In a few minutes Mr. Lincoln joined them. His shoes were covered with mud; he had torn his coat on the thorny tree. "Hello, Abraham!" said Mr. Hardin. "Where have you been?" "I stopped a minute to give those birds to their mother," he answered. "Well, we always thought you were a hero," said Mr. Speed. "Now we know it." Then all three of them laughed heartily. They thought it so foolish that a strong man should take so much trouble just for some worthless young birds. "Gentlemen," said Mr. Lincoln, "I could not have slept tonight, if I had left those helpless little robins to die in the wet grass." Abraham Lincoln afterwards became very famous as a lawyer and statesman. He was elected president. Next to Washington he was the greatest. It can be inferred that "stith" was the sound made by   _  .
