After their work along the railroad in the vicinity of McMinnville, the Riverlawns were ordered to Triune, where they went into camp just outside of the town, on the bank of a little creek backed up by a hemp field. Their hospital tent was located in the midst of this field, and here, on a cot, lay Deck, suffering in a manner that was new to the doctors caring for him. At times the major was out of his mind, then he would be rational, but so weak he could scarcely talk. "It's awful--simply awful," said Artie, to his Cousin Sandy one day. "It's the worst case I ever heard of." "It is too bad," replied the second lieutenant, of Captain Gadbury's command. "I wish I could do something for him, I really do." There was a great change in Sandy Lyon. He was no longer the wild fellow he had been. Army discipline had made a man of him, and he was a first-class soldier in every sense of the word. Only one thing he regretted, that being that he had not become attached to the Engineering Corps. He declared that as soon as the war was over he was going to study hard and become an architect and builder. The change in Titus Lyon was also great. He had kept the pledge, and his brother Noah could not have had a more useful adjutant. The brothers were real brothers once more, much to the satisfaction of Titus's wife and daughters, as well as the other members of the Lyon family at large. At last Colonel Lyon began to think of sending Deck home, although he hated the thought of having the youth where he could not see him constantly. Moreover, Mrs. Lyon had not been informed of how much Deck was suffering, and the truth might give her a shock. It was three weeks previous to the movement of the army upon the Confederate forces that the major began to mend. At first the change was gradual, but inside of ten days he was up on his feet. His appetite now came back, and he began to walk around, declaring that he would soon be as well as ever. "Deck, you must take no more such risks--I positively forbid it," said Colonel Lyon, when calling on his son one evening. "All right, father, I'll try to be more careful," answered Deck, with a faint smile. "To tell the truth, I didn't realize what a risk it was until it was too late to turn back. On that account, I don't think I am half the hero the boys are making me out to be." "I have a letter for you," continued the colonel, producing the communication. "It will certainly interest you, for it is from the Confederate soldier you rescued from the mill." "Is that so? How is he doing?" "He is doing too much--he got so well that he ran away yesterday." "Ran away!" "Exactly; and left that letter behind. Read it," and Deck did so. The communication ran as follows:-- "MAJOR DEXTER LYON:--
