Donald reflected a moment. "Had you thought, father, of trying him up-stairs?" he asked. "No, I hadn't. We need a foreman up there, but I had not considered Thornton for the position. That is a happy inspiration, son. We will give him a try. He may make good yet." Accordingly Thornton was sent to the upper floors of the warehouse, where the wool was stored. Here were great piles of loose wool reaching from floor to ceiling. Some piles contained only the finest wool; other piles that which was next-best in quality; still other piles were made up of the coarser varieties. There were piles of scoured wool, piles of South American and Australian wool--wool, wool, wool everywhere! With keen interest Thornton looked about him. He wandered from one vast pyramid of fleeces to another, catching up handfuls of the different varieties and examining them. Then he walked to where the men were busy opening the first spring shipments of wool from Crescent Ranch. The wool was emptied from the sacks onto the floor in great heaps, and crews of men--skilled in judging the fiber--set to work to sort it, separating the different qualities into piles. Donald, who was looking on, saw a smile pass over Thornton's face--the first smile that had brightened it in days. Then, almost instinctively, the ranchman rolled up his sleeves and began to grade wool with the other men. He worked rapidly, for he was thoroughly familiar with what he was doing. The next day when Donald went up-stairs he found Thornton directing a lot of green hands who were packing the sorted, or graded wool, in bags. Later in the week it chanced that the man who weighed the wool fell ill and the Westerner took his place at the scales, seeing that the sacks of wool were correctly weighed and recorded, that they were sewed up strongly, and marked for shipping. Gradually the men, recognizing Thornton's ability, began to defer to his judgment. The month was not out before Clark & Sons began to wonder what they had done before Thornton came. So familiar did he make himself with the stock that even Mr. Clark sent for and consulted him about orders and shipments. "He is proving himself a thoroughly useful man, Don," declared Mr. Clark rubbing his hands with satisfaction. "His knowledge of the ranch and of the wool itself is invaluable. It is just a case of putting the peg into the proper hole. Thornton was like a fish out of water here in the office. Now he is in his element. I shall make him foreman of the shipping department--a position just suited to him, and which he will fill well." "I am so glad he has made good, father," said Donald. "Now, what are you going to do about an assistant for Sandy? That is the next question to settle, I suppose. Have you found any one?"
