"I don't believe I could," said Jack, looking with his straight, frank gaze into the gentleman's face. "You see, sir, if I broke my word with him, I should not be the kind of boy to be relied on that you want."

"I guess you are about right," said Mr. Lang, with a sigh. "Come and see me when your time is out; I dare say I shall want you then."

Jack went home very much stirred by what had been said to him.

After all, could it be wrong to go where he would do so much better? Was it not really his duty to accept the position? He could then drive the wagon instead of trudging wearily along the streets. They had never felt so hot and dusty as they did just now, when he might escape from the tiresome routine. Might, but how?—By the sacrifice of his pledged word; by selling his truth and his honor. So strongly did the reflection force itself upon him that when he told his mother of the offer he had received, he merely added, "It would be a grand good thing if I could take it, wouldn't it, mother?"

"Yes, it would."

"Some boys would change without thinking of letting a promise stand in their way."

"Yes, but that is the kind of boy who, sooner or later, is not wanted. It is because you have not been that sort of boy that you are wanted now."

Jack worked away, doing such good work, as he became more and more accustomed to the situation, that his mother sometimes wondered that Mr. Hill, who seemed always kindly interested in him, never appeared to think of raising his pay. This, however, was not Mr. Hill's way of doing things, even though he showed an increasing disposition to trust Jack with important business.

So the boy trudged through the three years, at the end of them having been trusted far more than is usually the case with errand boys. He had never forgotten the offer made by Mr. Lang, and one day, meeting that gentleman on the street, ventured to remind him that his present engagement was nearly out, adding, "You spoke to me about driving the wagon, sir."

"Ah, so I did; but you are older now and worth more. Call around and see me."
