“You nebber kin tell, Marse Tom,” Rad had said, shaking his woolly head, when Tom remonstrated with him, “w’en somebuddy might cum nosin’ an spifflicatin’ roun’ here w’en you’s busy wid yo’ wuk; an’ ef dey does, dey’s goin’ to fin’ ’Radicate Sampson right on de job. Nussah, nussah, Marse Tom, dey ain’t no use argifyin’. Ah stays heah while you stays heah.”

Koku was less voluble, but no less devoted.

“Me sleep when you sleep,” he said simply.

Faced with such loyalty, Tom could do nothing but surrender.

The days were no less busy than the nights, though in another way. Tom spent hours with Garret Jackson, the manager of the mechanical department of the works. He was a first-class mechanic, clear-headed and forward looking, and had been with the Swift Construction Company for years. Tom had not only the greatest respect for his ability, but also implicit confidence in his discretion. Again and again it had been necessary for Tom to entrust him with secrets of his inventions while he was having special machinery made, and he had never betrayed his trust. Repeatedly Tom thanked his stars that he had two such faithful coworkers as Ned Newton in the financial end and Garret Jackson in the mechanical part of his business.

As a result of his conferences with Jackson, it was not long before a high fence began to be constructed in a rather remote section of the plant. Many curious glances were cast at it as it went up, enclosing an area of about a hundred feet square. What it was intended for only a few knew, and the cold stare of Jackson when any one hinted at a question soon discouraged the inquisitive.

It was just verging on dusk one night, when Tom, coming back from the post-office, passed the one large confectionery store which the town of Shopton possessed. He glanced carelessly through the window and saw that the store contained two customers, a man and a girl. The latter, who was a trifle out of the direct line of Tom’s vision, was edging away from the man, who seemed to be annoying her. The man followed and laid his hand on her arm.

The girl threw it off and faced him indignantly. As she did so, Tom saw that it was Mary!

In a flash he was in the store.
