For, true to the arrangement Tom had made with the railroad people, another reassuring telegram was brought to him before bedtime. The second conductor responsible for the management of the Western bound freight to which the Hercules 0001 was attached, sent back a brief statement of the safety of the electric locomotive.

Naturally the two chums would have passed the freight and got well ahead of it before reaching Hendrickton. But Tom had business in Chicago, and they stayed over in that city for twenty-four hours. The freight train went around the city, of course. But the telegrams continued to reach Tom promptly, even at the hotel where he and Ned stopped in the city.

Occasionally the trainmen in charge of the freight mentioned Koku. His eccentric behavior doubtless somewhat puzzled the railroaders.

"That's all right," chuckled Ned. "Let them think Koku is dangerous if they want to. That O'Malley person believed he was!"

"I'll say so!" replied Tom. "The way he ran when Koku started after him that time on the Waterfield Road seemed to prove that he didn't want to mix with Koku."

Heads were poked out between curtains all along the aisle and a chorus of more or less excited voices demanded:
