“Um—let’s see,” and Captain Wiggs who, followed by the boys had gone to the main cabin, began thumbing over the pages of a small book he took from his pocket. “‘Proceed to’—no, that’s not it—‘take cargo’—um—no, it must be on the next page—Oh, yes, here it is. ‘Get cargo of grain at Lakeville, from Robert Hayward Company.’ That’s it. The grain belonged to Robert Hayward—why—er—say, boys, that’s the name of the man who was hurt back there in Darewell—he and his daughter Ruth—you know him—why, Fenn, he was at your house!”

“So he was!” exclaimed Fenn, his knowledge thus unexpectedly confirmed.

“Quite a remarkable coincidence!” went on the Captain. “Very strange! Well, strange things are always happening. You didn’t hear what started the fire, did you?”

“I heard a policeman say it was spontaneous combustion,” said Frank, “but they always give that as a cause, when they can’t think of any other.”

“I don’t s’pose they’ll ever find out,” remarked the captain. “Well, I can’t do anything more. We’d better turn in, although it’s most morning. Soon as it gets daylight I’ll have to hustle around and find out what I’m going to do.”

Captain Wiggs was a very busy man the next day, sending messages to the steamer’s owners to ascertain their wishes. The boys visited the elevator, in which great piles of grain were still smouldering, in spite of the tons of water poured on them. Fenn kept a lookout for the mysterious men, but did not see anything of them.

Captain Wiggs had to remain tied up at Lakeville until he received orders to proceed to the next port for a cargo that would be awaiting him there. The boys spent the time on shore, visiting various scenes of interest.

“Well, we’re off again!” cried the commander, on the morning of the third day, as he came hurrying down the dock, waving a telegram in his hand. “Tying-up is no fun. You may get under way as soon as possible, Mr. Sidleton,” he added to the first mate.

Steam was up, and, in a short time the Modoc was again plowing the waters of Lake Erie. Gradually Lakeville was left behind, and soon they were out of sight of land.

“Ding-dong! Ding-dong! Ding-dong! Ding-dong!”
