"Thank goodness, they are off," cried Sam, with a sigh of relief, as the "Nimrod" began slowly drawing away.
Now, for the first time, the boys were able to enjoy the scenery, and talk about their plans for the day. Already, the fresh air had given them a decided appetite, and Tom Clifton agreed that at the proper time he would officiate at the oil-stove.
This decision had hardly been reached, and they were engaged in preparing a menu, when Bob, who was at the wheel, called out: "They are coming back, fellows."
This was quite true. The "Nimrod" was seen to describe a wide circle and head directly for them. On it came, at full speed, the engine making a loud and continuous roar.
Bob altered the course of the "Rambler" slightly. The helmsman of the other boat did the same, and they continued to near each other, both headed directly for the same spot.
It was at once evident that the reckless Nimrods had determined to annoy them by compelling Bob to change his course. Now the "Rambler," in spite of the fact that the "Nimrod" had beaten it, was, nevertheless, a speedy boat, and it thus happened that almost before they knew it the two craft were dangerously near each other.
"Stop, stop!" commanded Nat. "Don't you see where we are going?"
The sound of both engines ceased. Bob reversed his an instant later.
"Look out!" continued the commander of the Nimrods, frantically. "What is the matter with you? You're running us down!"
But the crash could not be averted. The side of the "Rambler" swung against the "Nimrod" with such force that Nat Wingate was almost pitched to the deck.
