“You may be right,” Don replied. “We’ll have to keep our eyes open for them in the future.”

After supper the boys continued the cruise, sailing for a time and then, as darkness came down, using the motor. Jim put on the lights and Terry asked concerning them.

“The green one is the starboard light,” Jim said. “The port is the red one. The danger side of a ship is the port side; the watch has to be keenest there. The easiest way to remember which is which is to think that port wine is red, and then you can always remember that the port light is the red one.”

Two miles off shore, on a lonely section of the coast, the boys lowered the anchor and prepared to spend the night. Terry, who had looked forward eagerly to his first night on the water and his first sleep in a bunk, was disappointed to find that they intended to sleep on deck.

“You can sleep inside, if you want to,” Don told him. “Only, I think you’ll like it better sleeping out on deck, under the stars. If we have stormy weather—and I think we are going to, because the barometer is going down—you’ll sleep indoors quite enough. But suit yourself.”

Terry decided that he would sleep on deck, and they accordingly carried the blankets out on deck and spread them out. As it was too early to go to sleep yet, they talked for a time of general subjects.

“Suppose a storm, like a fog, comes up in the night?” Terry asked.

“Well, we can go close to shore, or anchor out, but if we anchor out, we’ll have to toll the bell all night. If anyone feels particularly like sitting up all night and pulling on the rope, they are perfectly welcome to do so.”

“Count me out,” Terry decided. “We might use Jim, however.”

“How is that?” Jim asked, suspiciously.
