"We hit her!" said Beany at the rail.

The Firefly, with every ounce of steam on, dashed ahead, doubling here and there and darting about like a frightened hare. A spot of oil appeared on the water.

"Something wrong," said Porky; "but you can bet we are slated to get right out of the immediate vicinity of here at our earliest convenience!"

The Captain, on the bridge, was talking earnestly with Colonel, Bright and the other officers. Every face held a look of almost incredulous relief. The gunners stood close to their steel charges, every man ready for instant action. The Firefly raced ahead, on and on. No one thought of the interrupted meal. No one thought of anything but the danger so narrowly passed. They were still far away from the danger zone. It had been a most unexpected attack.

No one noticed when the sun went down or when dusk fell. Not until darkness wholly hid the sea did they turn from their sea-wide search for approaching danger.

Then the Captain came down from the bridge and approached the boys.

"How did you happen to discover the periscope before the lookout did?" he asked.

Porky spoke for his brother. "It's his eyes," he said. "You see, sir, he has what they call abnormal eyesight. He can see farther and clearer than anybody else. He can see in the dark too, nearly as well as by day. So it wasn't the fault of the lookout that Beany saw it first. He always sees everything before anybody else gets a chance."

"That's odd," mused the Captain. "Well, young fellow, you saved the ship this time all right. It looks as though you had better be stationed on deck when we reach the danger zone. Come down now and get you supper. You never want to go into danger when you are hungry." He slapped Beany on the back and passed on.

The boys followed, suddenly conscious that they had omitted the important ceremony of dinner, but Beany was almost too nervous to eat. He felt as though those keen eyes of his should be on deck. There was a great clatter at the table, the Captain alone sitting in his usual serious silence.
