up."

The fisherman who was called to, pulled out the switch, thus stopping
the motor, and the boat drifted about on the slowly rising and falling
billows.

"Can you see him?" asked the captain of the man who acted as mate.

"Yes, he's right astern, but that fish----"

"Is he coming after Jake?"

"Full tilt!"

"Grab that prod, one of you!" yelled the captain. "See if you can
harpoon him with it. I'll git out the duck gun, though land knows it
ain't much use against a pesky swordfish!"

One of the fishermen picked up the iron-shod pole the unfortunate man
had dropped as he went overboard, and stood ready to cast it at the big
fish, which could be seen swirling along in the water, near the swimmer.

"Say!" cried Blake to Joe. "It may seem a heartless thing to do, but why
can't we get some moving pictures of this?"

"We can," decided his chum. "We can't help any, and we might as well
film it."

"Come on, then. You hold the camera steady and I'll turn the handle."

They had a machine all in readiness, its tripod shortened so that the
lens could be brought close to the water.

"He's dived!" cried one of the men.

"Who--the fish, or Jake?" demanded the captain.

"Jake. He saw the fish coming at him, and he went under. Lucky he did,
or he might have been cut in two."

"Throw that prod; can't you? I'll have this gun ready in a minute."

The captain had pulled from a locker an old-fashioned, double-barreled
duck gun.

"It's loaded with slugs," he called to the boys, who were even now
taking moving pictures of the strange scene. "I carry it for sharks, but
it'll do as well against a swordfish, though they don't commonly attack
men."

"Here goes for a cast!" cried the man with the prod, which was a sort
of boathook without the hook. "I'll see if I can spear him!"

Leaning forward he threw the weapon with all his force. The other
fishermen, some of whom had grasped the spare oars to swing the boat
around, looked eagerly to see the result.

"Missed, by ginger!" exclaimed the captain. "Here, let me try. Where's
Jake?"

"Out there. He's swimming strong," was the answer. "The pesky fish is
coming back at him again."

"Duck, Jake, duck!" cried the captain, as he got ready with the gun.
"I'm going to shoot. Get down out of the way, and hold your breath.
We'll have you in another minute!"

He could see the swordfish plainly now, rushing directly toward the
swimmer. The man heard and followed directions. Dee
