“I’ll bite, but what do I shoot at?” asked Bob.

“I’ll pick out the fish and you shoot it,” said Sam.

He handed Bob the rifle and pointed to a fish near the boat.

“Get that one,” he said.

The fish was within four feet of the boat. It seemed to Bob that he could touch it with the muzzle of the rifle. He aimed at the fish and fired. Just where the bullet went was a mystery to him. The fish never even budged from its position. One thing was certain: he had not made a hit.

“I aimed right at that fish,” said Bob, “but never hit it. Are there any bullets in the gun?”

“Look at this one before you load,” said Sam as he handed Bob a cartridge.

Bob examined the cartridge. Apparently it was all right. Once again he aimed at the fish and fired. Another miss. Bill was just as mystified as Bob. There was no doubt that the bullet went into the water, but it certainly did not hit that fish.

“Let me try it,” said Bill.

Bob handed the rifle to Bill and sat down to watch the proceeding. Bill loaded the rifle and took careful aim. The boat was steady, so that there was no reason why he should not make a hit. He aimed right at the fish and carefully squeezed the trigger. He watched expectantly for the fish to show some signs of being hit, but it didn’t.
