"You infernal idiot!" he ground out savagely to Baker, as they moved away. "What do you mean? I'll punch your fool head when I get you out of here!"

But the plump young man merely smiled.

Halfway down the room a group of attractive-looking young men hailed them.

"Join in, Baker," said they. "Bring your friend along. We're just going to raid the commissary."

But Baker shook his head.

"I'm showing him life," he replied. "None but Fuzzies in his to-night!"

He grasped Bob firmly by the arm and led him away.

"That," he said, indicating a very pale young man, surrounded by women, "is Pickering, the celebrated submarine painter."

"The what?" demanded Bob.

"Submarine painter. He paints fish and green water and lobsters, and the bottom of the sea generally. He paints them on the skins of kind-faced little calves."
