Bart sat into the game immediately, but, to the general surprise, Frank declined.

"I am short, and I don't feel like playing to-night," he said. "I've got a book I want to read, and it wasn't possible for me to have a light in quarters, so I came along."

He declined all offers of money, and sat down to read the book. He turned his back to the table, so the light fell on the pages from over his shoulder, and in a short time he seemed too much absorbed in the book to observe anything that was going on.

The game became very warm. It was without limit, and Hodge lost from the first. Both Gage and Snell were winning steadily.

Still Merriwell seemed to read on calmly. But he was not reading a great deal. In the palm of one hand he had a small mirror concealed.

By the aid of this mirror, he was watching the movements of Gage and Snell.

And he was making some very interesting discoveries!

At length there came a large pot. Hodge and Gage stayed in and raised till every one else fell out. Hodge took one card; Gage, who was dealing, took two.

Then there was betting such as had never before been known in that old boathouse.

Hodge's face was pale, and he refused to call, for he believed his time to get square had come. He put in his "paper" for more than fifty dollars, after his money was exhausted.

Finally the game came to an end, and Gage proclaimed himself the winner.

He started to take the money lying on the table. Like a leaping tiger, Frank Merriwell came out of his chair, whirled, thrust Leslie's hands aside, and pushed the money toward Bart.

"Not this evening, Mr. Gage!" he said. "I am onto your little game, and it won't work any more with this crowd!"

The boys sprang to their feet.

"What do you mean?" asked Gage, hoa.r.s.ely, his face very pale.

"I mean that you are a sneak and a cheat!" said Frank, deliberately.

"I mean that you are too mean and contemptible for any honest fellow in this academy to ever have anything to do with! I mean that you have deliberately robbed your companions by means of crooked appliances made for dishonest gamblers! That is exactly what I mean, Mr. Gage."

Leslie gasped, and managed to say:

"Be careful! You will have to prove every word, or----"

"I will prove it! I have been watching you, and I have seen you repeatedly make the pa.s.s that restores cut cards to their original position. I have seen you hold back at least three of the top cards in dealing, and give them to Snell or take them yourself. Those cards will be found to be skillfully marked, and that pack is short. Boys, count those cards!"

The cards were counted, and the pack proved to be four cards short.

"Here is one of the gambler's appliances of which I spoke," said Frank, thrusting his hand under Leslie's side of the table and wrenching away something. "It is a table hold-out, and it contains the four missing cards. This is the kind of a fellow you are playing cards with, gentlemen."

The faces of the boys were black with anger, Wat Snell being excepted.

Seeing his opportunity, Snell quickly slipped away, and before he could be stopped, had bolted from the boathouse.

Gage took advantage of the excitement to make a break for liberty, and he, too, got away.

"What a howling shame!" said Harvey Dare, in disgust. "We'd tar and feather them both. Anyway, they'll have to get out of the academy."

The boys who had put money into the game were given what they had invested. The rest was turned over to Hodge. It made his losing nearly square.

"This settles me," he said, grimly. "I am done playing. No more of this business for me."

"Stick to that, and you will be all right," said Frank Merriwell, in a low tone.

Leslie Gage knew what must follow. The story was bound to spread among the cadets, and he would find himself scorned and shunned. He immediately ran away, and it was reported that he had gone to sea.

Wat Snell had not the nerve to run away, but he found himself the most unpopular fellow at the academy, shunned by the cadets generally, and regarded with contempt.

The exposure of Gage's crookedness broke up the poker parties for that season, at least; and Frank was happy, for he had saved himself and rescued Hodge and Hans Dunnerwust.

But he was happiest in receiving the approbation of Inza Burrage, who learned, through her brother, what Frank had done.

CHAPTER XIII.

THE "CENTIPEDE" JOKE.

"Sh!"

"What's up?"

"There's a carmine haze on the moon."

"That's clear as mud! What's the racket?"

"You room next to Mulloy and Dunnerwust?"

"Yes."

"Well, you will hear the racket just about the time taps sound."

"But I want to know what's up," persisted the second speaker, whose curiosity was aroused. "Has somebody put up a job on those two marks, Mulloy and his Dutch chum?"

"You've guessed it."

"Who?"

"Guess again."

"Merriwell."

"Right. Take your place at the head of the cla.s.s."

This hasty and guarded conversation was carried on between two plebe cadets who had met in a corridor of the academy "c.o.c.kloft." The first speaker was a jolly-faced little fellow, whose name was Sammy Smiles, and whose companions had failed to invent a nickname for him that fitted as well as his real name--Smiles.
