With a sigh of relief, the gambler began to pull the winnings toward him.

"Better look at the I O U," The Kid drawled, "and see that it's all right and proper." As he spoke, he tossed his cards carelessly toward the gambler, face down.

The youth in the green eye shade unfolded the paper and looked at the writing within. His eyes widened a little and he looked again, blinking. Slowly the following words swam into his consciousness:

Son, you can't gamble worth a cent, but rake in the money and follow me in five minutes. I'll meet you back of the saloon. I'm your friend, Harry Thomas, and your mother's happiness is at stake.

The gambler's face went a bit paler. Only his poker face kept the astonishment out of his eyes. Slowly and furtively he looked at the cards Kid Wolf had tossed away so carelessly. The Texan had held four aces!

CHAPTER XIV

AT DON FLORISTO'S

In the moonlight, behind the El Chihuahense Saloon, Kid Wolf and the gambler met. The latter found The Kid leaning silently against a ruined adobe wall in the deserted alleyway. The sound of the music from within the gambling hall could be heard faintly. There was a silence after the two men faced each other. Harry Thomas finally broke it:

"How did yuh know me? I go by the name of Phil Hall here. And who are yuh?"

"Just call me The Kid," was the soft answer. "I knew yo' by yo' one brown and one black eye."
