"He's just the chap you want!" nodded Jack, with satisfaction. "Put Nemo into the Bethany races, and let Toots ride him."

"I'll think of it," said Frank.

A hostler approached the group.

"Howdy do, Mr. Merriwell, sir?" he said. "One of your friends called to see your horse this morning, sir."

"One of my friends?" cried Frank, in surprise. "Who was it?"

"He gave his name as Diamond, sir—Jack Diamond."

Merriwell immediately turned on Jack and asked:

"Hello, how about this? Did you call to see Nemo this morning?"

"Not much!" exclaimed Jack. "This is the first time I have been here. The hostler is mistaken."

"You must have misunderstood your visitor, Grody," said Frank. "He could not have given his name as Jack Diamond, for this is Jack Diamond here."
