"How do you know he is chummy with Ditson?" he asked.
"I have seen them together!"
"That means something!" cried Rattleton, excitedly.

"I will!" exclaimed Frank. "Ditson is treading on dangerous ground. If he makes a break, I'll descend on him. I have been easy with a chap of his treacherous nature quite long enough."
"Too long!" burst fiercely from Diamond. "If I had been in your place I'd ended Mr. Ditson's career long ago."
"I don't know what the fellows can do to injure me," said Frank.
"They'll find some way to give it to you if you don't watch out," said Rattleton. "Perhaps one of them hired that fellow to lame your horse."
"Perhaps so."
