"Tell Ike to get the horses and saddle them at once—three of them," he ordered when the servant appeared. "Tell him to stop and get Carlito, and have them all here as soon as possible."

"Come on, boys—Phipps says he's just starting. He says he telephoned for Dr. Rivers but he isn't home. What'll we do in case either of them is badly hurt?"

"We fellows ought to put our learning into practice," spoke up Fred at once.

"Yes, we'll take our emergency kits," said Jerry.

"I doubt if you can do anything," replied the captain, as they left the house. "You haven't had any practical experience yet."

"We'll do anything we can for Herb," responded Jerry warmly.

"Why not get Dunk?" suggested Fred. "He was the best of the bunch, his father being a doctor."

"All right," agreed the captain, swinging into his saddle, just as Carlito dashed up.

"What's the matter?" he asked, breathlessly.

They told him the situation in a few words.
