"Yes."

"I'll have to give him a more detailed examination. I'll admit him as a patient to my own hospital if you people will be responsible for him."

"That's all right, Doctor. Do what you can for him and send the bill to us," said Frank promptly.

The doctor rang a bell. An attendant appeared, wheeling a long, white table. Captain Royal was placed upon it and wheeled away.

"I'll let you know in the morning," promised the doctor. "Frankly, I don't mind telling you he's in bad shape. He may never regain consciousness again."

The boys were sobered by the thought that Captain Royal, for all his eccentricities, might be dying as a result of his wild dash over the rocks. Slowly they filed out into the street, bade good-bye to Mr. Jacobson and thanked him for his assistance, then went home. As Chet Morton lived out in the country, the Hardy boys invited him to spend the rest of the night with them. He accepted the invitation gladly, for the prospect of a long trip out of the city had not appealed to him. Biff Hooper, who lived near by, went to his own home.

The house was in darkness when they arrived, so the Hardy boys and Chet quietly parked their motorcycles, slipped up the back stairs and were soon in bed. They were so tired after their adventures of the day that in spite of the temptation to discuss matters, sleep soon overcame them.

CHAPTER XXIV

At the Hospital

Next morning, refreshed by their sleep, Frank, Joe and Chet were downstairs early, but not earlier than Fenton Hardy, who was already busy in his office clearing up some work before breakfast. He welcomed them cheerily.
