"Boys," Will exclaimed, "this is Frank Disbrow. He started for our cabin in company with Bert Calking, the boy we found on the floor last night. The two were bringing a code despatch to me, and they became separated early yesterday morning."

"A code message, was it?" Tommy asked.

"Yes, a code message," Will answered, "but the bearer of the despatch may, for all we know, have been forced to translate the message for the benefit of the man who robbed him of it."

In a moment Frank was by the side of his chum, gazing down into a white and haggard face. He turned away in a moment with a little shiver of anxiety. His face, too, was pale.

"I'm afraid that's a serious wound!" he said.

"If we only had a surgeon," Sandy suggested.

"I'll go get one," offered Tommy. "I can cut across to Katalla in no time and bring back the best doctor there is in the country."

"I'll go with you," offered Sandy.

"Now, wait a minute, boys!" Will said in a moment. "Let's think this matter over. If you go to Cordova instead of Katalla, you can communicate with Frank's father at Chicago, and so get in touch with Mr. Horton. In this way, we can learn the contents of the code despatch. There surely was some strong reason for sending it, and it seems as if we ought to know its contents."

"That's a good idea, too," exclaimed Tommy. "We'll go to Katalla, and perhaps we can find a boat about ready to sail for Cordova. In that case we ought to get up to the wireless station and back in a couple of days. The distance isn't great, but it's rough traveling."
