"I met the Colonel three days ago when I delivered a letter from the Commanding Officer at Camp Pendleton. I am a marine, Señor."

"Why are you dressed as you are, if such is the case?" and the officer looked Dick over with suspicion in his eyes.

Briefly Dick gave his explanation, but before Diaz would consent to hear the rest of his disclosures the orderly was directed to telephone Frederico at the station to verify the statements.

Colonel Diaz was a graduate of an excellent military school in the United States, and his command was remarkable for training and discipline, and though Dick fussed over the delay, he nevertheless admired the native officer for his caution.

Dick now saw that he had erred in not telegraphing to have the train held at Nagarote until he could explain by wire to the marine officer in command all the facts in order to permit that officer to govern his future movements to better advantage. While thinking of this, Colonel Diaz entered the tent, having gone out in order to talk to Frederico in person.

"You are Private Comstock, guard for Sergeant Dorlan, special messenger for the American forces?" he stated in a questioning manner.

"I am."

"I will hear what you have to say. Step outside, orderly, and take the guard who brought this man here with you." Then turning to Dick, he said in a most agreeable tone, "Be seated, Señor, and proceed."

Dick now told of his two meetings with the German and Englishman, and of the conversation he had so fortunately overheard on each occasion.

"Do you mean to say, Señor, that these two gentlemen, Señors Schumann and Heffingwell, are the men you heard engaged thus?" asked Diaz in amazement.
