"Assuredly," insisted Captain Hardy. "I think that you have learned enough to enable us to locate this hidden station. Go on."
Henry proceeded with the story of his search in the dark, of his uncertainty as to what he should do, of his fear of missing the message as well as the car, and of how he had intercepted that message, marked the fence post, and located the home of the automobile driver.
"Why, Henry," cried Captain Hardy, when the recital was ended, "whatever put it into your head that you had failed? You have done well—exceedingly well."
"But I didn't find the hidden station, and you said that was so important."
"That is a mere detail, Henry. We shall find it easily enough. We have our experience at Elk City to direct us."
"That's just why I felt so bad," said Henry. "If these Germans have concealed their wireless plant as skilfully as the dynamiters did at Elk City, we may never find where it is."
"We'll try before we give up hope," said the captain smiling. "And even if we never find it, we now know something more important than the location of one of their several wireless plants. We know where another member of the gang lives. That is excellent, Henry, excellent! The Chief will be more than pleased. I know he is a great deal more concerned about this wireless situation than he permits us to think. The public is clamoring for protection for the troops and the Chief simply cannot accomplish one-fourth of what is demanded of him. If we uncover this gang for him, we shall do a very real service to America, boys."
"We'll do it," cried Willie vehemently. "We'll do it. We'll get 'em just as sure as we got the dynamiters."
"I believe we shall," smiled the captain. "And if that's the way you all feel about it, I know we shall. We're closing in on them fast. To-morrow we'll go out to that field Henry has marked and see what we can find in the daylight."
So it happened that the succeeding forenoon found the five members of the wireless patrol rolling rapidly toward the point of investigation, in a motor-car furnished by the secret service and driven by one of its agents. Henry sat beside the driver and pointed out the way, while the others crowded into the rear of the car.
