"I am positive that the Dawsons and Ridgely have made for some
obscure point, probably near Lake Superior, and will open up
business in the old way, do their work only at night, and I have
come on here to ask Dashaway to work in harmony with me."

"Most certainly he will," pledged the factory manager.

"I am after Ridgely, you are after your aircraft. We can work
together," pronounced the officer. "I intend to start at once for
the Lake Superior district. I shall set my men at work clear along
the line and over the border, to try and find a trace of my man. I
haven't an airship, though, you must remember, and wouldn't know how
to run one if I had. That's where you come in, Dashaway. You
search the air, I'll watch the land. What I want to do is to give
you a list of points where I or my men can be reached at a moment's
notice any time. If we keep in touch with each other, I believe we
can land those rascals."

For over an hour after that the officer and Dave had an earnest,
confidential chat together. Mr. Price brought out maps, and gave
Dave great deal of information as to the smuggling system on the
border. In the meantime, Randolph and Hiram again visited the
aerodrome. After the revenue officer had departed, Dave came across
Hiram looking for him.

"Say, Dave," exclaimed the excited youth, "it's like a new world to
me, all this. I declare, I never had such a time in my life. This
Mr. Randolph is a prince."
