to the garage.

Henry was about to ask Captain Hardy what he meant by saying that they
were sugar refiners, but when he saw the motor-cycle that awaited him
he forgot his question and gave a sharp cry of exultation. It was a
beautiful machine, with tires so strong and thick they were practically
puncture proof and were evidently equal to any demand that was likely
to be made upon them. Evidently the engine was one of great power.
The frame of the machine was a dark gray; and Henry instantly noted the
fact that there was an almost utter absence of nickel about the
motorcycle. The spokes, handle-bars, and trimmings were all enameled
black. The headlight was a powerful electric one, with a black cap
over the lens. With great interest Henry examined the spark- and
gasoline-controls, the motor itself, and finally the muffler, which was
of the most improved variety. He looked in the gasoline-tank and found
it full. The oil-tank was brimming. Every moving part had been
carefully greased and cleaned.

"What's this?" cried Henry, of a sudden, noting what seemed to be an
extra and unnecessary piece of framework.

"Take it out and see," said Captain Hardy, with a smile.

Carefully Henry examined the fastenings, to see how the extra tubing
was adjusted. Then he drew it forth.

"A metal cane," he said, puzzled. "What is it? What is it for?"

Captain Hardy explained. Then he picked up a small electric torch,
some well insulated wires that lay coiled on a near-by chair, and
something that looked like a giant fountain pen. He handed these
articles to Henry, and repeated what the secret service man had told
him as to their use.

"Put them in your pocket and be very careful that you do not lose
them," directed Captain Hardy. "Carry them with you so that you can
run to your motor-cycle at a second's notice. Now replace that cane on
the machine."

Henry slid the cane back and fastened it in place. It was gray, like
the car, and seemed to be a part of it. Then Captain Hardy fastened
the little map case above the gasoline-tank in such a way that Henry
could pluck out a map as he rode.

"Now," he said, "there is nothing to do but wait until the automobile
driver comes for another dollar. Then you must follow him wherever he
goes. You must watch every movement he makes. But you must not let
him see you. It's a hard thing to ask of you, Henry, for everything
hinges upon your success."

A look of determination f
