Jack's heart gave a mighty thump. At last he was at one of the important stages of his long trip. As the riders advanced there came, from out of the fast gathering darkness a command:

"Halt! Who comes?"

"Friends!" exclaimed Mr. Hardy.

"What word have you?"

"Pine tree and moss agate," was the answer.

"You may enter," the unseen speaker added.

There was the sound of a heavy gate swinging open, and following their guide the boys urged their horses ahead. They found themselves on a well-made road, which led to a fairly large house.

"Dismount," said Mr. Hardy, as he brought his steed to a halt in front of a large piazza that surrounded the residence. "We are here at last."

As he spoke the door opened, sending out a stream of brilliant light.
In the center of the radiance stood a tall man, looking out.

"Good evening, Mr. Tevis," spoke Mr. Hardy.
