"All right, me lad, and if those hounds in the yard nab me, you must do something to distract their attention."

"I'll attend to them," replied Jim confidently.

"Here goes, then," said the engineer, and with the liveliness of a cat he was up and over, and Jim followed.

"Now," exclaimed the engineer, "we are in for it. What is our next move?"

"Take in this rope," replied Jim practically; "maybe we can use it in our business."

His friend patted James on the back to show his appreciation. Then they together got most of the vine down, and Jim made a neat coil of it. Then before they went on they waited, listening for any sound that might indicate life of any kind about the castle, but it was absolutely dark and silent.

In all probability the dogs were somewhere about, or at least one of them would surely be on guard. Jim knew that the first thing to do was to locate these hounds, for if they were to get on their trail the game would be up, aside from the danger of being attacked by these ferocious beasts, who were in reality as strong as a mountain lion and much more courageous.

First they must find some sort of shelter. The enclosed yard was a large one, including about eight acres, with trees and shrubs set here and there and a fountain in the center of the driveway. This latter they would hardly use, unless they needed a bath. Where the two comrades had got over the fence was on the north side of the house, and about one hundred and fifty yards distant.

At half the distance to the house was a clump of bushes in the center of which rose a tall tree. Back of the castle a short space was a stable built of brick. At first Jim thought of making it his base of retreat and observation but gave it up for the present as he was fearful that one of the dogs might be there or chained near it. As a matter of fact, one of the big hounds was lying with his nose to the ground not far from the double door of the stable. It may as well be stated that this building was at the foot of a sharp slope below the castle and its back wall was built on a line with the bluff.

"Come on, John," said Jim finally; "we will make for that clump of bushes with the tree in the center."
