At the top of the grade, he noticed, was a donkey engine which operated the cable that drew the car up from the dock, and at the top of the incline was a huge pile of material.
The car had been drawn up to the top of the grade by this time. There the engineer who operated the engine stopped it.
Just then the whistle blew for the noon hour. The men quit work and went to get their dinner pails, while the engineer started to draw the fire. Beside the engine, he began to chop some wood, while the car was held at the top of the grade by the cable.

In our pursuit we came at last in sight of a lonely hut. Evidently that must be a rendezvous of Del Mar. But was he there? Was Elaine there? We must see first.
While we were looking about and debating what was the best thing to do, who should appear hurrying up the hill but Del Mar himself, going toward the hut.
As we caught sight of him, Arnold sprang forward. Woodward and I, followed by the soldiers also jumped out.
Del Mar turned and ran down the hill again with us after him, in full cry.
While we had been waiting, some of the soldiers had deployed down the hill and now, hearing our shouts, turned, and came up again.
Beside his engine, we could see an engineer chopping wood. He paused now in his chopping and was gazing out over the bay. Suddenly he had seen something out in the water that had attracted his attention and was staring at it. There it moved, nothing less than a half-submerged submarine.
