It was half past seven, and they had eaten their breakfast.  They had saved some for me, and I ate it, keeping an eye out for Snider.  He did not reappear, however, and after I had finished eating, I got “The Rifle Rangers” and went outside with it to read, and wait for the people who were coming on the steamboat.  I felt more comfortable outdoors than in.  With Mr. Snider creeping from one room to another I never knew what might happen, nor how he might try to cage me up.  Outside, he wouldn’t be able to touch me, if I had any kind of a start.

I had thought it over while I was eating breakfast.  There was some sort of hocus-pocus going on, connected with this excursion and the gold company.  Anybody could see that.  Whether they really expected Captain Bannister to come on the steamboat, or whether that was all a lie to make me stay, I could not tell.  Captain Bannister had said, according to the men at the Eagle House, that he was coming to Rogers’s Island, so it might be that the Professor’s story was true.  On the other hand, it might have been made up out of whole cloth in order to keep me there over night.  But why should they want to do that?  They thought I had seen something,—­the Professor had asked:  “What could he have seen?” I hadn’t seen anything,—­except that they were working over some boxes on the platform beneath the wharf.  They had both acted like boys caught in the jam closet.

I sat on the front porch, and thought it over, and read, and then thought it over again, until the smoke of the steamboat was in sight.  This must have been about half past nine.  The Professor and Mr. Snider had been out in the barn most of the time, or bringing chairs and putting them up on the platform in the side yard.  When the smoke of the steamboat appeared they both came around to the front of the house.  The Professor shook hands with me, and said goodbye.  He had to go to Lanesport, he said, on important business, and he must start now.  He was going by the road.

“Of course,” said he, “I wish I could stay for the excursion, but Mr. Snider will have to receive them, and explain the works.”

“And James,” added Snider, “will come around to the side and help me with the chairs,—­won’t you, James?  It will only take a moment.”

The Professor vanished around the corner of the house, as we turned into the drive.

“I hope you understand, James,” said Mr. Snider, “that any—­er—­ precautions we have taken since you came amongst us, were only such as were perfectly necessary under the circumstances.  We are guarding here, of course, a valuable scientific discovery,—­a very valuable discovery.  There are people who would give thousands of dollars, and go to any lengths to get our secret away from us.  Any lengths.  We are determined that these men—­these wicked men, I regret to say—­shall not steal from the Professor the fruit of his brain.  The workings of this—­er—­this precious secret
