the platform, which ended to the southward in a sheer precipice of some hundreds of feet. There was a ledge to keep it from rolling over. Signor Davelli led us to this car and invited us to enter it.
There was plenty of accommodation for two or three people. There were easy benches and couches, and there were three boxes with distinctive marks like numbers on the lids. At the end of the car which was furthest from the ledge, the inside end, there was a great deal of machinery, but not of such a size as I should have expected considering the size of the car. This machinery consisted of two batteries resembling galvanic batteries in many ways, but the stuff used up in work was not fluid but solid; it consisted of large squares of matter, which I think was wholly or mainly metallic. The batteries were connected with a strong round bar, made, as I thought, of some sort of metal[1] running through the car and supporting a pair of huge paddles, or wings, one on each side of the car. At each end of the bar were certain little wheels and cranks, devised not so as to cause the paddles to revolve, but so as to give them a wing-like motion. At the forward part of the car were several vessels of a form which suggested a chemical apparatus for generating gas.
- ↑ I discovered afterwards that it was not metallic.
