Book Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1910 edition. Excerpt: ...I think I'll go to bed. I want to get up early, for there'll probably be something unexpected to do at the last minute. How about you, professor?"

The motor seems to work perfectly. That was my greatest anxiety. I will now proceed to generate the gas necessary to completely fill the bag. I suppose all three of you boys are coming along?" "Of course; and so is Professor Snodgrass." "That will make a nice party, and we will not have to carry so much ballast. Just go over all the cords, see that none are tangled, and test the wire stays and the braces. We don't want any accident to happen." The boys were a trifle nervous, now that the time was at hand for the great test. YVould the airship rise? Would she sail through the upper atmosphere--or come down like a stone? The big gas bag seemed to promise that at least they would go up, but whether they could advance, and whether the Comet would allow herself...
