If, for example, there should be a deposition of moisture upon the silk, and the machine begins to descend in consequence, there will be no necessity for discharging ballast to remedy the increase of weight, for it is remedied, or counteracted, in an exactly just proportion, by the deposit on the ground of just so much of the end of the rope as is necessary.
We steered due West ; but as the trailing of the buoys materially impeded our progress, and we had the balloon abundantly at command, either for ascent or descent, we first threw out fifty pounds of ballast, and then wound up (by means of a windlass) so much of the rope as brought it quite clear of the sea.
At noon, to-day, ascended to an elevation of nearly 25,000 feet, by discharging ballast. Did this to search for a more direct current, but found none so favorable as the one we are now in.
The car of the balloon was small and neat, some bags of ballast the untidiest of its contents, and he had found a light folding-table and put it at his elbow, and on that was a glass with champagne.
"Ballast!" he cried, and seized a little sack from the floor, and heaved it overboard.
He sent out quite needlessly a third sack of ballast and a fourth, and presently had the immense satisfaction of soaring up out of the damp and chill into the clear, cold, upper air in which the day still lingered.
He found himself drifting down towards a mono-rail line, and hastily flung out two or three handfuls of ballast to clear it.
He threw out a bag of ballast, and was astonished to find himself careering up through the air very rapidly.
We rigged up a single short mast and light sail, fastened planking down over the ballast to form a deck, worked her out into midstream with a couple of sweeps, and dropped our primitive stone anchor to await the turn of the tide that would bear us out to sea.
While we waited we devoted the time to the con-struction of an upper deck, since the one immediately above the ballast was some seven feet from the gunwale.
As for my boat, it could not have been kept afloat but for the extra ballast. I sat cocked over the weather gunwale, tiller in one hand and sheet in the other; and the sheet, with a single turn around a pin, I was very often forced to let go in the severer puffs.
Then a couple of seas filled it, and it sank straight down, dragged to bottom by the heavy ballast. So quickly did it all happen that I was entangled in the sail and drawn under.
