Weight, of course, was the great bugbear of every air-ship inventor, and the chief problem was to provide a motor light enough to furnish sufficient power for driving a balloon that had sufficient lifting capacity to support it and the aeronaut in the air.

The islanders thus used for experiment were to some extent picked men, as none but able-bodied persons would have been selected for employ, and as they were, moreover, (he states,) accustomed to lifting burdens, and better-fed than the majority of their countrymen.

Our ordinary way in and out of the place is by the door of the outer office leading into the corridor, and we first pass through the usual lifting flap in the barrier.

Its quadruple floats, each the size of a tugboat and each capable of being exhausted of air, constituted a potential lifting-force of enclosed vacuums that very largely offset the weight of the mechanism.

At a given signal from the foreman, two operatives, stationed at each of the forty lifting points, with crowbars inserted in the holes provided for the purpose, give the screws a simultaneous turn in the same direction.

This lifting process had, very fortunately for the craft, been effected by an application of force from below, in a wedge-like manner, and by bringing the strongest defences of the vessel to meet the power.

It could not, we fancied, be by the front door of a shop which we saw beneath; it could not, we were certain, be through a window above, for whilst there was a pulley roller in front of it there was neither rope nor block visible for regular lifting purposes; neither, we thought, could it be through a large double- door at the side, for that was bolted, and seemed to have been made for something taller and broader than the human form.

Then he turned a cold eye on Serge and burst into a torrent of Bulgarian, under which Serge stood with lifting scalp.

So we took ship and travelled over the lifting sea, and remembered not things done in the towns we knew, but laid away the thoughts of them like soiled linen and put them by, and dreamed of Babbulkund.

Within this compass too, come those that are too much wedged into the world, and have no lifting thoughts above those things; that call to thrive, to do well; and preferment only the grace of God.

Lifting apparatus for screw propeller.

For it came to him with the clear simplicity of a child's vision that the process of attuning his being to the right note must inevitably involve suffering and pain: the awful stretching of the string, the strain of the lifting vibrations, the stress at first of sounding in harmony with all the others, and the apparent loss of one's own little note in order to do so...
