The Submarine Boys on Duty / Life on a Diving Torpedo Boat

by Victor G. Durham

By this time Jack Benson and Hal Hastings had had a good chance to see exactly what the interior of a submarine torpedo boat was like.

A level floor extended throughout the entire length of the "Pollard." Below this floor, reached by hatchways, were various small compartments for storage. Under the level of this floor, too, were the "water tanks." These were tanks that, when the craft lay or moved on the surface of the ocean, were to contain only air. Whenever it was desired to sink the torpedo boat, valves operated from the central room of the boat could be opened so that the water tanks would fill, and the weight of the water would sink the boat. In diving, the forward tanks could be filled first, and then, when the desired depth was reached, the other tanks could be filled entirely, or partly, in such a way as to control depth and position.

With the boat below the surface, and the commander wishing to return to the surface, compressed air could be forced into the water tanks, expelling all the water in them, or a part of the water, if preferred. The valves would then operate to keep more water from entering.

On the surface the "Pollard" was intended to be run by a powerful six-cylinder gasoline engine. When below the surface the boat was to be propelled by electric power supplied from storage batteries. Below the waves the gasoline engine could not be used, as such an engine consumes air and also creates bad vapors.

On the morning when our two young friends went to work the electrical engine was fully installed, and had been tested. The gasoline engine was in place, but the fittings had yet to be finished. In the course of this latter work the necessary connections were to be made between gasoline engine and dynamo.

The many strong-walled receivers for compressed air had been placed, and were now being more securely fitted and connected by the workmen. The final work on the compressed air apparatus was yet to be done by a special crew of workmen who were soon to come down from New York. A powerful, compact plant for compressing air was a part of this outfit.

Right up in the bow of the "Pollard" was the tube through which a Whitehead torpedo, fourteen feet in length, could be started on its destructive journey by means of compressed air force. One torpedo was to be carried in the tube, six others in special lockers on either side.

Back of the torpedo room was the rather cramped engine room in which were the gasoline and electric motors, other machinery and work-benches. Then came the central cabin, some twenty feet long and about ten feet wide. Here was a table, while the seats at the side could be arranged also as berths. Out of the cabin, aft, led a narrow passageway. Off this, on either side, were a narrow galley, cupboards, ice-box and toilet room. Nearer the stern were two compact state-rooms, one intended for two "line" or "deck" officers, the other for two engineer officers. There were other features about the "Pollard" that will be described as need arises.

For more than an hour the entire gang had been at work, though Joshua Owen had seen to it that Jack and Hal had nothing more to do than lift or hold heavy articles, fetch tools, etc. Still both boys stood this good-humoredly, paying strict attention to orders. David Pollard, watching them at times, and guessing how they might feel under such treatment, found his good opinion of the two newcomers still rising.

Stopping their work, when the order came, the workmen lighted their pipes. Jack and Hal, not liking the clouds of tobacco smoke, ran up the spiral staircase to the manhole, stepping, out upon the platform. As they did so they encountered a man of about thirty years of age who had just reached the platform deck from the shed flooring.
