It is necessary, however, to consider what other nations have done in connection with the submarine, long before the Holland was adopted by the British Admiralty. A Swedish inventor, Dr. Nordenfeldt, who had given a great deal of attention to the subject, was attracted by Mr. Garrett’s method of what was called “bottling up” the steam engine, so as to permit of the vessel diving under water. The first Nordenfeldt was cigar-shaped and 64 feet long, and was remarkable in one respect, for she was the first to carry a tube for discharging Whitehead torpedoes. She underwent in the presence of Royalty a fairly successful trial on the first day, and was ultimately purchased by the Greek Government. In 1887 Dr. Nordenfeldt and Mr. Garrett designed boats with screws placed on top, for regulating the ascent and descent, and the torpedo tube of each was carried at the outside of the bow instead of inside. One of these boats was taken by Mr. Garrett to Constantinople, where she was put through numerous evolutions in the presence of the Sultan himself and the greater part of the population of that city. The engineer and Mr. Garrett understood their work perfectly, but the same could not be said for the Turkish crew who were told off to be drilled in its manipulation. They knew nothing of submarines and did not want to learn, and maintained their obstinacy to the utmost. The trials took place in June, 1887. The Turkish boatmen simply would not keep out of her way, until one of them navigated his empty barge too close to the Nordenfeldt, whose revolving propeller knocked such a large hole in the barge’s bottom that it was as much as the boatman could do to get it to the shore to save it foundering. After that the Nordenfeldt was allowed more room. The first time, so far as navigation was concerned, she was tried she was a success, but directly her stability was altered by the discharge of her Whitehead torpedo from the bows, her trim was changed very materially, and it was even thought possible that she might go down stern first. However, the Turks bought her and added her to the collection of naval purchases of which they could make little use. A later submarine was built by Nordenfeldt, but proved no more stable, horizontally, than the other. It was purchased by the Russian Government, and was lost on the way to the Baltic.
The French have seemed to find an extraordinary fascination in submarine navigation. It was very great before Jules Verne published his fascinating romance, “Twenty Thousand Leagues Under the Sea,” and became even more enthusiastic than ever. Of the early French experiments it is not necessary to say much. One of the first of the reliable French submarines was the Goubet, 10 feet in length, 6 feet high and 3 feet wide. This vessel was succeeded in the estimation of the French naval authorities by the Gymnote, which proved as remarkable a forerunner of a type as the Dreadnought did of the new type of battleships, and, like the Dreadnought, she has been steadily superseded by improvements upon her design. The Gymnote was designed by M. Gustave Zédé, although the credit of suggesting her in the first instance is sometimes ascribed to M. Dupuy de Lôme. She was launched in September, 1888, and was cigar-shaped. She displaced about 50 tons with dimensions of 59 feet in length, 6 feet in depth, and 5 feet 7 inches in breadth, and her electrical motor was supplied with the necessary power from a large installation of accumulators. Her conning tower was telescopic, and she had a periscope to enable her commander to take observations without coming to the surface; she was one of the first vessels, if not the first, to be fitted with a periscope or optical tube, the principle of which is that a mirror placed at a certain angle above the tube has its reflection reproduced by another mirror placed entirely parallel to it at the bottom of the tube. She carried two Whitehead torpedoes. M. Zédé planned another submarine which was launched in June, 1893, and its electrical installation nearly poisoned its crew owing to the fumes given off. Another Goubet followed, but was so slow that the Government rejected her. Since then, especially in the last few years, the French Government has gone in for a singular variety of these vessels. Some of them have undergone marvellous tests with conspicuous success. But none have attempted such a feat as two British submarines have accomplished, viz., from England to Hong Kong. They were towed part of the way, and escorted all of it, but their own power was not allowed to be idle.

It is now attempted to propel French submarines by Diesel engines for surface work, and by electric motors for underwater work; the result of the experiment is not known at the time of writing.
The Russian Government is said to favour submarines of the Lake pattern, so named after its American inventor, of which a great deal is thought; and America is said to have adopted both Holland and Lake submarines. One Lake boat was provided with wheels, and went on a submarine motor tour along the New England coasts, and Mr. Lake finally offered to demonstrate the usefulness of his vessel by finding and cutting the cables of the mines protecting one of the American ports. This was more than the American Government could allow, so he had a cable laid across a harbour mouth, and having found it, severed it.
