PLATE I.SUBMARINE DIVER'S COMPLETE OUTFIT. Described in Easy Science in this, and succeeding numbers. On referring to these separate parts and to the descriptions which will follow, an actual knowledge of their uses will be gained. In the early part of this century very little was known about deep-sea diving in armor. In 1839 the helmet and armor were first used, but since then great improvements have been made. To-day a suit consists of: Rubber and canvas suit, socks, trousers and shirt combined, copper breastplate or collar, copper helmet, iron-soled shoes, and a belt of leaden weights to keep the diver under water. The Diver's Helmet is made of tinned copper and contains three circular glass plates. One is at the front, and one at either side. All are protected by strong guards. The front eyepiece screws and unscrews. By this means the diver can give and receive instructions while above water, without having his helmet removed. In order that the air made impure by his breathing may escape, an outlet valve is placed at the back or side of the helmet. Fresh air is supplied through an inlet valve located in the back of the helmet. When the air is pumped through the compressor located above the surface, it opens the inlet valve and pure air is forced through channels to several points inside of the eyepiece. By thus directing its course, the diver is supplied with fresh air at all times and the glass is not dimmed by the bad air resulting from breathing. The helmet and breastplate weigh over fifty (50) pounds. (Will be continued in next seven numbers.) Young folks are not much concerned about adver- A firm believer in the little newspaper wrote: "With such a valuable medium as THE GREAT ROUND WORLD, you ought to pay your expenses out of advertisements alone." Many have expressed themselves to the same effect. It would be agreeable if wishes were realities. They have not reached that point. No effort has been neglected to secure reputable advertisements. THE GREAT ROUND WORLD'S solicitors have been capable and active. They had successful records on other papers. All that energy and capital could do since February 16 has been done. There are some things, however, that have not been done. Among them may be mentioned these: No dummy ads." have been printed to create the appearance of business. The circulation of the paper has not been misrepresented. Its bona fide subscription list has not been "padded." To do the subject justice requires space that cannot be spared, but it may be said that the little newspaper has refused a large amount of business because it would not insert a line that could in any way be detri- · mental to youth. That excludes such things as fake electrical appliances, bogus alleged cures for consumption, certain patent medicines, whisky cocktails, cigars, cigarettes, tobacco, and other things too numerous to mention. THE GREAT ROUND WORLD is conducted primarily in the interest of subscribers. It is not run chiefly as a vehicle to convey advertisements. Some day advertisers will grasp the chance to offer their wares in a clean paper, without axes to grind, which is appreciated by thousands of clean people. Great Britain at Kaulung CURRENT HISTORY (May 25, 1899) 717 Great Britain at Kaulung.-England has been taking active steps to protect her interests in the land lying back of Hong Kong. This land was obtained from the Chinese by a lease signed in 1898. Great Britain wished to have possession of the mainland back of the island of Hong Kong that she might fortify it and protect herself from the incursions of the other powers who now dispute her supremacy in China. She therefore leased from China for a period of ninety-nine years four hundred square miles, including the port of Kaulung (kow-loon), the waters of Mirs Bay and Deep Bay, and the island of Lan-tao. The natives were not, however, willing to allow the British to occupy the land which they had leased, and resisted with determination their attempts to do so, driving off surveying parties, and assuming a hostile attitude generally. The British immediately sent an expedition into the new territory to overcome the natives and force them into submission. On May 15 they despatched a large force into the Hinterland to punish the rebels, and on May 16 took the city of Kaulung. The British cruiser Undaunted, with four gunboats, was sent from Hong Kong to aid the troops by occupying Mirs Bay and cooperating with the land forces. A despatch dated May 17 stated that the troops are finding no difficulty in quelling the native, and the |
