September, 1910 14 tons register, 50.5 ft. long, 15.7-ft. beam and 3.8-ft. depth. She is a dead rise model, a popular model because of cheapness of construction, and is driven by a 30-h. p. Regal motor. There is also a large number of gaso- line auxiliary craft on the bay and of these the majority are "buckeyes," or, as they are commonly called, "bugeyes." These craft, with their leg of mutton sails, are easily handled by two men and they ate ideal for general freighting, being swift in light airs and capable of carrying sail a long time when it blows. For their. tonnage they are much easier handled than a schooner would be and they are preferable because of this. A splendid type of the "buckeye" is the Emma, an auxiliary that finds em- ployment all the year around. In the months from September until the latter part of April she is in the oyster bus- iness as a buy boat, in the spring and summer she runs fish and after that she runs grain, so that she has no idle time. The power yawl has become a most important feature during the past couple of years. Vessels of 15 tons or upward with auxiliary engines are compelled, by law, to carry licensed pilots and en- gineers. Besides that it has been found that a four or five-h. p. engine in a 'TAE MarRINE REVIEW yawl will push a big vessel faster than a 10 or 12-h. p. engine in the larger craft. That not only. means the doing away with the licensed men, but it also means the saving of much fuel. More than that it gives the use of the small boat for the usual purposes, saving row- ing for the crew. When not in use, these power yawls are either carried on davits across the sterns or are slung on deck and they are no more in the way than an ordi- nary boat would be, the difference in weight being but little consequence. When the wind drops, it is the work of but a few minutes to sling the yawl over the side, tuck its nose under the counter, or to hold it alongside, and let it chug away, pushing the bigger boat along at least two miles an hour, all of which counts in the long run. Although the Maryland dredger can- not use an engine to propel his craft to, on «or from 'the. "rocks," he has found 'use for the gasoline engine, em- ploying it to wind in the dredges. There are at present fully 100 dredgers so equipped and everyone of them have proven to be successful, not only making larger catches, but saving money. One of these dredges will do the work of four men and do it better, quicker and cheaper. Latest Argentine Battleships (Translated by The Navy from La _ Nacion, Buenos Ayres.) HE normal displacement under a ordinary conditions is 26,500 tons, but the trial displacement with all weights complete and 1,600 tons of coal (40 per cent of the total) willbe 27,500 tons.* This large displacement will make the vessels very seaworthy and insure them a' high offensive and defensive efficiency; such displacement being in accordance with the latest types under construction, the Arkan- sas and Wyoming 'of the ' United States navy, of 26,000 to 26,400 tons; the Hercules and Colossus of the British navy, of 24,000 to 25,000 tons (but with only' ten 12-ii. guns); and the Lion, also of the British navy, with a displacement of 26,000 tons, on all of which the main battery is ar- Fanged to fire on either side. : Hull. Will be of the following dimensions: Length, 585 ft.; breadth, 98 ft.; nor- mal draught, 27 ft. 6 in. | The heights above the normal wa- | ter line will be: as follows: Fore- ee, *Revise mal, a7 sa figures for displacement are: Nor- 00 tons; full load, 30,200 tons. castle. 25 it. 6 inj amidship, 22.40 8 int "astern, 17 tt. 1 in. These heights agree with those of English and American Dreadnoughts, as* at is 'generally conceded that a forecastle lower than 20 ft. would im- pair seaworthiness. Externally our ships will appear much like the British -- Lion, whose keel has just been laid at the dockyard at Devonport, or much like the Arkansas and Wyom- ing now building for the United States navy at the yard of the New York Ship Building Co., and Cramp's, re- spectively. The superstructure on the upper deck will be completely sup- pressed, to avoid obstruction to the are of fire of the main guns, as well as to reduce the target surface. -- Starboard waist gun: Fires across ship 60 degrees forward of beam and 40 degrees abaft. ; - Port waist gun: Fires across ship 60 degrees abaft of beam and 40 de- grees forward. Armor. For the protection of machinery and boilers there will be a main ar- mor belt, of 12-in. uniform thickness, 200 ft. long, and extending Af, 9 in. 349 above and 3 ft. 4 in. below the nor- mal water line. This belt will be continued 75 ft. more at each end, till it comes abreast of the extreme turrets, but its thick- ness is reduced to 10 in. These belts will taper down from their original thickness to a thickness of 5 in. at the lower edge in a height of about 2 ft. On top of the main belt, for its whole length of 400 ft. there will be armor 9 in. thick at its lower edge, tapering down to 8 in. at the upper deck. Beyond the central redoubt the armor belt will be 6 in. thick for- ward and 4 in. thick abaft and will ex- tend from the same depth below the water line up to gun deck. Besides the main belt and the side armor éx- tending between the centers of the extreme turrets, there will be also, at the level of said turrets, some trans- verse armor extending from side to side, thus completing the atmored box that will protect machinery, boil- er, magazines, the main and second- ary batteries. Above the upper deck there will be armor 6 in. thick for protection of the 6-in. guns. To avoid all dangers inherent to perfora- tion of the smoke-stacks, same will be protected by 114 in. nickel. steel ex- tending from their base up to 15 ft. above the upper deck. The arrange- ment of armor follows English, Amer- ican, and Japanese ideas; but, as re- gards thickness and distribution, it resembles what has been adopted on the Japanese ships now building. The total weight of all armor, barbettes, turrets, etc., amounts to about 7,000 tons. Underwater Protection. Six hundred tons nickel steel has been allotted for this purpose, and it will be used for an inner bottom and two longitudinal bulkheads, one on each side. This protection will be completed by the ordinary double bottom and the system of transverse and longitudinal bulkheads, dividing the ship into numerous water-tight 'compartments fitted with electrically driven centrifugal pumps which can be operated even when the compart- ment is entirely flooded. Externally a steel torpedo net is held 30 ft. from the ship's sides. Machinery and Coal Bunkers. The motive power is composed of steam turbines, located in three sep- arate and independent compartments. The main boilers are arranged in six compartments, three forward and three abaft of the engine rooms. In the case of serious accident to the
