In this paper, the author intends to describe how the "Kotaka" (a little river gun boat) was lifted by a crane and put on board a ship when she was transported from the Tama Dock Yard, Japan, to Shanghai. The hull of the boat is not so strong since she has very light scantlings, but she displaces 60 tons at the normal condition and her weight lifted was such amount as 53.5 tons. Therefore, it is a rare case to do such a work, and there were troubles to be overcome. You will be interested in the author's explanation about the following items : -The outline of the subject. The general feature of the "Kotaka" The calculation for the lifting arrangement. The result of the work. etc.

The Navy Experimental Tank was destroyed by the earthquake, 1923. The building of new large tank is now going on, but a few years more will be required for completion. So that as a means of the exigency, following an example of Viscount Tokugawa's small tank (25'×3'×2')in his residence for his own experimental work, a small tank (100'×6'×4') has been constructed, provided with the carriage, dynamometer &c. all in the principle of Froude's Tank. In spite of the small value of VL, the measured resistances of 4 feet and 5 feet ship models were found very steady and accurate. In comparing with the results of the Mitsubishi Tank and those of the late navy tank for the same models or similar models applying the Froude's law of friction, the new small tank gave pleasingly good results. The author from his own experience on the design of ships emphasizes an advantage of providing such a tank in a shipyard for the personal guidance of its naval architects, although he, by no means, entertains an idea that small tank shall have the same reliability and accuracy of a large one. It is interesting however that there are certain unique advantages on the side of a small tank, and the experiments to utilize these advantages have been planned and some of them already undertaken, such as the investigations of ships resistance on (a) the effect of the temperature or viscosity to throw some light on the law of friction by simply beating or cooling water in the tank, (b) the effect of the density by easily changing the quality of water, (c) the effect of the depth and width of water by means of simply lowering or raising the dynamometer and a part of the carriage and providing false sides to the tank, all these will be immensely expensive to do for large tanks if not impossible.

It is said that electrification of the auxiliaries on small cargo ship is more useful than that of steam drive. The O.S.K steamer"Ondo Maru"(680 gross tons) had installed a main diesel engine of 600 B.H.P., steam driven auxiliary engines and an oil burning boiler. The fuel consumption was too much and so the next ship of same type"Mihara Maru"had installed the electric driven auxiliaries of d.c. system, and got good result. These valuable experiences tell us that the electrification is more useful than steam drive. The electrification of the auxiliaries had almost adapted the d.c. system, by the reason that the characteristics for winch and windlass are more suitable than a.c. system. Therefore, the a.c. system for auxiliaries of cargo ship has been disregarded. However, it is considered that the a.c. system for the auxiliaries of small cargo ship is worth studing. Now, our company decided to build two small cargo ships of"F"type (about 510 gross tons) and I am planning the electrification of the a.c. 230 volts, 60 cycles, 3 phase, for the auxiliaries. Here we call, temporarily, the ship less than 500 gross tons, as the"small cargo ship". The ship of"F"type is installed a main Diesel engine of 550 B.H.P. and following auxiliares, The generater for the source of these auxiliaries are two sets of 55 k.v.a. which are drived by a Diesel engine respectively. (a) Winches 4 sets of 15 k.w. (b) Windlass 1 sets of 15 k.w. (c) Capstan 1 sets of 2 k.w. (d) Pumps 6 sets of 0.75 to 5 k.w. There are other electric installations as follows : (a) Room heaters. (b) Ordinary illuminating lamps and navigating lamps etc. (c) Wireless telegraphy. (d) Radio direction finder. (e) Echo sounding equipment. The electrification of winch, windlass and capstan by the induction motors of pole change wound rotor type, shall have many points of consideration. In this paper, it is concluded that the electrification of the auxiliaries on small cargo ship by a.c. system is rather suitable for quick building of ship, and cheapness of equipments and easy maintenance of auxiliaries.

This engine is of two-cycle airless-injection type and has been developed by Mitsubishi Zosen Kaisha after about five years of experiments and studies. The first four sets of the engine were adopted by Osaka Shosen Kaisha for their M. Ss. "NANKAI MARU" and "HOKKAI MARU" and the actual service records have now been obtained. This paper deals with some special features of the engine, such as the scavenging, combustion, mechanical efficiency and construction.

The "Argentina Maru" is the first motor passenger and cargo ship to be constructed under the special Shipbuilding Subsi〓y of the first grade gr〓nted by the Japanese Government, and this magnificent Round-the-Wor1d Liuer is wholly of Japanese construction aud materia1s. In vi〓w of these circumstances, it seems to be appropriate to make some reference to the ship ; therefore a general description of the vast design, construction, equipment, etc., is given in this paper.

It is a well known fact that oil tankers in loaded conditions sustain severe sagging stress on top-side member in rough weather. Time motor tanker "San Diego Maru" encountered extremely rough seas in Pacific Ocean during a winter voyage, resulting severe bucklings and some cracks on the upper deck plating and also upper strakes of longitudinal bulkheads in midship portion. The author analyses the causes of the damage referred to, describing her general longitudinal strength among waves, the effect of impinging water on decks, together with some investigation on the theoretical buckling stress on deck plating stiffened with beams of comparatively light scantling.

"Sumiyosi Maru" is the first Diesel-electric tug built in Japan, of which the speed control is of Ward-Leonard system. That was designed and equipped at Kawasaki Dock Yard Co., Ltd. for their own use. That was, also, equipped with as power plant to supply electric power for electric welding and compressed air to ships in harbour. The descriptions of hull, propelling machineries, power plant, trial trips and towing tests are successively set forth.

Here it is described two problems on the launching. The first relates to the geometry of the launching arrangement, and a method of calculation of the ship's draught during launching, etc. The second introduces an apparatus recording the compression of the crushing soft wood of the fore poppet during launching, with an actual record as example.

In the Yamamoto's feed-pump engine, the main valve chest and the auxiliary valve chest are made independent, so as to reduce the length of the main valve and the difference of expansion, and the space for the movement of the main valve was able to be uniformly distributed. The test results of 72 sets of feed-pumps with this system for high-pressure boilers of 200〜600 lbs./sq. in. are as follows : -1.The piston speed was uniform and the engine performance was smooth. 2.The shock, vibration and sound were reduced. 3.The efficiency of pumps was improved and the steam consumption was reduced. 4.It enabled to make starting and stopping of the engine easier and simplified the overhaul inspection. In this paper, the author precisely describes the improved points of this pump in comparison with the Weir's type, yet he says that these are not of absolute nature.
