ness of 6 in. 1903.] MARINE REVIEW AND MARINE RECORD. 31 ARMORED CRUISER COLORADO LAUNCHED. The armored cruiser Colorado was launched from Cramps ship yard, Philadelphia, last Saturday. 'This vessel is 502 ft. long, 59 ft. 6 in. wide and draws 24 ft. 6 in. Her speed require- ment calls for 22 knots an hour for four consecutive hours. She is fitted with twin triple-expansion engines capable of developing 23,000 H. P. All the armor is of the most improved Krupp type. The waterline region is guarded by a 7%4-ft. belt reaching from bow to stern. Amidships, for a distance of 244 ft. abreast the engines, boilers and magazines, the belt has a maximum thick- Forward and aft this belt will have a uniform thickness of 3% in. Five-inch armor will surround the 6-in guns at the four corners of the superstructure on the main deck. - The four 8-in. guns are mounted in two balanced turrets, with slanting faces, having armor 6 and 6% in. thick. <A belt of cel- lulose, extending from bow to stern above the protective deck, will automatically plug all shot holes admitting water. The fighting force of the Colorado is centered principally in two batteries. She will carry a main battery of four up-to-date 8-in. and fourteen 6-in. rapid-fire rifles, a secondary battery of eighteen 14-pounders and twelve 3-pounders, and a supplemental force of eight 1-pounders, two field-pieces, two machine guns and six automatic guns for service on the bridges and in the tops. The 8-in. guns are designed to fire once every fifty seconds and the 6-in. guns three times a minute. The contract price of the Colorado was $3,780,000. TRADE NOTES. Albert Frank & Co., general advertising agents, will remove on or about May 1 to the Board Exchange building, 25 Broad street, New York. Very interesting are the two pamphlets which the Chicago Pneumatic 'Tool Co. has just issued--one devoted to its tool factory in Cleveland and the other the tool factory at Detroit. The Cleveland pamphlet deals with drills and the Detroit pam- phlet with hammers. Concerning the care of hammers the com- pany says: "Pneumatic hammers, like all other classes of ma- chinery, must receive proper care and lubrication in order to give proper results, therefore, one of the most important factors connected with their care is to keep them clean and well lubri- cated. As the air taken into the compressor generally contains some particles of grit and dust, it is almost impossible to prevent this foreign matter from entering into the working parts of the hammer, catising the parts to become clogged and rendering the hammer inoperative. 'The use of a poor grade of heavy-bodied oil will also cause the same trouble. A good plan to follow in such cases is to clean by using benzine freely through the throttle handle. This dislodges all foreign matter and cuts the thick oil which can then be removed by blowing the air through the ham- mer." The pamphlet contains an excellent comparison as to cost of hand and hammer-driven rivets on structural work. 'The advantage is, of course, greatly in favor of the hammer. All "Little Giant" drills and reversible machines are made after a standard design or pattern, varying only in size and comstruction necessary to adapt them to the particular uses for which they are intended. These machines are of the balanced piston type and consist of four single-acting cylinders, arranged in pairs, each pair of pistons being connected to opposite wrists of a double crank shaft; each piston of each pair travels in opposite directions at all parts of the stroke, thereby insuring a smooth running machine. 'The balanced piston valves are set to cut off at five-eighths of the full stroke, thus insuring economy in the use of air without sacrificing speed or power. ITEMS OF GENERAL INTEREST. Misfortune has again attended the battleship Iowa. A steam pipe burst and tore away the steering gear. The ship is now at Pensacola where she will be repaired. Members of the original United States Steel Corporation syndicate, who put up $25,000,000 in cash and stood liable to have put up $175,000,000 more, received last week from J. P. Morgan & Co. notice of the dissolution of the syndicate and of their final share in the distribution of profits, aggregating about $50,000,000, or 200 per cent. 'Their original cash deposit of 12% per cent. was long ago returned. Chief kKingineer Towne of the Cramp ship yard called at the navy department last week and conferred with the officials re- garding the Maine's boilers. Mr. Towne, after a thorough exam- ination of the battleship at League island, insists that the bending and bursting of the tubes in the boilers was due to the incom- petency of the engineers and that if the boilers had been properly handled the accidents would not have occurred. The life-saving device known as the Carley float, and which has several times been referred to in these columns, is meeting with great favor among yachtsmen along the Atlantic seaboard. This device is so well suited to saving life under various con- ditions and is so easily handled--it is very light of weight and needs simply to be thrown overboard--that it will certainly come into general use on all kinds of vessels. Among yachts from which orders have recently been received are the Delaware, Aloha, Thesis, Aztec, Dreamer, Pantooset and several others. Last year was an exceptionally good one for the General Electric Co. The profits were $10,277,000. 'Total sales of elec- trical apparatus and supplies amounted to $36,665,598, while the orders received amounted to $30,044,454, being an increase of 16 per cent. upon orders received during the year ending Jan. 31, 1902. After making allowance for the purchase of patents, chiefly those of the Sprague Electric Co., and after a stock issue restor- ing the percentage of reduction made in 1893 of $16,746,133.33, and after paying dividends and interest on debentures there re- mained a surplus at the close of the fiscal year of $4,482,701.99. The capital stock of the company is $41,880,733.33. Irving M. Scott, for many years vice-president and general manager of the Union Iron Works, died at his home in San Francisco this week. He had not been in health for a long time but his death was unexpected. He was one of the most pro- gressive ship builders in the world. The Oregon is the most famous vessel which he built, owing to her spectacular tour around the horn during the incipient stages of the. Spanish- American war; but naval men have always looked upon the Olympia as the best product of the Union Iron Works. "The Olympia was regarded for her size as the best balanced ship in the navy. Mr. Scott was very active in public life and' was ee mentioned as a candidate for vice-president of the United tates. Le Vessel men of the great lakes have had during the week a striking example of the necessity of whipping a union, when. it deserves to be whipped. The settlement with the firemen's union has apparently given the firemen an erroneous impression of their power. 'hey have made trouble at one or two ports since the agreement with them was signed. At Cleveland. it ap- pears that they endeavored to enforce the moribund principle that seniority should be observed--that is they held that a fire- man who was an old member of the union should have priority over a new member. 'his, of course, virtually destroyed the first precept of unionism but the firemen could not see it. At Buffalo the union refused to allow a vessel to go out until another oiler had been employed, though the agreement specifically provides that nothing must delay the movement of vessels but that all differences which arise must be settled by arbitration. All these things are merely effects. The catise is the original surrender of the vessel men to an unjust demand.
