Our illustration of the Ward Line steamer Newport, of the Havana Line, is again pre- seuted through the courtesy of the Nautical Gazette. ‘The illustration has proved to be a popular one, and the former edition of the ReEcorD containing the same. is completely exhausted, STEAMBOAT ACCIDENTS. To avoid accidents the ocean steamers leave New York by one route and return by another, avoiding iiability to collision in ateg. would be willing to pat up with discomforts if they were characteristic of fast ships. ‘These vessels are unquestionably safe, but it Is urged that in future years owners of fast lines will especially aim to have ships built that are not liable to break doen and that are as unsinkable as possible. ‘There are many advocates of twin-screw steamers, ves- sels having two screws and built: with longi- tudinal and transverse bulkheads. In this way it is thought that the liability to break down is decreased, as there ave two en- zines and two screws in the place of one. It is urged that with a ship of this class there is not the same chance of breaking stern- posts and rudders so often as in transatlantic upon the subject. Within a few miles of this city, 20 coal mining machines are digging 40 tons of coal per 24 hours each, at a cost invasion, in spite of all that hag been said of less than $20. ‘To mine this by hand would cost $32, and yet it does not appear that the operator in question employs fewer men, for to remove the products of these machines requires an inereasing force. Within a short distance of this city, in another direction, steel rails are made from the loglike bloom, without the intervention of human skill ex- cept to control the movements of the re- rkable machinery. ‘That the employment of such mechanism is a curse to be deplored by workmen, is an argument met by the plied by two single ended, and two double ended boilers. In place of the old-fashioned dead-eye, side-light, square openings of liberal size are eut in the sides, provided with iron shutters on the outside and glazed sash on the inside, This will add vastly to the comfort.of pas- sengers. The incandescent electric light will be fitted all over the ship. Steam steering gear of approved make will be located in the pilot house, with hand power attachment in reserve. Serew gear will be placed att for additional security. A steam windlass, with evpstan, will be ar- ranged forward and two steam capstans aft. A steam deck pump will be provided both On the outward passage the steamer crosses the meridian of 50 at 42 degrees Jatitude, or nothing to the north of 42 degrees. On the homeward passage the other steamer crosses the meridian of 50 at 43 drgrees or nothing to the south of 43 degrees. This gives a degree of latitude or GO"niles in which steamers are clear of each other, and so avoid collisions. Another class of accidents is provided for by building strong ships. An old sea cap- tain treats them on this wise: “A trotting horse driven at the top of his speed tora mile or s0 rather enjoys the sport, but if he is pushed until he is fagged he is apt to be injured. And so it will rack a ship to drive her at the top of her speed in the faceofa hurricane. A ship on entering a heavy sea should be allowed to get along quietly, and opportunities should be watched for to take jadvantage of them. Vessels of small power cannot well keep in position in atorm, while full power steamers can hold themselves head on against the sea, ‘Trav- elers will favor the fastest ship in most in- stances, and are peculiarly happy if they can make a voyage in an hour or two less than their friends. ‘To enjoy a swift passage many WARD LINE STEAMER NEWPORT. steamers. terially strengthens the ship.’’ — <— [5S THERE A LIMIT TO MECHANICAL INGENUITY? Says the Pittsburg Telegraph: ‘The substi- tution of mechanical for human labor is in- creasing at arate that arouses the mental question, is there any limit to the capacity of mechanical ingenuity and accomplish- ment? The area of territory as yet uncon- quered by the inventor grows narrower daily, and it may be said, in relation to Pitts- burgh’s industries that there is but one pro- cess which exists to-day as it did at its in- ception, ‘This is found in the peculiar labor of the glass’ blower. In other local industries the mechanical puddler, the coal digging machine, the brick making machine, the roll, the steam riveter and flanger, the steam hammer and the automatic mechanism of the rail mill, have all invaded the territory of human muscle to a degree undreamed of a generation ago. And the wages of the workmen have not suffered through this The longitudinal bulkhead ma- {assurance that it is only by the use of such devices that the great mill cen be kept going in these troubulous times of tariff talk and low pri The ma of machinery is, altogether, a victorious as well as an in- teresting one, and to none more interesting thansthe Pittsburgher. $$ A NEW STEAMSHIP. The Mariposa is a new steamer building by Cramp & Son, of Philadelphia; ‘she is of the tollowing dimensions: length, 350 feet; breadth, 41 feet; depth of hold, 26 feet; gross tonnage, about 3,000 tons. “The propelling machinery will be of the compound, three cylinder type, of about 3,000 horse power; with the high pressure eylinder 43 inch diameter, the low pressure 6Linch diameter, and all 51 inch stroke of piston. An independent centrifugal pump will be used for circulating water through the condenser, and for freeing the ship in case of a large leak. The engines will be reversed by the steam gear. ‘The propeller will be built up and made of charcoal iron. Steam of 80 pounds pressure will be sup- yorward and aft. There will be steam ele- vators in each of the main. hatehes for load- ing and unloading cargo.— Mechanical News. A THREAT TO LAKE TRAFFIC. It is reported since the failure to make the northwest: traffic agreement, that the rail roads have agreed to bring Dakota and Min- nesota traffic all rail by way of Chicago, leaving no business tor the boats, and per- haps resulting in the withdrawing of the boat lines. The object is to punish the li- nois Central, but this action may result in more railroad building into both Minnesota and Dakota. ———_ The Piction G te says: ©We are an- thorized to state that the government have finally decided to erect one life station at Wellington, in charge of Captain Hugin Me Cullough; and another at Popular Point, in charge of Captain Leroy Spaflord, At) Sal- mon Point, the cannon, which is to be tired atintervals in snow storms or foggy weather, is to be placed in charge of Captain L.
