continuous. service. Metallic packing will be fitted to all piston and valve rods. The condenser will be of sur- face type, of cast iron, and, as the circulating water may be as high as 85 F. and will hold a considerable amount of mud in suspension, the water supply will require to be more abundant and the tubes of larger di- ameter than usual. The usual air and centrifugal circulating pumps will be installed. The dredging pump will be centrif- ugal, 32-in. diameter .of discharge, of double-suction, shrouded runner. type, lined throughout with removable lin- ers, the pump-cas-ng to be of cast iron in five parts. The discharge of the dredg ng pump will be overhead to the guard of the dredge, and will. be di- rected at will to either side by a hori- zontal elbow. A priming valve and continuing pipe line to the guard will be on either side of the dredge, and will be fixed in position, the entire ponton pipe-line being joined to either as desired. The pump engines and dredging pumps will be supplied by the: E, H. Abadie Co,; St. Louis, Mo; at a total cost of $34,595. The Schoell- horn-Albrecht Machine Co., St. Louis, Mo., will supply four hauling winches at a cost of $6,400. The contract price for the hulls with the pontons and pipe lines was $238,000. The suction-head to the main dredg- ing pump will consist of two members each 13 ft. 834 in. long, connected by the junction boxes for two. 10-in. jet-header or pressure pipes, which will extend from the boxes each way completely across the suction-head. The suction-head will be 29 ft. 914 ins. wide over all and will be arranged for dredging, going ahead or astern. Two steady-bars will support the suction- head in operation, and will work in cast-steel guides on the bow girder of the dredge. There will be five cast-iron sheaves with suitable frames for the hoisting tackle, the fall, of 34 in. wire rope, to be suitably connected to an auxiliary drum on the main hauling winch. The discharge from the dredge will be directed to the ponton line by a sliding or telescoping pipe, which will consist of sixteen 15- ft. sections, and will be 32 in. in di- ameter. Flexible joints will be fitted throughout. A derrick will be located near the forward end of the after ponton, and will be so constructed as to handle easily any movable part of the. pipe-line connecting the dredge and ponton. There will be four steam capstans, two for'ard and two aft, each to be double-geared and reversing, with two TAE MaARINE REVIEW steam cylinders 7-in. diameter by 8-in. stroke. "TFwo hauling winches will be placed, one on either side of the 'boat at the forward end of the deck-house, and will have drums ar- ranged to handle the spud-anchor and suction-head. The steam steering gear will have double cylinders 414-in. di- ameter by 7-in., to be fitted with raw- hide gear for noiseless operation. A machine-shop will be located in the forward end of the after engine room. The forward cabin will be 75 ft. long by 32 ft. wide and will contain a central hall with state, bath, and wash- rooms adjoining. The hall will be di- vided into office and officers' mess room. The after cabin will be 60 it. long by 35 ft. wide, its forward end being deyoted to kitchen, store-room, etc. There will be the usual cabins, toilets, and accommodation for crew. main the NOTES AND COMMENTS. At the present day the United States Lighthouse Establishment has in use 1,495 lighthouses and beacon lights, 60 lightships,. 142 gas-lighted buoys, 450 fog signals, 1,813 postlights, 683 unlighted day beacons, 95 whis- tling buoys, 137 bell buoys, and 5,212 buoys. of all other kinds. A crab was captured recently at Montrose, Scotland, which was marked and liberated off Scarborough, Eng., 23\years ago. The © distance 'in a straight line is over 200 miles, but it is probable that the crustacean tacked considerably on its course. : Ergin is a liquid fuel from Ger- many. It is obtained from tar by a secret process and is reported to have a heating power of 16,500 Brit- ish Thermal Units per pound. Point Reyes Lighthouse, in South- ern California, is built upon a higher natural location than any light in the world. The Diamond Shoals Light- ship, off Cape Hatteras, where storms and sand banks make the "graveyard of the Atlantic," is: said to be 'the strongest lightship in the world. The French have invented a_tor- pedo which works its' way to the ob- ject fired at by a series of curves. On an oceasion recently, after a tor- pedo had been -fired- off, it did the curve business so. successfully that the vessel whence it was fired had the greatest difficulty in getting out of the way to reach a place of safety. The steam whistle was first used in 1833, and was invented by George Stephenson at the request of the man- ager of the railway line Stephenson. had built. Hitherto the engineer on oe: the locomotive blew a horn, but the result wasn't always: satisfactory, A dock cut from. solid rock has been put in operation on Lake Vic- toria Nyanza, at an altitude of 3,800 ft. : Enlisted men in the navy are to re-. ceive $1 extra for each day they serve on a submarine that is submerged. That will please them if they can come to the surface and collect it-- Chicago News. Arbroath is mourning the loss of the Dart, one of the most ancient ships on. the east coast of Scotland. She was built at Chepstow in 1826 and wrecked at Holy Island recently, the crew getting ashore all safe. The British Royal navy has recent- ly developed a flag for the exclusive use of submarine vessels, which bears on one portion a representation of two white mice. .These tiny creatures are carried on board the submarine, be- cause they are very sensitive to the presence of noxious gases, and their usefulness in this respect has got them the honor of a place on the submarine bunting. It is reported that experiments will shortly be conducted at Toulon w:th a new turbine torpedo of greater speed than any at present: in exist- ence, capable of traveling a distance of over 2,000 meters and of carrying a much larger charge of explosive than any torpedo now in use. 3 The Sailor's Friend, a lifeboat. built at a cost of $15,000, subscribed for by the residents and visitors, has: been launched at Frinton-on-Sea, England. A bottle of water was used in place of the usual wine, all of the lifeboat crew being total abstainers. In Norway dried seaweed is freely used as fuel. ga There are more sharks in the Med- iterranean this year than usual. It is. supposed that submarine explosions during the late war, between Japan and Russia have driven these fish to seek more peaceful homes. In the Fiotds - of "Norway --.the clearness of the water is wonderful. Objects the size of a small coin may -- be seen at a 'depth of 20 to 30 fath- oms. Mark Twain is credited with saying, after his tour of inspection through the Lusitania, "Well, I guess I'll have to tell Noah all about this when I meet him," : A Danish engineer, H.C: Vogt, of Copenhagen, has invented a propeller for, ships that attempts to imitate the action of a fish's tail and combines driving with steering power.
