24 der to reduce friction. This stem forms a casing for the electric wires which enter the side of the mount through an opening. Surrounding the stationary cylinder is a revolving lens attachment in the form of a cylindrical sleeve, having an opening in one part of it fitted with a suitable lens hinged thereto'on both sides, which not only increases the range over which the light is visible but provides for a screen which pro- tects the operator from the glare of same and concentrates the rays di- rectly on to the object of intercourse. The sleeve mentioned may rest upon a flange around the base of the cylin- der and may be rotated by hand to direct. the rays toward the 'desired quarter. Where this part of the ap- paratus can not be worked directly by hand, it may be driven round by a pinion acting on a toothed ring and actuated by a shaft in any suitable manner. The drawings, with the ex- ception of Figs. 3°and.5, show a sim- ple arrangement in which teeth are inserted into the lower part of the sleeve, forming as it were a toothed ring surrounding the lens attachment, adapted to be actuated by an ordi- nary chain such as shown in Fig. 1 passing over a pair of guide pulleys © and extending vertically to any de- sired level, where an actuated wheel suitable for turning by hand is mount- ed in any convenient manner. Ventilation holes are provided in the base of the fixed cylinder, and the inner or rotatable one also has spaces to promote circulation and cooling of the lantern. A cover provided with ventilating means is fitted upon the stationary cylinder and its flange may serve to retain the sleeve in position. After each impulse of the inner cylin- der by the lever in one direction it is returned to its original position by a spring, shown in Fig. 3. The revolv- ing lens attachment can, if desired, be made so as to provide an opening of variable size. The post or stand- ard on which the whole of the -light- ing apparatus is mounted may _ be adapted for adjustment to any desir- able height. Assistant Secretary of the Navy Newberry has approved the plans for the dredging of a channel at Pear] Harbor, Hawaiian Islands, and for the location of a dry dock to be con- structed there. Bids will be called for to be opened Dec. 1. The chan- nel is to be dredged to a depth of 35 ft. and a width of 200 yds. The appropriation for this work amounts to $400,000. THe Marine REVIEW ANCHOR FOR SUBMARINE OR SUBMERSIBLE BOATS. 'An improvement relating to the an- chor of a submarine or submersible boat has recently been patented in the United States by a French engi- neer. The invention relates to a new arrangement of the anchor, anchor plate or grappling anchor, and con- sists essentially in providing within the boat a vertical tube of suitable form and dimensions through which the anchor chain passes, and in which the anchor is accommodated in its raised position. In the accompanying drawing the anchor, the arms or flukes of which are not very long, is suspended ver- tically in a water-tight tube extend- ing through the hull of the vessel and terminating below in a cavity in the hull of a shape corresponding with that of a casing which would contain The suspending chain ex- tends through the tube and over the chain wheel, the slack being accom- modated in a tank on the outer sur- the anchor. face of the hull. The weighing or casting of the anchor does not neces- sitate the opening of the hull, and in no way modifies the stability and conditions of weight of the vessel. To weigh anchor the wheel is turned from within the vessel, and, when home, the anchor is stopped by the shoulder before its flukes touch the hull, being retained in this posi- tion by any suitable device, in this case by a pin passing through the links of the chain. In addition to the advantages named, the anchor thus accommodated offers no resistance to the travel of the vessel. The inventor is Maxime Laubeuf, of Paris. When the lighter Ariel, loaded with paraffine, took fire in the North river at New York recently, the Cunard liner Slavonia and the mail boat Post- master General were menaced by the flames. The: lighter was got safely to. midstream where the fire was ex- tinguished. She was then towed out and sunk on the Jersey flats. The loss is $25,000. NOTES AND CLIPPINGS. According to Lloyds Register wrecks reduced the effective mercan tile marine of the world in 1907 py 868 vessels, of 851,221 aggregate ton- nage, exclusive of vessels cf less than 100 tons. Great Britain's percentage of loss was less than that of any other of the principal ship owning countries. i ge 2 The Compagnie Generale Trans-At- lantique has established a new month- ly regular steamship service from Havre to Cuba and New Orleans, with an itinerary varying -- according to season. The Argentine parliament has de- cided to spend $55,000,000 on the construction of warships and the re- arming of the field artillery. European shipping companies are suffering severely because trade and trafic in the Levant and on the far eastern' lines are almost at a stand. Still. . The White Star Line will name its 'two new great vessels now building for the Atlantic service Olympic and Titanic. The keel blocks were re- cently laid down at Belfast of the Olympic. ; Scotland's fish catch in 1907 was 9,078,059 hundredweight, worth $15,- 425,525. The industry employed 94,- 773 men on 10,365 vessels of 141,385 aggregate tonnage, worth $23,640,561. Asbestos is found in the island, of Cyprus, in the -Mediterranean. A company organized in 1906 obtained a concession to open early in 1907. It is reported that 1,000 tons of asbes- tos were mined up to the end of the year. A Berlin engineering company is fitting out a large steamship with a suction gas plant for propulsion pur- poses. So confident are the owners in the succcss of the innovation that they have ordered two more ships to be similarly equipped. At. Dumbarton, Scotland, a ship building firm would like to get a por- tion of the parish church burying ground in order to extend their prem- ises, and while some people do not mind, others think it would be a sacrilege to agree. The firm, if it doesn't get the bit of ground, will, it is feared, have to leave Levenside for some other place on the Clyde where more accommodation is avail- able. Some experiments have been recent- ly carried out which appear to show that the sea water round the coast of Ireland possesses a richness in radium not hitherto expected. This result has been extended by measure-
