T It is stated that Captain Peter Lrnng will take- charge of the topsail schooner Waratah in place of Captain A. Running.

The Cunard liner Caronia in June arrivea at Liverpool with 2174 passengers, the largest number that has ever been carried from America on a single ship. An interesting alteration in present rubthods of combating fires at &ea has been adopted for the now Cunarders. Mauritania Hid Lusitania. Pipes are carried from the top of each hold to an airtight box with a. glass front placed in tho chartioom or ether suitable place. At the top of the box v an electric fan. to which tho current is automatically switched on at regular interTale by a clock. Aβ the fan revolves it sacks air from the holds through the pipes, find the presence of smoke in any hold is at once appa.ect to the officer in charge of the Apparatus. Should smoke be seen to lune trom a pipe the mouth of the pip* in at once connected by a flexible metallic tub with the vessel's boilers, and steam ie forced into tho hold from which smoke comes. The question raised as to the visibility of the Lizard light in connection with tho wreck of the Suevie has drawn attention to problems connected with th* relative efficioncy and visibility of the various ilhuninants • used in lighthouse work (writes "Tne Times Engineering"). ■Scxaio yews ago the subject was investigated by a royal commission, but conditions have changed in Ui« interval. On tie main question of visibility, it is obvious that the case is mainly governed by atmospherio condition*; but it is stated that in foggy weather th* incandescent oil light ihaa a penetrative effect superior to that of the electric arc. There is further to be taken into account the elevation of the light above the level of the sea, which, of course, is subject to a wellknown law. The condition of the atmosphere ia, however, a vital factor. It is well known, too, that the conditions of ihe atmosphere, in addition to its influence on rang*, have an effect upon colour. Oil, ga«, and electricity are ail in uee as lighthouse Uluminants, but the employment of the laet, for reason* tm'.-.t msr to cori of installation and expense of upkeep, is confined to "salient headland*. The great development during reoont years has been in the application, of the incandescent burner to lighthouse work, the system which is now finding most favour with ttie authorities being tie incandescent petroleum vapour burner. The object of the authorities a/t present Iβ to obtain the flashes *t very short intervale, and to reduce the duration of the long dark period in groupflariiing lights. A typical example of th* modern lighthouse cystem is found in tho Beachy Heed light. In some recent lighthoure installations, notably the Faetnet β-nd the Maiden, the aparafois is installed in biform, to that in foggy weatheT two synchronised light* ace used. These lighte sx* placed perpendioularly, but in French practice the two lights are placed eide by side on tlie same revolving plaifoTm. and, although the object in the case of Britfeh lighthouse* is to irrreafo tVe inuminoiffnjr power in foggy weather, ft h»s been noted in the case <A the electrio light tbrat a grea>ter oandle-poweT ie obtained wifn two arc lamp* than with a single one twing the same amperage and voltage. Triform and qußdriferm apparatus is aleo eattnloyed p*rtiou'arly w-'th gas inrtsllaitione. which until a reivnt period were kre-ely in iim on the Tri»Ti coast. These, however, are being gradually unp-nlfinted "by the ineandw>ent oil <bi>.rn*r, whirh. from appears to be the amwetus of the future in connection with lighthouse work.
