Marino signals- wero used among tho onrly Greeks and Persians, and wore, made by means of the sails. Gloaming Arcs wofo used for night signals. A VonUlnn Invent¬ ed a system of coloied lings about tho sumo time.

In 1804 Congress etmut- cd thnt all vessels currying siciiin siiould at night display a white light at the foremast head, a rod light on tho port side and a gr'cen light on the starboard sldo. Previous lit this there waB no rule regarding vessel's lights. The shade ol tho colored light is not yot rog- ulati'd. It Is also woll understood that the science of blending colors Is an Intricate one and to produce the best colorod light sci¬ ence must be brought Into requisition. Tho enterprising firm of Fcltlioimcn & Russell, of Buffalo, have given special attention to tills matter and have, aB a veeult, produced asotof perfect signal lamps. Tho-lumps are thiee In number, with red, green and white lights, and aro handsomely finished. The timing In the gln»B nine M>rili'iilly, as will bo sf.en.bv tho lollowlngciit. Each flute shows a sepinato light when close by, but ata distance they blend In cue and show a ball of light. It .may seem s 11 a n g o to those who have not stud¬ ied the science of colors that a giecn light is pro¬ duced by the rellow light shining through the deep blue glass or lens, but such Is the fact. All the discovei les of -m o tl-» r n science bearing on the subject having been tak¬ en into consideration, is It unv wonder that the New Fluted Lens Signal Lamps nave secured a world-wide reputationV Wo,are'informed by Upson, Walton & Co,, who have them on sale In Cleveland, and by others, that the di mand for them lias been very great, and all who use thorn sponK In their praise. They are'mado of the bc-Bt material and finished in the most substantial maimer possible. Probably no higher compliment could be given to Messrs. FelthouBen & Russell's lamps than tho fact that the lailips have been ordered for the wonderful yacht of Joy Gould, the Atulantii. This order was se->' cured through their agents, Messrs. Dar- rnh « El«ell, or Philadelphia.* EaBtem tioilses of older standing ottered to furnish lumps at lowor figures, but the millionaire must have the best, so the order enmo to Buffalo. Foltliouseu & RubsoII have agen¬ cies in the principal marine cities. If In getting you would get tho besCfor sail ves¬ sel, yacht, or steamer, secure? the New fluted Lens Signal Lamp. They can be seen more distinctly and further, It Is claimed, than any other lamp. In certain localities, some pecullai lights 'have been seen 40 or 50 miles. From High Point on the Cntskllls. r ickots were distinctly seen 100 miles away when «hot off at the Biooklyn bridge open¬ ing. Through the dry atmosphere of Color¬ ado mounAilns can bo seen 150 miles distant. Now tho clear, distinct light'of those lamps penetrates the fog and darkness farther than o dliiaiy lamps, and so their value. Is en¬ hanced. Mariners nt moot have dangers euu b mciclal, of Bnllalo, and tho Express, ot tho s line i Ity, as also the Nauticaf Gazette, ol New York, have recently had articles, on tills subject and speak in most fluttering tonus of these lamps and of the superiority of the woik done by this firm.

The Issue Is a slmplu one. Shall we build unsafe yachts whoso speed rests mainly In sparring without regai d to a vessel's capacity to carry the rlg,nr shall we turn the lessons of reqent years to account nnd demand fiom modelers something worthier of out admira¬ tion In the way of vessel's speedy, safe and with grand aeeonimodatlonal' The answer from the public Ik not diftlculc to divine, Helped along by the serious disasters In tho past and by tho line sailing displayed bv yachts of safe depth and displacement, It is -not difficult to piophcsy the outcome of tho future.
