HBv Wnsblnglou. Thoro lias been pre-HO pre-HO sentod to (ho bureau of navigation of Vffl''; the United Slates navy an Ingenious Bfl. device to aid In taking observations Hvm to determine a ship's position, and Kffl which, It adopted, will not yield, and Kjj5 is not expected to yield a dollar of immm profit to tho Inventor, Capt. H. A. God. sen, a retired Mariner, now enjoying tho comforts of lite aahoro at No. C Blnden road, London. Capt. Qadsen's invention Is as Important Im-portant relatively as tho sextant Itself. The Japanese navy used It In the war with Russia, and to Its employment tho commanders of eight ships ascribed as-cribed In a largo moasuro their ability to .surprise tho enemy. Divested of its technical nomenclature, nomencla-ture, tho Invention, which Is called tho "spanner horizon," Is intended to correct cor-rect a falsa horizon, which tho navigator navi-gator dreads almost as much as ho sloes the unchnrted sunken rock, tor he may bo carried many miles out of his course, and not Infrequently to a dangerous ambush. In tho patbloss lane ho Is following, Ever slnco tho tlmo when tho hardy Norsemen ventured out of sight of (and, guided only by a rudo compass, depondenco has been placed upon tho Ha horizon tor thoso observations of the celestial' bodies which enabled tho navigator to fix his position upon and shape his course acr.pss tho vast expanse ex-panse of tho occanS.

This Is the case even chen the sun or stars are shining rightly and only tho horizon Is ob-The ob-The great danger, and which has ared many a good ship to her destruo-Ion, destruo-Ion, is the counterfeit horizon, which ippears so clear and well defined that t will docelve experienced navigators -wen who have been deceived heforo ly the same falBO assurance that they were looking upon the real horizon, ifcure in the belief that Mb "sights re good," which ia tho nautical way t: saying that the safety signals nro M, the mariner stands boldly on his course only to find that ho Is sovcral miles out of hlo reckoning, and has made a had landfall. Tho falso horl-ion horl-ion 'at sea la as cruol a. deception by Dame Nature as the mlrago on land which presents to tho thirsty traveler k .limpid stream almost within reach The spanner horizon is so called bo-Muse. bo-Muse. It exactly spans the porlphory tfkthe sun's imago reflected on the korison glass of a sortant whon day Bseerratloas are taken. It carries a irtntralwlre for night work, on which a star, a light ashore or afloat or other Binalt object may bo brought in lino. On the darkest nights the altitudes of the stars may he (taken with thq cpanner. In the daytime, when tho horizon is obscured and tho limbs of the sun are brought between tho logs of tho Instrument, tho altltudo of the sun's center Is obtained and the truo horizon Is established. Capt. Qadsen invented the Instru-nA"-fter his retirement from nn active ac-tive seafaring life. Its value no an aid to navigation was racognlzed by English mariners and It was suggested suggest-ed that a company bo formed for the manufacture of the auxiliary to tho sextant, but Capt. Gadson, who Is middle-aged and "sot" in his ideas, would Mt consider tho proposition. Tho sat-Isfactlon sat-Isfactlon that ho win derive, and all he uks for, is the approval of the navigators nav-igators who And his invention to bo M practical ana noipmi, no would rather PHIW)f that a hundred ships had laid a H&attlb course and avoided danger with KjHI ro aid, ot his. spanner horizon than to LvWs rw5el,vV hundred thousand gulnoos. |
