MAGNETIC SURVEY.

CARNEGIE TO REVISIT LYTTELTON. From among the infinite variety of «hips of all classes throughout tho world, one small sailing vessel—tho Carnegie—stands out as being the only seagoing craft -which has neither steel nor iron in her hull or fitting. Thero is a purposo behind lior uniquo style of construction. She was built by the Carnegie Instituto of America specially for tracing through tho ocean spaccs of tho world tho devious curves which tho magnetic polo lays out for tho compass needle to follow. _ > Carrying sufficient provisions to lasE two years, and fitted out for a vovajw of 6500 miles, tho Carnegie left Washington (U.S.A.) in October to follow tho declination of the compass through tho South Atlantic nnd Pacific Ocenns. Tho port of call planned for tho Carnegie is Dakar, on the West African coast, and thereafter her course "will tako her to Buenos Ayrcs, St. Helena, Aden, and Perth. After that her course has not definitely been determined, but it is probable that tho vessel tvifl visit Melbourne, proceeding thence to New Zealand, Polynesia, Honolulu, and Panama. Tho Carnegie is a smart-looking brigantin* of about 300 tons, and as tho delirnto naturo of her observations necessitates a complete absence of steol ond iron about h*r to interfere with her work, only -wood, copper, and bronzo woro used in her construction. Her master, Captain J. P. Ault, commands j:. cTew of 17 men, who will sail her on the present world voyage. .She also carries expert mngnetidans. scientists, and observers. Though tlio ehi*f work of the scientific investigators will bo in studying the declination of the compass, the Carnegie is equipped with a variety of instruments to be used in gathering data on other problems. Her route, will intersect paths previously followed by other observing parties, and allow a check to bo made between new nnd old findings on compass deviation. This is the fifth, and will probably bo the last, trin of tho Carnegie in this capacity, which has already taken hor through 200,000 miles of ocean waste during the last 10 years, and has resulted in much information being incorporated in the magnetic charts of mariners. On her previous cruise tho Carnegie arrived at Lvttelton from New York on November :?rd, 1915. She sailed on December 6th on a cruiso round tho world in southern latitudes, returning to Lyttelton on April Ist, 1916, and subsequently returning to Washington.
