til then little had been done except shore
observations on some Of the islands
along the coast since the notable voyages
Of the Challenger and the Gazelle. more
than 20 years ago
Observations were made from the con-
,erted wooden yacht Gallee which be-
tween August I. 1905, and May 81, 1908.

This was only the beginning Of the
work. The institute has already made
observations in many parts OF the. world

land It is estimated that a magnetic sur
vel of the world can be completed In
about 10 years more.
For the purpose Of making systematic
ditons on all the deep water seas Of the
world, the Carnegie institution 10 having
constructed magnetic survey vessel,
which has been specially designed for
this work by Henry j. Gielow. the de-
sgner Of some of our most successful
racing yachts. to whom We are indebted
for the following details OF her design
and construction: The ship Is entirely
original, being the nrst OF her kind to be
constructed. In order to render her prac-
tically nonmagnetic. no magnetic metals,
such as iron and steel have been al
lowed to enter into her construction. The
only magnetic material used Is tho thin
cast-iron liners OF the cylinders OF the
internal combustion engine with which
she Is fitted. Outside OF the liners and
| the steel cams for the valves this en-
| CINE Is constructed entirely of bronze.
AS she IL built for ocean surveys, the
vesse. 10 constructed in particularly
substan tial manner and combines, with
the strength Of merchant vessel all the
| beauty OF finish and workmanship Of a
yacht. Her dimensions arc: Length over
| all. 1856 feet 6 inches; length on load wa
! terline. 12s feet 4 inches; molden beam
SO feet; depth OF hold. II feet inches
displacement with all stores and equip
ment on board. 56s tons. She will have
full sail power, with a brigantne ria
carrying about 1880 square feet OF
plain sail. The lines Of the hull are fai,
and easy and indicate both power ant
sea-going qualities throughout The keel
stem. stern post. frames and deadwoot
will be Of white oak. tho deck beams
planliing and ceiling of yellow pine, ant
the deck of Oregon pine. The fastening.
will consist OF locust treenails, copper
and Tobin bronze bolts, and composition
spikes. All through bolts will be rivetec
over rings both inside and outside. Al
metal deck fittings. metal work on SPAR
and rigging will be of bronze copper ant
gun metal. The sx-cylinder. Internal
combustion engine Is for the purpose o
maneuvring the vessel when in port o
crowded roadsteads. or during calm
at sea. II Is capable OF developing u
indicated horsepower at $50 revolution
a minute, which driving feathcrln,
propeller Of special design. will give III
vessel a speed OF six knots in calm wea
ther. The shaft will be of Tobin bronz
. and the propeller and its featherng gea
, will be OF Manganese bronze. The engin
will be operated by gas generated In

, easily 1870 pound OF anthracite pea Goa
per hour. producing a hxed well-cleane
y gas. containing so per cent, OF the hea
units possessed by the coal The vesss
: will carry "a tons Of coal In her bunker,
which will give her a cruising radiu
E OF 100 miles at a speed Of six knots.
