TRENTON. June A, S90.-Arrangements
have been completed by which a NUMBER
Of scientific expeditions will be sent out
from Princeton shortly after commence
ment. to devote the vacation in inyesti-
eating the waters in parts of the ocean
and explore some regions of the West.
Professor Scott, of the Geological De-
partnent of the college, will conduct an
expedition which will make scientific ex-
plorations in Southwest Dakota ana
Northwest Nebraska. The most OF ths
work of the expedition will be connued
to the tertiary fossil beds of Loop ForK
and White River. The party will leave
Princeton in July, and will proceed %
Fort Robinson, whence they VIII con
tinue their journey on horseback ana un'
der cover OF tents.
composed of G. b.. Agnew, OF New IorKs
A. b. Gladwin. of New Jersey; r. A. ..
Lewis, of New Jersey; Charles Mixer, OF
Illinois; c. r.. Agnew, quartermaster, %
New York, and r. I. Lyon, treasurer, OF
New Jersey. all OF whom are emDers Of
the present junior class of the college.
Prof. Libbey, of the Department. OF
Physical Geography and Histology. IS
also at the head OF expeditions which are
to make several important lnVeStlgatlons
in the interest of science and the Unlteq
State Fish Commission on Long Island
Sound and in the Gulf Stream. He VIII
be accompanied by L. w. Nudge, %,
Prof. lockwood and Allen Harris. w OF
Princeton, and Pro. McNiel. OF Lake
Forest University, and Il. T. Btgelow, OF
Johns Hopkins. The party will sail july
/, on the coast survey steamer Blake ana
the Grampus. They will make g pnysl-
cal investigation OF the mackerel regions
Off the New York and New England
coasts. Meteorological observations VIII
also be mace.
AS the mackerel food lies on the sur-
face. and it's location is determined py
winds. currents and the temperature,
which are the objects of the investiga-
ton. It is believed that the discoveries
made will be of great practical impor-
lance to the fishing interests. Prof. LIB
hey. from his study Of the photographic
maps. expects The Gulf Stream TO lie
near the coast. as it did last summer.
The specific questions which Will pc
the object of the Investigations are:-Ihe
limits Of areas of equal temperature and
OF equal specific grAvities, and the effects
AZ produced upon these by currents ana
wihdsf Does the Gulf Stream perma-
nently intrude upon the continent plat
form, or was it only blown In by the
winds last summer? Does the polar cur
rent dip under the Gulf Stream?
Al station will be established on the
New South Shoal Lightship, about TWEEN
ty miles off the southeast coast OF Nan
tucket Island. This will be in charge of
S. r. Dodd, instructor at Princeton; John
Zimmerman, 100, and w. III. Dodd, '9S.
Here the water temperature will be taken
hourly and a running account OF air, tenn
perature, winds and atmosphere
cal electricity will also be kept. A strict
observation will be made Of the tidal cur
rents, which will be of great Importance
in settling the vexed question of the
influence OF the defamation of the moon
on the tide. The best instruments obtain
able have been provided for making the
observations, which will probably prove
the best and most thorough investigation
of the relations between warm and cold
currents, and the effects OF these and the
winds cn the distribution of fish food that
have ever been made.
Mr.. Frederick Neher, '89, of Princeton,
under the supervision of Prof. Libbey, will
also head an expedition which will make
a chemical investigation of the waters OF
Long Island Sound, with q view to ascer-
tanning the chemical condition of the
water on the oyster beds. Prof. Libbey
has already given the matter some atten-
ton, Ind Is of the opinion that the de-
struction Of the oyster beds is not due to
the starfish, for in dredging sufficient
numbers OF theM I've never been found,
but attributes it to the refuse in the
water, which O tidal wave in the Sound
prevents from passing OF out into the
ocean.
