It is hoped that the exploring party can be landed at some point 
on or near the shore of Lady Franklin Bay in time for the Gu- 
nare to return home this season. The Gulnare is being fitted up 
for ice navigation under the superintendence of Capt. Chester, 
who was with Hall in the Aolaris. A house of wood, double 
boarded, 21 x 68 feet, modeled after those used by the Hudson’s 
Bay Company, is being constructed for the men to winter in on 
the shores of Discovery harbor. A steam launch will probably 
form part of the expedition. The purposes and intentions of this 
new attempt at Polar discovery are given in the report of the 
House Committee as follows: 
“In making this report the committee respectfully state and 
report that the object of the bill, as is shown by its terms, is to 
authorize a temporary station to be selected within the Arctic 
circle, for the purpose of making scientific discoveries, explora- 
tions, and observations, obtaining all possible facts and knowledge 
in relation to the magnetic currents of the earth, the influence of 
ice-floes therefrom upon the winds and seasons, and upon the 
currents of the ocean, as well as other matters incidental thereto, 
developing and discovering at the same time other and new 
whale-fisheries, now so material in many respects to this coun- 
try. It is, again, the object of this bill that this expedition, 
having such scientific observations in view, shall be regularly 
made for a series of years, under such restrictions of military dis- 
Cipline as will insure regularity and accuracy, and give the fullest 
possible return for the necessary expenditure; and, again, in view 
of the fact that either the governments directly, or scientific corps 
under their authority, of Germany, Holland, Norway, Sweden, 
Austria, Denmark, and Russia, have concurrently agreed to 
establish similar stations, with like object, during the year 1880, 
it is believed that the interests and policy of our people concur in 
demanding that the United States should codperate in the grand 
efforts to be thus made in the solution of the mysteries and secrets 
of the North Polar seas, upon which, in the opinion of scientists, 
depends so much that affects the health and wealth of the human 
race,”
