The United States geological survey, or 
exploratory expedition, under the direction 
of Professor r R V. Hayden, United States ge¬ 
ologist, will be ready to take the field as soon 
as the season is sufficiently far advanced to 
admit of explorations in the mountain dis¬ 
tricts. Mr. James Stevenson, Professor Hay¬ 
den’s principal assistant, who, from an ex¬ 
perience of many years in the territories, is 
specially fitted for the charge assigned him, 
has been here for some time past, and is at 
present engaged in securing an outfit and 
making other necessary preparations for the 
start. Mr. Gardner is also here, supervising 
and arranging, and Hayden is expected to 
arrive between the first and middle of June. 
The men are at present encamped on the 
Fisher farm, on Clear creek, about five miles 
from Denver. 
The expedition will consist of three scien 
tific parties, each under the charge of geolo¬ 
gists and topographers conjointly, and th° 
three divisions are expected to cover an area 
of thirty-two thousand square miles. In ad¬ 
dition to the above, there will be a fourth 
party, a supervising force, of which Profes¬ 
sor Hayden and Mr. Gardner will be princi¬ 
pals. Mr. James Stevenson, apart from his 
office as disburser of all funds,, will have 
charge of the supply train, together with a 
large number of teamsters, laborers, cooks, 
hunters, etc., and will superintend the pro¬ 
visioning of the different parties. 
Mr. Jackson, photographer, and Messrs. 
Moran and Holmes, artists, the former 
a distinguished worker in water-colors, 
and who accompanied the party to the 
Yellowstone last year, will secure studies of 
the most remarkable scenery. One of Mr. 
Moran’s studies, a scene in the geyser region, 
a large-sized oil painting, has attracted no 
little attention at Washington, where it mey 
be seen in the statuary hall of the capitol 
building. Mr. Holmes, though yet a young 
man, is an artist of considerable talent, and 
gives promise of increasing excellence. 
One party, of which Dr. Peale, of Phila¬ 
delphia, is geologist, and Henry Gannett 
topographer, with several assistants, and 
Mr. Batty, of New York, as ornithologist, 
and teamsters, cooks, etc., will leave Denver 
about June 1, proceeding direct to Granite, 
in Lake county. This will be known as the 
South Park division. The party will extend 
their explorations as far east as Pike’s Peak 
and the foot hills, as far south as the Sa- 
| guache country, and west- to the Elk Moun¬ 
tain range. They will ascend, correctly lo¬ 
cate, and accurately measure, by barometric 
observation, all the principal peaks in the 
district named, many of which have so far 
been only approximately located on the 
f man Thesf* p'-nlo-ntions areexneetfid to fur¬ 
nish the data for a reliable geological and to" 
pographical map of the region. 
Another party, in charge of Mr. Marvin, 
geologist, and Mr. Lewis Bechler, topogra¬ 
pher, with the necessarylfessistants, packers, 
teamsters, etc., will be sent, but not before 
the middle of June, into the northwest dis¬ 
trict, which embraces th^hcountry west from 
Long’s peak to Home peak, on White river, 
north to the fortieth degree of latitude, and 
east to the edge of the plains. We are prom¬ 
ised an exact measurement of Long’s peak, 
and photographic views of its awful chasms, 
some of which equal, if in some respects they 
do not surpass, the famous Yosemite. The 
Middle and North parks will be included in 
the territory to which this party is assigned. 
The third division, which will occupy a 
more advanced field than the others, and 
consequently have a more important task be¬ 
fore them, is to be dispatched about July 1, 
and will take the western district, embracing 
the valleys and cafions of the Blue, White, 
Grand and Green rivers, and a large strip of 
Utah. Dr. F. M. Endlich, a thoroughgoing, 
industrious geologist, from Beading, Penn¬ 
sylvania, has supervision of the party, sec¬ 
onded by able assistants. General E. Ives, 
at the head of a small party, was dispatched 
through there ia 1855, under government 
auspices, but since then no official reconnois- 
ances, in the interest of science, have been 
made in that direction. Hence these explora¬ 
tions must prove interesting and instructive_ 
Dr. Endlich, before proceeding to occupy 1 
this field, however, will leave, in fact, left 
, yesterday, for the mountains, to examine and 
j report upon the mines, at Caribou, Central, 
Idaho, and Georgetown, and it is probable 
that, before returning to Denver, he will ex¬ 
tend his observations to the mining district 
about Fairplay. 
Extensive collections in geology, mineral¬ 
ogy, botany, and natural history, will be 
made, and these will be forwarded to Wash¬ 
ington, and there deposited in the United 
States National Museum, a feature of the 
Smithsonian Institution, to the collections of 
which Hayden’s various expeditions have 
added so largely. Mr. John M. Coulter, a 
botanist of acknowledged efficiency, will 
have charge of that department during the 
forthcoming campaign. There will be, prob¬ 
ably, with each division of the survey, one 
or more correspondents, some of whom are 
accredited from the leading journals of the 
east—journals which recognize the import¬ 
ance of the surveys in the development of 
onr territory. Of course, the unknown but 
marvelous region to be explored by the ■ 
Endlich party, will abound in facts for the 
correspondent with a nose for information. 
The three divisions or bands are instructed 
to return to Denver by the first of October. 
Here they will be disbanded, and the scien- J 
tifio members will proceed to Washington, 
there to convert their notes into reports, 
which must be submitted to Professor Hay¬ 
den, and by him to the Department of the 
Interior. All reports will be ready for pub¬ 
lication about a year from this time.
