THE SEASON OF SURVEYS.


A correspondent OF the New York
Times has recently spent an hour
among the savans at Washington, and
learned something of the work the
scientists are to do this summer in Col
orado. This season, says this corre-
spondent, Professor Powell, the ex-
plOrer of the great canon of the Colo
/ RADIO, will survey the country from
Utah west 10 the lO9th meridian, which
is about the western limit of the ter
ritory allotted for Professor tHayden's
work.
IN HAYDEN's WORKING ROOMS.
was shown through the offices oc-
cupied byr Professor Hayden's assist
ants. Here we examined the mag
niicert series of Photographic views Of
I Colorado Territory, the water-color
sketches of the more remarkable poiHts,
the endless series of maps, show ing its
! Typographical and other natural feat
ures; the geological and mineral speci-
mems, and numerous other objects of
interest. Mr.. Holmes, who wilt COM
mand one of the divisions this season,
was found busy with his Typographical
sketches, and showed us u section of
large plan he is ut work upon, exhibit
ing the Rocky MOuntainsysteIn. The
material used was the ordinary sculp-
tors clay, and when finished it will
convey to the observer very complete
inca Of the country. 1t is, of course,
modelled to scale, giving the relative
heights of the peaks and ranges, the
courses of the rivers, and the more
prominent features of the region, with
the strictest scientific accuracy. 1t is
scarcely necessary to point out that the
models upon this plan will be among
the most valuable contributions to our
knywledge of the great territory they
represent. Leaving Mr.. Holmes rooms
call WAS next made on Mr.. Jackson,
who has charge of the Photographic de-
partment. The Odor of chemicals be-
came apparent IS one approached his
offices, and more strongly as the door
was thrOw WI open. The same readiness
and cordiality in displaying the inter.
esting objects aud giving information
which had characterized other depart
ments was shown here. Mr.. Jackson,
though our visit must have made
serious inroad on his busy hours, was
untiring in his efforts to make it profit
able 10 US. His shelves were loaded
with albums and sketch-bOOks, in the
window hung some beautiful photo
graphic transparencieS of mountain
scenery, scattered around the room
were the implements of his business,
and on the walls were suspened photo.
graphic views of all sizes, and in more
or less advanced stages Of progress
Conspicuous over all, were the rifles and
cartridge belt, with which every mem.
Der of the field parties seemed to be
provided. In another room gentle
man WAS engaged with some formid.
able calculations of something, aiti-
tudes, think they were. Before him
lay several sheets Of fOoiscap, couered
with figures; close beside these, an
open volume of Somebody's Logar-
ithms, with the help of which he was
making out the results. But this
fOrbare TO inquire about, for fear he
should attempt to explain the matter
to me. Utter cOnfusiOa and bewilder.
ment must have inevitably followed.
With this, and some other visits, our
rounds were completed, and the inn
preston carried away that Professor
Hayden's men were just the sort of fel-
lows one would most desire for COM
rades in mountain expedition.
The ground of this summers survey
by Prof. Hayden's party lies between
meridians l040 and 1902 30>, or from a
point about forty miles east of Denver
to the extreme western limit of Colo
RADIO, and north and south between
parallels 80 and 410, which mark the
northern and southern boundaries of
the territory. The expenditionary
corps will be divided into six divisions.
The first of these is called the primary
triangulatiOn party, and will be under
command of Mr.. Gardener. The main
lines of triangulatiOn are taken by him,
and are drawn from peak to peak, the
highest being selected for this purpose.
After him come the tOpographers, who,
working inside the lines laid down,
which sometimes have sides 100 Eliles
long, sel:ct the smaller peaks in the
designated area, and work down,
throwing the smaller triangles, and
mapping out the country. By this
method the work of survey is constant
ly progressing. The tielG divisions
have their outline maps ready when
they start out, and know exactly what
ground to cover and what Is necessary
to be done on it, while the primary
triangulati0n party is always ahead,
mapping out new work, which may be
done tho same season or the next, as
circumstances dictate. The system is
the same as that employed in the sur
vey of Switzerland, which was the
most perfect piece of work of its kind.
The tallest peaks are selected for the
great lines because they rise high above
the timber line, and present no OBJ
stacles to the sight.
THE SEVERAL DIVISIONS.
The survey corps will take the field
i'm six divisions, each with its allotted
territory for work. Some years ago
the whole corps kept together, but it
was found better to divide 1t in the
manner stated. Mr.. Gardeners party
will cover wide area, planning out
new work for the field parties; Mr..
Wilson's division will take the south
eastern portion of the territory; Mr..
Holmes the southwestern; Mr.. Can
nett's the northwestern, and Mr..
Bechler's the northeastern. Each of
these typographical and geological di-
visions will average six men to the
party-three or four scientific men, two
packers, and cook. Besides these
there is n Photographic party, under
Mr.. Sackson, who have no special field,
but travel over the whole area, taking
views of the various points of interest
and of such special objects peculiar to
the country as may seem desirable.-
This syear, however, their attention
will be devoted mainly to the Indian
