THE GEOLOGIC SURVEY.
Return Of the Explorers.

Several attaches of the Hayden Gardiner
seient;ic survey went East yesterday on the
Rock Island road after finishing up ,hei,
summers work. From the Rocky Noun
tain Aess We iearn that the party have been
engaged during the season in the geologic
and geode:ic sufv-. of Boulder, Gilpin and
Clear Creek COUNTIES. ,he snowy range wes,
OF them, and the Middle park aud its eur
rcundings. The work planned was finished
complete except = small district in the vicin-
ity Of Breckenridge. Cold and stormy
Weather Of las, week compelled suspension
| OF operations for the season, and the party
hurried out over the range via hamilton
The seasons operations have been very sat
isfaciOry, and the amoust Of work accom-
plished very large. Mr.. Marvine. geologisr,
Was in charge; Mr.. Beechier, chief topo-
grapher, and Mr.. S. B. Laid, assistant,
| with numbe. of laborsrs in varions capac-
lilies.
| Some of the most interesting discoveries
made this summer by DR.. Hayden's explor-
ing party are due TO the labors Of Professor
Cope in archaeological researches among
the Red Lands" OF Colorado The re-.
mains here are even more interesting than
in the similar gions OF Wy Oming. They lave
been found TO be a vast graveyard Of animals
belonging 10 losg past period Of the
earlh's exi-,euee. Up to the present
time, Professor Cope has proven the exist
ence oi more taau one hundred species, rep

They range tom the siz. @; the Iayie to
nearly that ~ ,he elephant. Sixteen spe-
cies are reptiles. Many forms oi inseciiyer-
Gus aniiiiais, related 10 the mole, and Of
| very small size have been procured. the
d.licicy and minUtencss OF these :oSsils IL
surprising. Gnawins animals, or rodents,
Lett numerous remains of eighteen species,
some no larger than the domestic mouse.
Some we're the predecessors of the rabbits,
some OF the squirrels, and some Of the
mice. OF ciosen-hoofed quadrupeds great
many have been found. Some were nearly
intermediate in structure between the dee.
and the hog. Like the latter, they had nc
horns. They were about as large ~ sheep
others were about the size Of gray squirrels,
being the smallest Of this class of animals
ever discovered. Several species of horse-
were living through the same period, as il
proven by the bones and teeth which hav,
been obtained. Their relatives, the rhino.
ceros, abounded in Colorado in former days
no less than seven species having beer
procured by Professor Cope.
In regard TO the mines discovered, the
Cogueite is asilver lode with three feet crew.
ice, one foot of which is yellow sul phurets, as
saying over $3.50 silver. The galena ores
have assayed as high AZ 81, Oo0 per ton, sam.
pied ore. Another lead, the ST. Lawrence
has n forty-feet vein, from twelve TO fifteen
;eet of which is galena, with sulpturets OF
copper the rest of tine distance. In places q
solid bed OF mineral is exposed to view enc
hundred feet wide. This is more than Elk
miles long. 1t will average Two hurdr d
and fifty-six ounces of silver.
Mr. Chase but adds his endorse ment to all
else that has been said relative to the rich
ness of the district from which these spCci-
mems are brought. Mountains of argenti.er-
Gus aud auriierous rock predominant, and
rieh leads are found on every hsnd. The
silver leads We have spoken OF are on the
same mountain a. the Little Giant, one of
the richest gold mines in tire world, and
the mountain is gridironed with leads. As
yet there are no reduction works for the sill
yer ores, but furnaces will be taken in next
summer. This done the miners will be able
to work their mines much more extensively
than al present.
Next year there will be 4 great rush to
these mines, and hundreds of leads will be
opened. Prospeciors and miners are going
in from all directions, and the section will
see an unprecedented activity.
