from the White River Bad Lands and
from the Pierre shales of the Cheyenne
river. The wall cases are for large speci-
mems Of all classes and in these somewhat
less attention is given to scientific CLASH
hcatlon and more to such arrangement as
may bring out attractive features.
Among the more important specimens in
the museum, the following are worthy of
mentions: A polished and nicely etched
specimen Of Toluca meteorite weighing
three pounds, a sawed specimen of stream
tin weighing three and one half pounds, a
water or ice worn pebble of native copper
weighing five pounds, a polished specimen
OF gray granite traversed by sharply defined
dikes of black basalt, a polished specimen
OF chiastolite schist, a basaltic column from
the Rhine valley, lava medallions from Mt.
Vesuvlus, lava bombs from Utah and Mt.
Pelee, a large fossil fish from Green river,
Wyoming, leaf impressions from Illinois
and Kansas, a model of the largest known
birds egg, a beautifully preserved specimen
OF fossil Eurypterus also models of Euryp-
terus and Hughmilleria both of which are
closely allied to the trilobites, a set of sixty
models OF precious stones cut and colored
as IN the originals, models of four famous
diamonds, a model Of the magnificent
"Welcome" gold nugget found in Aus
tralla in 1858, the value of which was
$41,883, and a model of a twenty one
pound platinum nugget found in the Urals
in 1921. In addition to these specimens
certain collections from the Black Hills
region are noteworthy, namely, uranium
minerals from the Northern Hills, lepidolite,
rose quartz, and actinolite from near Gus
ter, s%iliceous calcites from the Pine Ridge
Indian Reservation, turtles, titanotherium
bones and a crocodile snout from the Bad
Lands, ammonites, %scaphites and Faculties
from the Cheyenne river, %selenite crystals
from the, eastern foot hills, calcites and
aragonites from the various caves, a series
OF we'll trimmed specimens of igneous and
sedimentary rocks and a representative col
lection of the various Black Hills ores,
Upon the walls there are maps of various
mining localities of interest such as Mesabi.
Leadville, Comstock and New Almaden.
Other maps, Of interest in the study of
photographic geology are the Grand Can
yon, Lake Of the Woods, Steamboat
Springs and Mount Rainier. There are
also plates Of mammals, reptiles and toothed
birds. Besides these, there are several
economic charts, the work of students in
economic geology which show the gold,
silver, copper and iron production Of the
states and Of the world. A fine model of
the Black Hills region on deposit with the
School fills an important place.
1t may be readily observed that the mu-
scum is we'll adapted to the needs of the
student and effort is being made to place it
in the best possible condition for constant
use. Specially constructed display trays
have been secured for the various collections
and as time permits, all of the specimens
will be clearly tabled. There are many
needs, many vacancies in the collections
the hasty observer might not detect. This.
however, is characteristic Of any artificial
display Of natures resources and in a
measure must grow as the display grows.
Many individuals, students, instructors and
visitors, have shown their appreciation o
the Importance of the museum by sending
or bringing specimens Of value. It is to
be hoped that this disposition may become
more and more prominent. The Black
Hills collections, especially, could be easily
and materially enhanced in value and use
fulness by additions in this manner. The
Black Hills display, as already indicated, is
a very worthy one and it is hoped that in
time it may become Of far-reaching sig
nifcance.
Effort is made to have the museum open
for inspection during all school hours. Up
town and out-of-town visitors are always
welcome. The room is an attractive one
and to those not familiar with geological
phenomena in their more prominent
