December 1st—when bis duties became associated with the Depart¬ 
ment of Geology—remains much as it was at the time of the filing 
of the last annual report. As for a number years past, the one 
great obstacle to arrangement and classification in the deficiency 
of exhibition-room and cases ; indeed, at the present time, there is 
even less room than heretofore, owing to the necessary division of the 
main hall into a section devoted to entomological interests. Only 
with occupancy of the new hall can proper relief be expected. 
The usual spring course of lectures has followed as a continua¬ 
tion of the courses of past years, and it is gratifying to be able to 
report that the attendance has been steadily increasing year by year, 
the enrolled students for the past season numbering 116. Emphasis 
is again laid on that portion of the instruction which is associated 
with field-work, when an opportunity is given to examine practically 
much of that which is first illustrated in the class-room. In addi¬ 
tion to the regular Saturday field-parties, the course included, for a 
limited number, an examination in the month of August of the 
Rpcky Mountain region, when the practicability of so extended a 
class-excursion was clearly demonstrated. The region studied com¬ 
prised sections of Colorado, Wyoming, Utah and New Mexico, and 
specifically the Pike’s Peak district, gold mines of Cripple Creek, 
“ bad lands,” Great Salt Lake, canons of the Price, Grand and 
Arkansas Rivers, the volcanic masses of the San Juan, etc. 
As Professor of Geology, the undersigned would respectfully 
recommend, the disposition of the geological materials of the 
Academy, space in the new hall, and that enough of it be given 
for that form of display which is now a part of the method of almost 
every new museum. A geological exhibition means not merely a 
display of rock specimens for themselves, but illustration of the 
dynamics and economics of the science. Therefore, sections of rock- 
strata, models of geological structure, well and coal borings, etc., 
are eminently necessary for a proper or modern exhibition. 
Respectfully submitted, 
Angelo Heilprin, 
Prof, of Invert. Paleontology (to Dec., 1895), 
now Prof, of Geology.
