Work has necessarily been mainly confined to caring for the 
accessions. Miss Ada Allen has continued with the mounting of 
the specimens and has prepared for cataloguing and distribution 
3,150 sheets. Mr. Van Pelt has mounted all accessions to the local 
collection, amounting to 3,114 sheets and including 664 from the 
Porter herbarium, which have been distinctively labelled in accordance 
with the agreement with Lafayette College, by which institution 
they were deposited. 
Mr. Long has distributed and identified material added to the 
local herbarium and made critical studies of various groups. He 
has also attended to much correspondence in connection with the 
general collection. 
The herbarium has been consulted during the year by Dr. C. S. 
Sargent, W. W. Eggleston, Harold St. John, Francis Pennell and 
many others, anti specimens have been loaned to W. W. Eggleston, 
P. C. Standley, Dr. R. H. Howe, Dr. J. C. Arthur, K. K. McKenzie, 
B. H. Smith, Dr. C. S. Sargent, Dr. F. Pennell, Harold St. John, 
Dr. J. M. Greenman, Prof. M. L. Fernald. 
The collection of trunk sections of native trees of the Alleghanies 
presented by Mr. C. H. Jennings has been prepared for exhibition 
and placed in two mahogany and plate-glass cases in the mineralogical 
hall just outside the entrance to the herbarium, where it attracts 
much attention. 
Minerals and Rocks. 
Mr. S. G. Gordon, under the direction of Mr. Frank J. Keeley, 
Curator of the William S. Yaux Collections, has completed a check 
list of minerals according to the sixth edition of Dana’s Manual 
as an aid in the rearrangement of the collection which will be under¬ 
taken during the coming year. 
Several of the cases in the hall were rearranged and part of the 
specimens transferred to cases presented by the Curwin Stoddart 
Estate. 
Mr. Gordon has also redetermined most of the rock specimens 
and in part relabelled thejn, while many minerals in the general 
collection have also been redetermined. Many members of the 
Geological Society of America took occasion to examine the collec¬ 
tions during the annual meeting of the Society at the Academy, in 
December, 1914.
