been particularly fortunate in the amount of 
field-work which it has been able to carry on during the year. 
Messrs. Wharton Huber and J. Fletcher Street visited Nicaragua 
in the interests of the institution, and secured valuable collections 
especially of birds, mammals and insects. The travelling expenses 
of this expedition to Bluefields and back were generously subscribed 
by members of the Academy; and during their stay in the country 
the members were the guests of Dr. Theodore E. Bouchell and the 
officers of the Tonopah Mining Company, who did everything in 
their power to aid them in carrying on their work. Mr. J. A. G. 
Rehn was enabled to join Mr. Morgan Hebard in another recon- 
naisance of parts of California and Arizona for the collecting of 
Orthoptera, the Academy sharing with Mr. Hebard in the material 
obtained. Dr. H. A. Pilsbry spent three months (September to 
November) in the eastern ranges of New Mexico and the Big Bend 
region of Texas, collecting mollusca in the San Andraes, Organ, 
Sierra Blanca, New Mexico, and the Guadalupe and Chisos ranges 
of Texas. The object of this trip was to map the eastern limits of 
the characteristic desert groups. Mr. Rehn’s and Dr. Pilsbry’s 
expenses were provided for by members of the Academy. 
Dr. Francis W. Pennell, cooperating with the N. Y. Botanical 
Garden, the Gray Herbarium, and the U. S. National Museum, 
headed an expedition to the Colombian Andes for the purpose of 
continuing his botanical researches in the region, and secured some 
23000 specimens, which the Academy shares equally with the other 
institutions, in return for Dr. Pennell s services. He had as his 
field associates Mr. E. P. Killip, of Washington and Dr.T. L. Hazen, 
of Columbia University. 
Air. Henry W. Fowler, in the same way, is securing for the AIus- 
eum a very valuable series of Pacific fishes in return for determining 
the collections in the Bishop Museum in Honolulu, his expenses 
being covered by the award of a Yale University Pacific scholarship. 
He left on August 1, and will return in April of next year, spending 
some time in collecting desirable material on the coast of California. 
Realizing the imperative need for additional cases for housing the 
study collections in various departments, and funds to carry on 
several of the expeditions just described, the Curators were author¬ 
ized by the Council to endeavor to raise funds for the purpose, and 
thanks to the generosity of our members, a sum of over $5000
