32 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1919. 
cal collecting by himself and associates among the Christian Brothers. 
The collection of Philippine plants was greatly increased by the ad- 
dition of two lots, aggregating more than 9,600 specimens, one 
received in exchange from the Bureau of Science, Manila, the other 
acquired by purchase. The South American series was also aug- 
mented considerably by the donation of 1,761 Venezuelan plants by 
Dr. H. Pittier and 1,077 specimens exchanged with the Museu Goeldi 
in Para, Brazil, besides the Museum's share of about 2,000 specimens 
from the Ecuadorean Andes collected by Dr. J. N. Rose on an 
expedition undertaken jointly with the New York Botanical Gar- 
den and the Gray Herbarium; while exchanges with the last-men- 
tioned institution added approximately 1,450 more South American 
plants. 
The exhibition collections were closed most of the year on account 
of the space having been turned over to the Bureau of War Risk 
Insurance. However, toward the end of the jea,r the halls on the 
first floor, containing mostly the mammals and birds, including the 
great biological groups, were reoccupied by the Museum and opened 
to the public, after certain additions and improvements in the in- 
stallation had been made. 
Geology. — The additions to the collections in this department 
during the year were but 135 lots, aggregating an approximate total 
of nearly 31,000 specimens. This number, although somewhat less 
than that of the preceding year, is, in part, compensated for by the 
unusual value of sundry individual specimens. Among these may be 
mentioned examples of tungsten minerals both from domestic and 
foreign sources, including a magnificent specimen of scheelite pre- 
sented by Dr. J. Morgan Clements, of New York City, and upward 
of 16.5 kilograms of the extraordinary meteorite which fell at Cum- 
berland Falls, in Whitley County, Ky., on the 9th of April, 1919. 
The availability of the Frances Lea Chamberlain fund has enabled 
the department to begin once more a systematic building up of the 
Isaac Lea gem collection. A 7-gram kunzite, a 16-gram black opal 
from Nevada, and 5 beautiful examples of Australian opals of a 
variety heretofore unrepresented in the collections are among the 
more important additions. 
The Middle Cambrian collections obtained by Secretary Walcott 
from Burgess Pass in British Columbia number nearly 7,000 indi- 
vidual specimens, and form an addition of unusual value. The 
same is true of a collection including both fossil invertebrates and 
plants, mainly from Carboniferous and Silurian rocks of Indiana, 
and especially rich in beautifully preserved crinoids. This collec- 
tion, comprising not less than 10,000 specimens, was a gift of Mr. 
Alva Schaefer, of Brazil, Ind.
