REPORT OF THE SECRETARY. 45 
The division of plants received about 47,000 specimens, mainly from the fol- 
lowing sources: The West Indies, and especially Cuba, over 6,000 specimens; 
Central America, about 1,400 specimens ; Mexico, 2,200 specimens ; the Philippine 
Islands, 5,571 specimens; District of Columbia, about 5,000 specimens; from 
different localities, through the Department of Agriculture, over 4,000 speci- 
mens; the private herbarium of Mrs. J. N. Milligan, of Jacksonville, Ill., com- 
prising about 2,200 specimens; and the collection of the late Prof. T. A. 
Williams, numbering about 4,400 specimens. 
One of the most noteworthy accessions in geology consisted of a large amount 
of material obtained by the head curator during an investigation of Coon Butte, 
Arizona. The Geological Survey transmitted a large number of rocks and ores 
from Wyoming, Colorado, Washington, Arizona, and Maine, and material of 
the same character as well as minerals were obtained from other sources. The 
collection of meteorites was increased by seven specimens. 
The additions in paleontology were exceptionally large and valuable, the 
more important comprising about 45,000 specimens from the Pre-Cambrian, 
Cambrian, and Ordovician horizons in the United States, transferred by the 
Geological Survey; the Pate collection of about 50,000 specimens from the 
Paleozoic rocks of the Mississippi Valley, and several hundred specimens from 
the Devonian of Missouri, both presented by the Hon. Frank Springer; the 
Nettleroth collection, containing practically all of the many types figured in 
that author’s Kentucky Fossil Shells; and an especially fine representation of 
the Silurian and Devonian faunas of Indiana and Kentucky. 
EXPLORATIONS. 
While no extensive field work was carried on directly by the Museum, sev- 
eral expeditions, both for collecting and observation, were made by members of 
the staff, as follows: Doctor True in Maryland, Doctor Stejneger in Virginia, 
Doctor Bartsch in North Carolina, Mr. Bean in Florida, Mr. Hahn in Indiana, 
Doctor Dyar and Mr. Caudell in California, Doctor Rose in Mexico, Mr. Maxon 
in Cuba, and Doctor Merrill in Arizona. Mr. Charles W. Gilmore, of the depart- 
ment of geology, was sent by the Smithsonian Institution to Alaska to search 
for the remains of large fossil mammals, while Doctor Bassler and Doctor 
Peale were detailed to field werk in conjunction with the Geological Survey. 
The explorations by which the Museum was mainly benefited were, as hereto- 
fore, those of the Geological Survey, the Department of Agriculture, the Bureau 
of Fisheries, and the Bureau of American Ethnology. Mention should also be 
made of the personal field work in the Philippines of Doctor Mearns, of the 
Army, and in Malaysia of Dr. W. L. Abbott; and also of the excavations by 
Doctor Fewkes at Casa Grande, Arizona, under a special act of Congress. 
CARE AND CLASSIFICATION OF THE COLLECTIONS. 
The reorganization of the osteological collection in physical anthropology, 
which comprises parts of about 8,000 skeletons, was ccouipleted during the year. 
Doctor Hrdliéka, the assistant curator in charge of this division, has carried 
on investigations relating to the crania and skeletons of Indians and the 
orang, and to the brain in the higher vertebrates, including man. An exten- 
sion of storage space has permitted the classified arrangement of a much greater 
number of objects of ethnology than heretofore. Professor Mason and Doctor 
Hough were mainly occupied in working up the ethnological collections from 
Malaysia, and the latter also continued the preparation of his report on the 
Museum-Gates expedition of 1905 in Arizona, and on the Pueblo collections in 
the Museum. Doctor Casanowicz has begun a descriptive account of the exhi-
