REPORT OF NATIONAL MUSEUM, 1914. LOT 
the skeletons of the two reptiles 7hescelosaurus neglectus and Allo- 
saurus fragilis, elsewhere referred to, were installed, the porpoise 
skeleton from Chesapeake Beach, Md., was temporarily placed, and 
a long wall case was utilized for partial skeletons of early mammals. 
In paleobotany the exhibit of fossil wood was improved by placing 
it in two long wall cases; several greatly enlarged photographs rep- 
resenting fossil forests of Carboniferous and Mesozoic age, and a 
number of large illustrations of restorations of Paleozoic plants, 
were added. : 
Explorations —The only field work of importance was carried on 
in connection with the division of paleontology, although the head 
curator made some observations in the summer of 1913 while col- 
lecting feldspar for the educational series, and briefly studied a 
pyroxenite occurrence at South Freeport, Me. 
Two explorations were conducted by Secretary Walcott during the 
season of 1913, one in the Robson Peak District of British Colum- 
bia and Alberta, Canada, the other at the celebrated Middle Cam- 
brian localities near Field, British Columbia. In both regions the 
investigations of previous summers were continued and rich col- 
lections of fossils, including a number of new genera and species, 
were obtained. The material brought to Washington aggregated 
about two tons of carefully selected specimens. The curator of the 
division, Dr. Bassler, spent several weeks of the summer in con- 
tinuation of his studies of the Cambrian and Ordovician rocks of 
western Maryland, completing the geologic mapping of this area ard 
securing many fossils. During July, under detail to the Geological 
Survey, he mapped the Hamilton and Mason quadrangles of south- 
western Ohio. In June, 1914, he made a trip through some of the 
Southern States, studying in detail the stratigraphy of certain Ter- 
tiary formations and collecting fossil Bryozoa required for the com- 
pletion of his monograph on this group. 
Under the direction of Mr. Frank Springer, Mr. Frederick Braun 
engaged in extensive collecting work during the season of 1913 in 
Illinois and adjoining States, with special reference to securing cri- 
noids from the Chester division of the Mississippian. The results of 
this exploration have enabled Mr. Springer to definitely correlate 
certain upper Mississippian formations in various regions which have 
hitherto been in doubt, and several excellent slabs of crinoids and 
blastoids, invaluable for exhibition purposes, were obtained. 
During six weeks of July and August, 1913, Mr. Charles W. Gil- 
more was detailed to the Geological Survey to enable him to collect 
Upper Cretaceous vertebrate fossils in the Blackfeet Indian Reserva- 
tion in northwestern Montana. Though the material obtained was 
not extensive in amount, it included a very valuable series of dino- 
saurian remains, none of which had previously been represented in
