REPORT OF NATIONAL MUSEUM, 1914. 79 
constructed under contract, the remainder being built in the Museum 
shops, which were also called upon for much miscellaneous and repair 
work. A number of old cases and other articles which had outlived 
their usefulness were condemned and disposed of. An inventory of 
the furniture on hand at the close of the year records 3,561 exhibition 
cases, 6,848 storage cases and pieces of laboratory furniture, 3,361 
pieces of office and miscellaneous furniture, 40,056 unit specimen 
drawers of wood, 4,/12 unit specimen drawers of steel, 8,439 insect 
drawers, and 19,751 miscellaneous specimen drawers and boxes of 
various kinds. 
A decision having been reached as to a form of curtain suitable 
for the large windows in the exhibition halls in the new building, 
such as were most urgently required were installed during the year. 
The necessity for the use of curtains arises from the failure of the 
ground glass to sufliciently protect the colors of specimens, more espe- 
cially in the zoological and ethnological exhibits. Difficulty was 
-encountered because of the exceptionally large size of the windows 
and of the fact that each contains two large movable panes near the 
bottom which require to be kept open in warm weather. In accord- 
ance with the system adopted, the main curtains on the first floor, of 
unbleached muslin, reach from the window top to the upper level of 
the ventilating openings, and are followed by shorter curtains cover- 
ing the lower part of the windows. In the second floor, however, the 
curtains, also of the same material, extend continuously the entire 
length of the window. All are hung on nickel-plated brass rods and 
are in pairs, with a simple device for pulling them to the sides. 
Curtains of this character were installed on the south and west sides 
of both floors west of the south pavilion and in the court windows 
adjoining the collections of zoology and ethnology. In addition, and 
as a very necessary protection for the mammal and bird exhibits, thin 
black curtains were introduced between the muslin curtains and the 
glass surface of the windows on the first floor of the west wing and 
on both sides of the adjoining range. These black curtains, which 
practically cut out all of the light, are not intended to be used until 
after the time for closing, or from 4.30 o’clock in the afternoon until 
9 o’clock in the morning, during which period for a considerable part 
of the year the sun’s rays continue effective during several hours. 
It was also found necessary to provide cambric shades for the win- 
dows in the north west range of the older Museum building, contain- 
ing the period costume collection, in order to prevent the fading of 
the delicate tints in many of the fabrics there displayed.
