guards, and police for the care of the plantations, the preser-

The Museum 
A number of important repairs and alterations have been 
made in the museum, which improved the condition of the 
building and made possible an increase in the efficiency of 
several phases of the work of the Garden. The completion 
of the drain leading out from the subcellar of the lecture hall 
has resulted in a much drier condition of the entire basement 
of the building, and in an improvement of the sanitary con-

the uppermost floor to various points where needed, and the 
large aquarium in the physiological laboratory has been re- 
moved to the experimental greenhouse in order to facilitate 
some special investigations. ‘Two masons were employed in 
repointing the joints in the cornices and walls, in October, 
November and December, by which several bad leaks were 
stopped. This work was also extended to the balustrades, 
steps, and walls of the approach. 
No serious repairs having been made to the surfaces of 
the walls in the interior of the building since its erection, 
the painters were employed almost constantly during Sep- 
tember, October and November, in cleaning the surfaces 
and painting the same with a mixture of white lead and 
zinc. The phanerogamic herbarium, the cryptogamic her- 
barium, the hallways and rooms east of the Director’s office

to extend the method over the entire building. The upper 
part of the unused elevator shaft has been converted into a 
storeroom for the janitors. The photographic darkroom has 
been provided with large panels of orange and ruby glass in 
the door and overhead, which increases its usefulness. A
