Water Supply 
Work was commenced in the autumn and is being con- 
tinued during the winter in providing the high pressure 
water supply needed at the mansion, referred to in my 
last annual report, designed to provide running water on 
the third floor of that building; the increased use of the 
mansion for instruction of convalescent soldiers and of 
civilians in gardening makes a better water supply neces- 
sary. We purchased the 4-inch water pipe necessary and 
have done most of the earth excavation for the trench; 
rock excavation for a distance of about 100 feet is in 
progress and we hope to complete the principal connection 
within a few weeks; a short connection requiring 3-inch 
water pipe at the mansion still needs a few days’ work. 
Buildings

central display greenhouse and the orchid greenhouse 
added to conservatory range 2 through the gifts of Messrs. 
Daniel Guggenheim and Murry Guggenheim, and to the 
reoccupation of the other greenhouses of this range, which 
were closed for over a year by reason of coal shortage; 
necessary repairs were made to the roofs of the older 
houses of this range. Much repair work was found 
necessary at conservatory range I, including painting, 
replacement of glass, reconstruction of benches, and replace- 
ment of sash bars. Available funds did not suffice for com- 
pleting all repairs desirable and this work must be continued 
during the coming year. At the propagating houses, some 
absolutely necessary repair work was done, but all the 
plant benches in these houses need replacement in con- 
crete, which we are proceeding to accomplish as soon as 
possible; some painting is also required here. 
he museum building required repairs to the roof and
