from various points in tropical America at such time as 
this becomes practicable. 
21. Propagating and Experimental Greenhouses 
In order to conserve fuel, two of the four greenhouses 
of this range were emptied in the autumn, partly by the 
elimination of duplicates and partly by transferrals to 
conservatory range I. One of the two houses in operation 
contains parts of our extensive collection of cactuses, most 
of which, when conservatory range 2 is in operation, it is 
planned to move to conservatory range 1. Only ordinary 
repairs have been required for these buildings. 
22. Natural Features 
The natural beauty of the reservation remains unim- 
paired. Some dead and decrepit trees have been cut out 
of the woodlands and used for fuel and fencing, and this 
work is in progress at the present time. As a whole, how- 
ever, the trees are in excellent condition and the amount of 
dead wood within the reservation is very small. Our 
patrol against fire and vandalism has been effective, but 
it is only that which has preserved the woodlands from 
serious damage, inasmuch as a considerable number of 
fires have been started, either accidentally or maliciously. 
It is still desirable to extend the railings along trails in 
various parts of the woodlands, in order to restrict travel 
to well-defined lines, but the cost of iron during the past 
year has made this extension impossible to secure, and 
wooden railings have been found altogether unsatisfactory, 
being subject to rapid decay and requiring high expenditure 
for repairs. 
The income of the fund for the preservation of native 
plants, given some years ago by the Misses Caroline and 
Olivia E. Phelps-Stokes, has been allowed to accumulate. 
It is proposed to use this accumulation, added to the income 
of the fund for 1919, for the reproduction of additional 
colored illustrations of wild plants requiring special pro- 
tection.
