pleted on October 21. The new work increases the capacity of 
our coal cellar by about 137 tons, to a total of about 430 tons for 
No. 1 buckwheat. This gives us a much larger factor of safety in 
the matter of being able to have enough coal on hand to tide over 
long periods of stormy weather in the winter, or other times when, 
for one reason or another, deliveries can not be made. A period 
of 26 months elapsed from the date when the first request for the 
appropriation was forwarded to the Board of Estimate and Ap- 
portionment to the date of beginning the work—over two years 
and four months to the completion of the work. 
Private Funds.—The total private funds income for the year 
was $34,726.01, an increase of $679.15 over 1920. Of this amount 
$19,230.46 represents income from permanent endowment, the re- 
mainder being derived from several fluctuating and more or less 
uncertain sources, varying in amount from year to year. There 
have been expended $29,139.50 of private funds. 
Endowment Increment Plan—The most important financial step 
in the brief history of the Garden was the adoption by the Gov- 
erning Committee, at its meeting of January 11, 1921, of a plan 
for Endowment Increment, substantially as recommended in the 
preceding annual report of the director. This plan provides for 
increasing the principal of Botanic Garden endowment. by annual 
increments from income from certain endowment and other private 
funds, restricted by terms of gift, bequest, or otherwise to the edu- 
cational and scientific work of the Garden. The plan was adopted 
for the year 1921, beginning as of February 1, and until action is 
taken to the contrary. It was voted to create a new account to be 
known as “ Endowment Increment Account,” and to make trans- 
fers to this account to the amount of 20 per cent. of the annual 
income from the various funds included in the plan. During the 
year $4,876.22 were thus added to the permanent funds of the 
Garden. The amount thus to be transferred and invested will 
increase each year, and the plan can be carried out without seri- 
ously curtailing our educational and scientific work. In fact, 
within a very few years the available income for these purposes 
will be much greater than could be possible without such a plan, 
and it is a great pleasure to look forward fifty or a hundred years
