Public Works Administration (PWA) allocated $80,000 to the 
Department of Agriculture for control work. 
Needs. —TVhe initial planting of the grounds included an Itco- 
logical Section (near the Rock Garden), and an Economic Gar- 
den. [or lack of curatorial oversight and gardening labor, these 
two sections have been abandoned for some time. It is important 
that they should be rehabilitated. The newly graded area north 
of the Japanese Garden affords a suitable area for a new location 
Sn BY 
for the Economic Garden. 
Several permanent supports are needed for vigorously growing 
vines. Mr. Caparn has prepared a design and specifications for 
a trellis and pergolas for the Silver Leaf (sletinidia). 
North Addition —The greatest need is the landscaping of the 
North Addition. (See page 20.) 
INTERNATIONAL SEED [EXCHANGE 
The systematic interchange of seeds between the United States 
and other nations (through both official and private channels) 
dates from the very beginning of this nation. After Thomas Jef- 
ferson returned to America from France, where he had repre- 
sented the new United States of America, he began sending his 
trench friends seeds of native American plants, receiving from 
them the seeds of French plants in return. This interchange con- 
tinued for some twenty-three years. 
* By his desire, our Consuls in every foreign port, collected and 
transmitted to him seeds of the finest vegetables and fruits that 
were grown in the countries where they resided. These he would 
distribute among the market-gardeners in the City | Washington | 
not sending them but giving himself and accompanying his 
gifts with the information necessary for their proper culture and 
management, and afterwards occasionally calling to watch the 
progress of their growth. This excited the emulation of our horti- 
culturists, and was the means of greatly improving our markets.” ? 
In 1933 we exchanged seeds with 207 other gardens located in 
50 countries, receiving a total of 2,525 packets of seeds of their 
native plants and sending in return 4,367 packets of seeds of na- 
tive American wild flowers and other plants.
