An electrically operated machine (the Davis Bulletin) showing 
in succession various colored illuminated views and information 
concerning the Botanic Garden attracted much attention. 
The Garden’s exhibition at the United Parents Association Ex- 
position, Grand Central Palace, April 23-28, was similar, except 
that the booth was smaller: the central table with the evolutionary 
tree of the plant kingdom was therefore omitted. 
At all these expositions attendants from the staff of the Garden 
were continuously on duty explaining details to visitors. It is 
impossible to more than guess the number of visitors who saw 
the exhibits. The expositions were all well attended, so that 
probably the number of visitors exceeded 100,000. 
Leaflets 
As in former years, I have continued the editorship of the 
Leaflets.. Six issues, four of them double numbers, were pub- 
lished during 1928. The first three, No. 1, “ The story of plant 
evolution”; No. 2-3, “ How bacteria are studied in high school 
science classes ’’; and No. 4, ‘‘ How shall we save rare plant species 
from extinction,’ were printed in advance of the date of issue, 
for distribution at the two expositions as above stated. O. 5-7, 
“ Department of Elementary Instruction: A survey of work from 
1913 to 1928,” was printed in advance of the date of issue, for 
distribution at the Spring Inspection, May 8. No. 8-9, “ Bulb 
culture,’ was a third printing ef this popular subject, and No 
10-11, “ Practical suggestions on the growing of Christmas greens,’ 
was written in response to queries elicited by the Christmas Leaftct, 
last year—‘ What price Christmas greens?” To date (Jan. 31, 
1929) ninety persons, mostly residents of Long Island, have 
written to the Garden for copies of the leaflet on the growing of 
Christmas greens. 
Reprints. Ten years ago from 1,200 to 1,500 copies comprised 
a single issue of the Leaflets. Today 3,000 copies per issue are 
needed, primarily because of the increased membership in the 
Garden and the much longer list of exchanges; and also because 
of the greater demands of the schools for copies for distribution. 
Even with 3000 copies, popular, issues soon become exhausted. 
“ House plants,” for example, has been through three printings:
