PrersonaL Activities, Honors, AND ACHIEVEMENTS 
OF THE DIRECTOR 
! 
A complete list of the published writings of Dr. Gager would 
contain more than three hundred titles. Some of these were tech- 
nical contributions to botany; others were concerned with botanical 
education ; and a very large number were short articles dealing with 
the Botanic Garden, and book reviews. 
Dr. Gager edited the publication of thirty-two annual volumes of 
the Brooklyn Botanic Garden Record, which was founded in 1912, 
One number of each volume was devoted to the Annual Report of 
the Garden’s activities. Other numbers included the Prospectus 
of courses for the educational work, the publication of special fea- 
tures of the Garden, including the Guides to The Japanese Garden, 
Rock Garden, The Story of Our Boulders, The Story of Fossil 
Plants, The Rose Garden, Local Flora, Herb Garden, and the 
Medicinal Plant Garden. In the Annual Reports of the Director, 
Dr. Gager reviewed the activities and accomplishments of the Gar- 
den. Some of the special numbers were written by him, or with his 
active cooperation. 
In 1908, Dr. Gager published an extensive paper on the effect of 
radium rays on plants. His interest in the evolution of plants led 
him to translate and publish, in 1910, /ntracellular Pangenesis, by 
Hugo deVries. In 1916, he published his first text book Punda- 
mentals of Botany, and in 1926, another text, General Botany with 
Special Reference to its Economic Aspects. 
For many years Dr. Gager was engaged in compiling data for the 
publication of Botanic Gardens of the World: Materials for a His- 
tory. The first edition appeared in 1937 and a second in 1938, in 
the Botanic Garden Record. Data concerning more than 550 bo- 
tanic gardens in eighty countries were included. Dr. Gager had 
visited some of these gardens in 1927, when he made an inspection 
of gardens and botanical institutions in seven countries in Europe. 
Again, in 1930, when he attended the Ninth International Horti- 
cultural Congress in London, and the Fifth International Bo- 
tanical Congress in Cambridge, he spent some time visiting Euro- 
_ 
—e 
pean botanical gardens.
