The beautiful school garden shelter house, given by 
Mrs. Frederick Ferris Thompson by her contribution of 
$4,000 for this purpose in 1917, was completed during the 
summer, after much delay in obtaining roofing tiles; 
path approaches to this building, aggregating over 1,000 
lineal feet, were built by an unexpended balance of this

immediate vicinity. 
Cooperation with the International Children’s School 
Farm League, providing instruction in gardening, was 
continued in the spring, until Mr. Henry G. Parsons,

John K. Small, under the highly appreciated patronage of 
Mr. Charles Deering; in Colombia by Dr. Francis W. 
Pennell, in cooperation with Dr. Rusby’s expedition for 
the investigation of medicinal plants; and in Ecuador by 
by Dr. J. N. Rose, of the Smithsonian Institution, who 
was aided by a grant from our Science and Education 
Fund. A very important cooperative arrangement for 
the investigation of the flora and plant products of northern

Museum; collections from that region will greatly enrich 
our greenhouses, museums, and herbaria.
