On July 27, Dr. C. D. Jarvis, special collaborator of the U. S. 
Bureau of Education, Washington, D. C., who is conducting the 
course in children’s gardening at Teachers’ College, Columbia 
University, during the summer session, addressed our summer 
school class for teachers of children’s gardening. Dr. Jarvis took 
as his subject the “ Theory of Children’s Garden Work, and the 
Way the Bureau of Education is Meeting this Problem.” 
On July 31, Dr. Jean Broadhurst, of Teachers’ College, spoke 
to our summer class on “ Bacteria and their Relation to Canning.” 
After the lecture there was an informal reception to Dr. Broad- 
hurst. Members of Dr. Broadhurst’s own class at Columbia met 
here at 4:00 o’clock to inspect our children’s gardens and visit 
the Japanese and rock gardens. 
The Flatbush Garden League had a demonstration in canning 
at the Botanic Garden on July 27. Modern methods of canning 
were taken up and demonstrated. The vegetables canned were 
raised in the garden of the Flatbush Garden League. This 
garden was started on our grounds by the League as a part of 
their short course in gardening given them at the Botanic Garden 
this spring. The demonstrator of canning, Miss Mary Barber, 
was sent by the New York Food Aid Committee. The demon- 
stration was open to the public and about fifty people attended.
