of the Executive Committee of the Children’s Science Fair, the 
Garden prepared a model exhibit for the Fair, which was held at 
the American Museum of Natural History, December 3 to 9, 
under the auspices of the School Nature League and the American 
Institute. 
The model was designed to demonstrate conditions necessary 
for the healthy growth and development of green plants. Since 
the primary object of the exhibit was to illustrate what school 
children could do themselves in this field, the experiments were 
made as simple, and at the same time as instructive, as possible. 
Mustard was used mainly for the material, for the reason that since
