An exhibition of plants and flowers was held June 6 and 7 in 
the museum building by The Horticultural Society of New York, 
in codperation with the Garden. Owing to the lateness of the 
season, and the consequent delay in the maturing of peonies and 
roses, which usually form the main part of the June show, the 
exhibition was smaller than that of last Hoan Mr. Havemeyer 
made an interesting exhibit of peonies. He also exhibited several 
unusual plants, among them Spiraea a and Lilium col- 
There were in addition other exhibits of peonies, and 
also of irises and of orchids, both plants and flowers. The Garden 
made a display of the flowers of herbaceous plants, including 
peonies, and of shrubs and trees.

at the Garden for two weeks during June. Dr. Hall has been 
in the East for the past six months, two months of which were 
spent at the Garden in the study of American Compositae.

agricultural botany at the Nebraska Agricultural Experiment 
Station, is spending two months of the summer on a scholarship
