The Harvard University Graduate School of Landscape Archi- 
tecture is offering this summer a six weeks' course on Trees and 
Shrubs. The course will include lectures and special reading; iden- 
tification in class-room and field excursion. It begins on July 2nd 
and continues until August nth, under the instruction of Mr. Ham- 
blin. 
The Lake Forest School of Landscape Gardening, under Mr. 
Ralph Rodney Root of the University of Illinois, is also being con- 
tinued this summer. The attendance is smaller than last year, 
owing to the war, but excellent work is being done by the students. 
The Audubon Society is making a special plea for the song birds, 
which, owing to the high cost of meats, are being killed by the thou- 
sands for food. It is doubly important this year when bumper crops 
are imperative, that these birds should be saved. They are our 
insurance against the ravages of insects. If you can help, write to 
the Society, 974 Broadway, New York, and offer your assistance. 
Miss Willmott has sent a few more perennial seeds from England. 
The sale of these helps her to support a colony of Belgians on her 
estates at Great Warley. The supply this time is very limited, so 
write to Mrs. Henry at once if you wish some.
