propagating material. Tive lessons on “ Lilacs in Flower” were 
given. A new feature was culture and propagation, taken up at 
the last meeting by Mr. Montague Free. Cuttings of selected 
varieties were rooted, and in September distributed to class mem- 
bers. 
In the fall five lessons were given on the late flowering her- 
haceous plants; the last lesson, by Mr. Free, was on methods of 
propagation and division of roots. A generous quantity of roots 
of various species was distributed to members of the class. 
Mr. Charles I*. Doney, Assistant in Woody Plants, gave a course 
of ten lessons on Or namental Shrubs in the spring. 
In order to make these courses available to various groups I 
think it is desirable that they be given alternate years in the fore- 
noon and in the afternoon. 
SEED EXCHANGE AND ACCESSIONS 
During the year seeds were collected as usual for the Interna- 
tional Seed Exchange, and printer’s copy was prepared for the 
annual Seed Exchange List. In exchange for 1,797 packets sent 
to our foreign exchanges, we received 1,422 packets of seeds of 
woody and herbaceous plants for the plantations and conserva- 
tories. Also 140 packets were accessioned by collection and by 
eg1ft, and 377 packets were supplied to Botanic Garden members.
