ffosa rugosa. The area in front of the south post at the 
Southern Boulevard entrance was planted with 15 plants of 
Rosa rugosa, to make it correspond with the other post. 
Along the driveways and paths 47 trees have been planted, 
including a row of 20 of the maiden-hair tree, placed between 
the west path and the driveway past the west end of the lakes. 
With the exception of those planted the past fall and a few not 
yet satisfactorily identified, all the recently planted trees along 
the driveways and paths have been furnished with stake show 
labels. There have been 185 of these placed in position the 
past year. 
Investigations 
Mr. Taylor and Mr. Eggleston have both acted as demon- 
strators in the courses of nature-study lectures given both in 
spring and fall. Mr. Taylor has been employed, in addition 
to his other duties, in working up the conservatory collec- 
tions, with the exception of the monocotyledons. He is 
gaining a knowledge of plant families and of cultivated 
plants and their literature which makes his services of in- 
creasing value. Mr. Eggleston has been engaged in work- 
ing up the herbaceous collections, and in work upon the 
genus Crataegus. 
In addition to the executive duties of my department, I 
have done much work upon the conservatory collections, 
confining myself in the main to the monocotyledons, espe- 
cially to the orchids and bromeliads, of which families many 
specimens have been brought in by Garden expeditions. 
That Mr. Eggleston might not be interrupted in his work 
on herbaceous plants, 1 assumed the immediate direction 
of the making of show labels for the fruticetum, the pine- 
tum, and for the trees along the roads and paths. I have 
also continued my studies upon the grasses of North America. 
Of the nature-study lectures given during the year, I deliv- 
ered three in the spring and five in the fall.
