15. Flower Gardens 
The miscellaneous flower gardens already established at 
conservatory range I, along the paths leading to this 
range from the elevated railway station and in front of the 
border screens along the New York Central and Harlem 
River Railroad, have all been maintained with minor 
modifications, and the plants labeled for educational pur- 
poses. It is proposed to modify these plantations by sub- 
stituting for the border screen garden between the Bedford 
Park Boulevard entrance and the Mosholu Parkway 
entrance a large collection of dahlias, some of which have 
been grown in the nurseries and others have been offered 
by dahlia experts. It is also proposed to modify the plan- 
tations at conservatory range 1 by growing the various 
plants in somewhat larger groups than they are at present, 
not by reducing the number of kinds exhibited, but by 
bringing plants of the same kind together. Some of this 
work may be accomplished in the spring. 
16. Nurseries and Experimental Grounds 
The area occupied by these plantations near the pro- 
pagating houses has not been materially modified. Ex- 
perimental work in plant breeding has been carried on here 
by the Director of the Laboratories, assisted by six ad- 
vanced students in plant genetics, and practically all pre- 
pared land was utilized. Dr. O. S. Morgan, Professor of 
Agriculture in Columbia University, continued his experi- 
mental work on Indian corn on an area of about one- 
quarter of an acre. Many plants were moved from the 
nurseries to the various labeled collections during the spring 
and autumn. The nursery work would be facilitated by 
the construction of about I,o0o feet of narrow stone road. 
17. Conservatory Range I 
The grouping of the collections in the great public green- 
house has not been changed; additions have been made 
nearly throughout the series, and some duplicates have been
