3. Thirty concrete posts with connecting chains for festoon 
roses. 
The growth made by the roses surpassed our expectations and 
there was a fair display of rose blooms on the Tea and Hybrid 
Tea varieties as late as the end of November. Some of the climb- 
ing roses have made canes sixteen feet or more in length and prac- 
tically all of them have made vigorous growth. 
It may be desirable to record that it seemed necessary, in the 
attempt to control “ Black Spot ”’ and leaf-eating insects, to dust 
the roses with a sulphur-arsenate of lead preparation thirty-six 
times throughout the growing season. This averages about once 
in every five days. The control of aphides necessitated fifteen 
sprayings with contact insecticides. 
North Addition 
The soil in this area (between Mt. Prospect Reservoir and the 
Museum Building) of about four acres is gradually improving. 
A dressing of stable manure, and green manure crops of rye, 
hairy vetch, and buckwheat, were plowed under during 1928. A 
crop of rye was planted in the fall for turning under in the spring 
of 1929. 
Miscellaneous . 
Trenches for water and sewer connections for a bubbler drink- 
ing fountain were dug, a concrete base cast, and the pedestal set 
up in readiness for the plumber. 
About 700 square feet of tar macadam was laid over the Hills’ 
bridge and its approaches. 
start was made on levelling depressions in the lawns caused 
by subsidence of-the soil in places formerly occupied by trees and 
shrubs. This is a fairly large undertaking, but should be carried 
out on the score of improving the appearance of the lawns and of 
facilitating mowing. 
Seed and Plant Distribution 
In connection with the International Seed [exchange, 2,015 
packets of seeds of trees and shrubs were distributed to foreign 
and domestic botanic gardens, and to other institutions and in- 
dividuals in the spring of 1928.
