Tlic Mclatc was transferred frc^iri the Rdse Garden to a more 

 a])])ropriate location in the Rock Garden. 



The (jardcn \\-as dusted thirty times against hiack s])ot and 

 leaf-eating insects; and sprayed twice to control sucking insects. 



Medicinal and Citltnary Garden 



A more interesting kn'out of the culinary garden was achieved 

 hy revising the original plan and installing two knots with pat- 

 terns dating l^ack to Elizaliethan times. At the same time more 

 room was made for the growth of culinar}- hcrhs. 



Pests 



The first Japanese heetles of the season a])])eared on June 13 

 — ahout ten days earlier than usual — and enormous numhers were 

 seen during the first two weeks in July. The excessive rains in 

 July (16 rainy days. 8 of which were in succession — 17th to 24th), 

 however, lessened (heir activities and the damage was not so severe 

 as we feared it im'ght he. 



liven with aid froiu the weather it was necessary to spray 

 heavil}-. and more than 4,000 gallons of deterrents were a])plied. 

 Ho])ing that it might he i)ossil)le to secure protection \\ith rela- 

 tively non-poisonous materials we used 1,100 gallons of aluminum 

 sulphate and lime, and 400 gallons of tetramethyl thiuram disul- 

 jihide. The first named was not verv efifective — ])artly hecausc it 

 did not stick well during rainy jjcriods. Good results were oh- 

 tained with the tetramctlnl thTuram disul])hide mixture. Another 

 efi'ective hut jDoisonous sjiray material was lead arsenate with flour 

 added as a "sticker."' h'ifleen thousand ])oun(ls of a lO/f mix- 

 ture of leafl arsenate and sand was a])i)lie(l in the spring to 

 '* gruh-]M'0()t " 150,000 s(|uare feet of lawn. 



Scale insects necessitated the ai^plication of 1,200 gallons of 

 dormant spray (miscihle oil); and aphids, etc., required 1,200 

 gallons of nicotine-soa]) solution to kecj) them uuder control. 



Wild rahhits, Avhich are still uesting in the (jarden, continue to 

 cause much damage, ddie ])rol)]em of controlling them under city 

 conditions does not seem to have heen soK'ed.
