prominent citizen I was summoned by telegraph both by the fore- 

 man of the fumigating- squad and by the owner of the premises, 

 and experienced no small difficulty in re-establishing- cordial relations 

 between the parties concerned. To do a thoroug-h piece of work 

 some destruction of small shrubbery had been necessary, and the 

 leaves of several kinds of vines and shrubs were badly withered by 

 the g-as. 



An inspection made the following- year, April 14, 1900, showed 

 an unexpectedly favorable result. On one tree heavily coated with 

 scales many living- specimens were found under a crust of the dead, 

 but elsewhere two hours' search disclosed but three living- scales. 

 The place had been temporarily saved from serious damag-e by the 

 scale, but at a cost exceeding- the value of the rescued property, 

 and the failure to exterminate was evident. No attempt has since 

 been made by me to treat miscellaneous trees and shrubs on town 

 lots by the fumig-ation method. 



The trees and shrubbery on twenty-one lots in this town — all 

 on which the San Jose scale could be found — were sprayed with a 

 twenty per cent, soap emulsion of kerosene April 10-19, 1900. 



Orchard Fumigation at Sfarta. — A reg-ion of more than 

 twenty-five square miles about Sparta, in Randolph county, was 

 known by me to be g-enerally infested with the San Jose scale in 

 the fall of 1899, this and the neig-hborhood of Richview, in an 

 adjoining- county, being- the most important infested districts 

 discovered in Illinois up to that time. After the completion 

 of the the annual nursery inspection of 1899, preparations were 

 made for a g-eneral campaig-n with the fumig-ation equipment in 

 this neig-hborhood, and my party took the field at Sparta Octo- 

 ber 18 under the charg-e of Mr. E. C Green, with Mr. R. W. 

 Braucher as inspector. Here it continued actively at work for the 

 next two months, by which time it was evident that with the 

 appropriations available it was altog-ether impossible to treat the 

 infested premises of this reg-ion fully by the fumig-ation method, 

 and the party was transferred to Richview, in Washing-ton county, 

 for work on another plan. 



The Sparta district was mainly one of small farm orchards, of 

 which only here and there one had expanded in a way to make its 

 fruit an important part of the owner's crop. Many of the infest- 

 ed orchards were very old or contained some very old trees of a 

 size to make fumig-ation exceeding-ly difficult or to put it altog-ether 

 out of the question (Plate VII.). Taking: one orchard with 

 another, infested trees of every size were to be found, from those 

 recently set out to giant survivors of the planting-s of the early pio-
