Titus visited these two localities under instructions to look care- 

 fully into the condition of the trees which had been treated with 

 this kerosene spray, and according- to his report no damag-e had 

 been done at either place to trees of any description, while the 

 effect on the scale was very satisfactory. 



January 6-9, 1902, about 700 trees belong-ing- to Dr. H. V. 

 Ferrell, of Carterville, mainly apple but some of them cherry and 

 pear, were treated with a 25 per cent, emulsion, and 130 trees, all 

 apple but one — which was a pear tree — were sprayed at the same 

 time on the place of Mr. J. W. Ghent. August 15, no injury from 

 spraying- could be detected in these orchards, which bore a crop of 

 apples equal to the average crop of un infested orchards in the 

 neig-hborhood. 



At Makanda 450 trees belong-ing- to S. Y. Dickinson, mainly 

 apple with a few cherry and plum, received the same kerosene 

 treatment December 11-28, 1901. The apple orchard was on a 

 steep clay slope and appeared to have suffered considerably from 

 the drought of the preceding^ year, but there was no tang-ible evi- 

 dence Aug-. 16 of any injury due to the insecticide treatment applied. 



On the place of Lammer Brothers, about 225 apple- and pear- 

 trees were treated December 31 with a 25 per cent, emulsion, and 

 owing- to some apprehension of injury on the part of the owners 

 this place was very thoroug-hly examined by Mr. Titus August 16. 

 The trees were absolutely uninjured, as were also 530 apple-trees 

 belong-ing- to Mr. S. A. Carr, treated in the same way and exam- 

 ined at the same time. 



Indeed the only injury done to trees by kerosene during- the 

 winter of 1901-02 of which I have been able to learn, was that to 

 "peaches on the place of Mr. Henry Archer, near Beaming-ton, 

 Sang-amon county. A mixed orchard of 513 trees was sprayed 

 here November 29 to December 4 with a 23 per cent, emulsion of 

 kerosene. The orchard was variously composed of young- and old 

 trees, and included apple, pear, plum, peach, cherry and quince. 

 The young- trees sprayed — peach, cherry, and pear — were wholly 

 uninjured, but certain old peach-trees were, with few exceptions, 

 dead by July 12, when the place was inspected at my direction by 

 one of my nursery inspectors. Dr. W. C. Bag-ley. From his report 

 it appears that the young- orchard above mentioned had been cul- 

 tivated the preceding- year, but that the old orchard in which the 

 dead peach-trees stood had received but little care, not having- 

 been cultivated for several years, and that the trees of various 

 kinds remaining- in it, both those which had not been sprayed and 

 those which had survived the treatment, were in poor and un-
