very little good result. Larvae were moving in great numbers, and it 

 was desired to determine whether a mixture of this strength had any 

 marked effect : — it had not. 



August 21st, applied a. kerosene and resin emulsion, from Mr. P. 

 Kamtz, to trees 8, 19, 20, 21 and 24, as recorded under the tree num- 

 bers. There was some difficulty in getting the solution, and next day 

 it appeared that a very uneven piece of work had been done and ma- 

 terial injury had been caused. The combination must be improved to 

 be of any use. 



August 22d, sprayed trees 15, 16, 23, 35, 42, 47 and 48 with arsen- 

 ate of lead, one pound in nine gallons of water. Except on trees 15 

 and 16, the application was chiefly to test the material which had loeen 

 made in Newark, for the Shade Tree Commission of that city, to 

 replace a lot that had been condemned as unsafe. No injury of any 

 kind developed on any tree and the material was reported as ac- 

 ceptable. 



August 26th, all the fruit was removed from all apple trees and 

 from the Vermont Beauty pears. The house was to be shut up for 

 three weeks, and to avoid raids the fruit was removed unripe. Only 

 the Japan Russet pears, quinces and Dwarf Duchesse pears remained. 



August 28th, all trees, save peach and nectarine, were sprayed with 

 arsenate of lead, one pound in twenty gallons of water, by Mr. Dicker- 

 son. The application was made to prevent injury from fall web- 

 worms, one nest of which appeared on tree 3 and other colonies of 

 which were indicated. The application proved effective. 



August 31st, sprayed with No. 3 emulsion, one to thirty, trees 19, 24 

 and 33. This is another of the kerosene and resin mixtures, which 

 worked very well in the pump and mixed almost perfectly. Results 

 are noted under tree headings. 



During September no general applications w^re made, and the 

 insecticides used were all on a small, tentative scale. October 1st, a 

 general examination was made to determine conditions and outline 

 later practice. On the 20th, trees 21 and 40 were cut out, the former 

 because it was crowded out, the latter because it was good for nothing. 



October 24th, started with the intention of spraying all the trees, 

 save cherry, walnut and chestnut, with "Scalecide," at the rate of one 

 to twenty; but though there was no wind in the early morning, it 

 arose when the work began and became so hi2:h that some trees could
