 trees two years planted, in alternate rows ^\■itll check rows between. 



June 4tli, applied to fifty pear trees, partly infested with scale. 

 Sijce of trees, one to four inches in diameter, witli check rows 

 between. 



July .jtli, all the trees were examined and the material was 

 fonnd in fairly sticky condition. No apparent harm to any tree,, 

 but the treated apples had fewer plant lice than the eheck rows. 



August 1st, the trees still showed no trace of injury, but the 

 banding had hardened sufficiently to make it desirable to retouch 

 with additional material. The treated pear trees shewed no differ- 

 ence in scale infestation as compared with the checks, but the 

 treated apple trees Lioked uniformly better, owing to the smaller 

 amount of plant lice infestation. 



October 1st, no injury showed on the treated trees, but the scaly 

 specimens were now so badly infested that active measures were 

 necessary, and they were sprayed very soon afterward with whale 

 oil soap stuls, at the rate of one pound in two gallons of water. 

 The "Tanglefoot" was retouched where it had hardened. 



November 1st, no treated tree of any kind showed injury or 

 benefit from the application. Mr. Pfeiffer states that he will con- 

 tinue the experiment another year. 



During the latter jtart of the season !Mr. Dickerson saw the 

 treated trees of the Joseph II. Black & Son farms at Hightstown, 

 and determined that in some cases material injury had been 

 caused. He requested that the subjects be kept under observation 

 and report made later. 



October 5th, the following report was made : "The black walnut 

 that was broken by the wind continued to die down as far as the 

 mixture was applied. The mulberry does not seem to be affected 

 in any way. Sweet cherries do not seem to be affected. Paragon 

 chestnut shows an enlargement where the material was applied on 

 a yoinig tree. An American chestnut that was older does not show 

 much effect as yet. Peach trees show two separate effects ; one is 

 to soften the bark and change the color of it and on one tree it is 

 plainly destroying the bark. On a plum tree of a European 

 variety we find that it is having practically the same effect as on 

 the peach, and on a prune tree we find that the bark is made 

 brittle, and yet spongy-looking. A quince seems to have been 

 affected the same as the prune. A Japan walnut does not seem
