not be sprayed at all and others were incompletely done. A general 

 record was made, especially as regards foliage conditions. 



October 30th, all the peach, apricot and nectarine trees were thor- 

 oughly sprayed with "Scalecide," one part to twenty parts of water. 



November 16th, all the trees were thoroughly sprayed with ''Scale- 

 cide," one part to twenty parts of water, and as a test of injury, cherry 

 and nut trees were sprayed as well as fruit trees. On the 30th most 

 of the apples and the quinces were yet in pretty fair foliage, but most 

 of the other trees were quite bare. 



Tree 1 — Mariana Plum. The tree ended the season of 1904 in bad 

 condition, with much dead wood and a bad coating of scale. Some of 

 the dead wood was cut out during the winter and some of the scaliest 

 branches were removed. 



March 6th, drenched with Textil Oil at the rate of one part to 

 twenty of water, and as the tree had had an application of "Kill-0- 

 Scale" in October, 1904, this made the second dose of petroleum for 

 the season. 



The tree had started April 13th, and blossoms were out on the 

 30th; but development was irregular, both in leaf and blossom, and 

 up to May 11th it was in bad shape. At that time I cut out con- 

 siderable wood from the inside, shaped up in general and gave the 

 tree a decent outward appearance. But the bloom was straggling; 

 there was almost no set, and not until May 35th was it in full foliage 

 and of a decent appearance. 



May 37th, sprayed to a drench from the northwest side with 

 soluble petroleum, one to thirty, to test the effect on foliage, and on 

 the 30th noted that no apparent harai had been done. 



As the season advanced the condition of the tree improved steadily, 

 and on the examinations during June and July no scale breeding was 

 noticed. Two fruits matured August 3d, freedom from scale con- 

 tinued during the month, and on September 13th the record was : 

 "Practically no scale. The tree is freer now than it has ever been at 

 this season." On October 1st the record was: "There are some 

 scales; but they must be sought, and at first view the tree seems 

 clean." 



October 34th, was yet in full, healthy foliage and looked better than 

 it had for two years past. No dead wood ; no coated twigs or branches. 

 Sprayed from the southwest with "Scalecide," one lo twenty, and 

 covered as completely as possible by quartering, in a high wind.
