results. Tree 113 was in very full bloom, showing that the 

 fruit buds had suffered no injury. Tree 114 had a number of 

 open blossoms and many unfolding buds. The latter had been 

 seriously injured by the scale in earlier years and was recover- 

 ing very nicely [pi. 2]. Tree 47 had many blossoms on it, though 

 they were somewhat sparse, while 41 produced a very large 

 number. Tree 101 bore a considerable number of opening blos- 

 soms. Trees 17-19 showed a slight blistering on the smooth 

 bark, due probably to the application of crude petroleum, but, 

 so far as could be discovered, no appreciable injury had been 

 done. It should also be stated that the bloom of peachtrees in 

 general was not full, so that a scarcity on the sprayed trees was 

 not necessarily due to the insecticide used [pi. 5]. 



An examination June 12 showed that the petroleum was still 

 apparent on the trees, but signs of its presence were limited 

 very largely to a darker, more moist appearance of the bark. 

 There was very little or no odor of the oil in the orchard. 



An examination June 20 showed that tree 28 bore some living 

 females, and that young were found under the scales in small 

 numbers. Tree 73 was very badly infested with young scales 

 last spring, and these had been mostly destroyed. Living 

 females were found only on the underside of the branches, in 

 places where they were badly incrusted. The bark of this tree 

 had cracked to some extent, probably owing to the oil. Trees 

 23 and 60 had some living scales, and the bark of each was very 

 rough. Tree 103 was in excellent condition and had made a 

 very satisfactory growth, for in 1900 it was very badly infested, 

 and now the bark on the lower limbs and trunk is very rough. 

 Tree 101 has a poor shape, owing to the death of limbs, resulting 

 in all probability from the application of undiluted crude petro- 

 leum in 1900, but it is now making a fine growth. It has thrown 

 out many suckers, which is due probably to its previous hard 

 treatment. The bark of the lower limbs and trunk is very rough. 

 A detailed examination of these trees was made July 5 with 

 the following results. There were few or no young on the 

 following trees, 17, 19, 24, 20, 27, 34, 35, 42, 45, 46, 60, 62, 03, 

 64, 66, 70, 71, 74, 80, 81, 87, 88, 89, 90, 91, 101, 102, 103, 104, 109, 

 110, 111, 112, 113; there were few or very few young on the
