July 2. There are few living young on trees 33, 34, in and 112, and 

 apparently none on trees 35 and 13. 



Aug. 3. A few living young are found on trees 33 and 34 and none 

 on trees 35, 111-113. 



Sep. 7. Living young are rather abundant on trees 33-35, and none 

 are found on trees 111-13. 



Leggetfs anchor brand, 2 pounds to the gallon. Six trees were treated 

 with this insecticide. The conditions and time were the same as in the 

 preceding experiments, with the exception of tree 89, as noted below. 

 Tree 72, a Flemish beauty pear 9 feet high, was exceedingly infested 

 with the San Jose scale. Tree 73, a Howell pear 12 feet high, was very 

 badly infested, and tree 74, a beurre bosc pear 13 feet high, was but 

 moderately infested. Trees 89-91, old Mixon peach trees 10, 12 and 

 15 feet high respectively, were all badly infested with the scale. There 

 was not enough of the insecticide to spray the whole of tree 89, and a 

 part of it was treated with Good's whale oil soap no. 3. 



Ap. 19. Trees 72-74 and 89-91 are nearly white with the insecticide 

 and appear much drier than those treated with Good's soap. 



May 11. Tree 72 is dead, evidently on account of the extreme in- 

 festation with the San Jose scale. Old scales are peeling from tree 73, 

 which is still rather white with the soap. Tree 74 is also white with the 

 insecticide. The blossoms of trees 89-91 are opening and the young 

 leaves are appearing. 



May 14. The blossoms are open and very abundant on trees 73 and 

 74 and the leaves are pretty well out. The blossoms and leaves are 

 abundant and starting on trees 89-91. 



July 2. Living young scales are numerous on tree 73, and there are 

 apparently none on tree 74. Very few living young are found on trees 

 89 and 90, and a considerable number on tree 91. 



July 16. Trees 72-74 and 89-91 were sprayed with Good's whale 

 oil soap no. 3, 1 pound to 5 gallons. The day was warm, practically 

 clear and with a breeze most of the time. 



Aug. 3. Living young scale insects are hardly abundant on tree 73, 

 and there are few or none on tree 74. There are but few living young 

 on trees 89-91. 



Sep. 7. Living young are rather abundant on tree 73, and there 

 are but few on tree 74. Living young are extremely abundant on tree 

 89, and very abundant on trees 90 and 91.
