The record is about on a par with that of the stronger solution 
of whale oil soap. The scale has been held in check in most 
instances, but there is no approach to exterminative work, 
‘such as is effected by the mechanical emulsions of crude. 
petroleum. There are comparatively few extenuating circum- 
‘stances, since only five trees in this large lot were abundantly 
infested with the scale in the fall of 1900, and, as this condition 
‘was due to recent development, the bark of these trees was hardly 
rough enough to insure much protection to the scales. 
Good’s whale oil soap no. 3, 2 pounds to the gallon. This solution 
was tried on 15 trees. They are as follows. Trees 12-14, 57-59 
and 98-100 are seckel pear; trees 31-33 and 76-78 are globe 
peach. Their condition about the close of the growing season, 
‘Sep. 7, 1900, was as follows. There were very few or no young 
‘scale aioe on trees 57 and 78, very few on trees 76, 77 and 98, 
few on trees 31, 99 and 100; they were rather abundant on trees 
8 and 59, abundant on trees 32 and oe and extremely abundant 
-on trees 12-14. 
May 22, tree 100 had set considerable fruit; trees 31, 32 and 
77 were injured somewhat by winterkilling, the tips of many of 
‘the smaller limbs being dead; tree 76 was also badly affected in 
‘this manner. 
July 6, there were very few or no young scale insects on trees 
31, 32, 57, 76, 77, 78, 98 and 100, few on trees 33, 59 and 99, and 
rather few on tree 58; they were rather abundant on tree 14, 
abundant on tree 12, and very abundant on tree 13. The bark 
‘of both trees 58 and 59 is quite rough. 
Aug. 9, there are very few or no young on trees 31, 32, 33, 57, 
76, 77, 78, 98 and 100, and few on tree 59; they were rather abun- 
‘dant on trees 13, 14, 58 and 99, and abundant on tree 12. | 
Sep. 25, there were few or no living scale insects on trees 57, 
‘98 and 100, few on trees 76 and 78; they were rather abundant 
on trees 31, 32, 33, 58, 59 and 99, abundant on trees 13, 14 and 
77, and very abundant on tree 12. 
The record given above is not very bright, particularly when. 
we remember that in this lot there were no very badly infested
