  There were plenty of Brown-tailed Moth's [brown-tail moth] nests but only a
very few were tenated [tenanted] so we cut them off only in this orchard
 tree and in the Berry Pasture. In the woods they did little
harm except near Bensen's Landing at Ball's Hill where they
threatened to strip the oaks which had to be sprayed. At least
90% of them must have perished during the winter, as some
suppose because of the extreme cold although Dr. Howard believes
that imported parasites were the chief cause of this destruction.
  Gypsy moth larvae began hatching on May 14 [May 14, 1914]. Few of them had
attained a greater length than 1/4 of an inch by the close of the
month when the oaks were in mostly full leaf & showing little
signs of injury. The larvai [larvae] were numerous enough in spots of 
limited extent and nowhere abundantly and generally dispersed,
at that date and were there dying by thousands of the "wilt"
although still so very small. Hence our spraying operations were
much less extended & expensive than usual costing in all perhaps $200
whereas last year & in 1912 I must have spent $1000 each year.
