HESSIAN FLY. 
23 
of Ancaster is seriously affected. I had only time to examine one 
field at Grantham, eight miles off, and found it there. All the crops 
that I have examined are so badly attacked that one minute suffices to 
find it.” 
After examination the same day at Horbling (also in Lincolnshire), 
Mr. Smith noted that he found “flax-seeds” in two fields in about 
half a minute’s examination. 
July 27th. Specimens of attack to Wheat and Barley were 
forwarded to me by Mr. William Priestley, Offord Darcy, Cambs., 
with the note that he had found them that morning in the border of 
Cambridgeshire, a few miles from St. Ives. 
On August 1st Mr. Priestley further reported :—“ Since writing to 
you last week respecting the Hessian Fly, I have carefully gone over 
several Wheat and Barley fields on my farm, and find puparia in a 
state more or less advanced; in some cases the fly has gone. To-day 
I have been into five other parishes in this neighbourhood. Every 
field I went into similarly affected.” 
July 27th. Mr. John E. Thurnall, Royston, forwarded specimens 
of Hessian Fly attack on fields at Great Chisliill, in Essex, about six 
miles from Royston. The fields infested, heavy land properly drained, 
and no foreign straw been used on the farm, which is 5-| miles from a 
station ; the land about 400 to 470 feet above sea-level, being nearly 
the highest part in the district. “ The chrysalis seems always to be 
just above the second joint of the Wheat, and I am sorry to say there 
are many fallen stems, but just above the second joint.” 
July 28th. Mr. E. H. Riddiford, Sutton, near Sandy, Beds., sent 
me specimens of Wheat-stalks infested with Hessian Fly. He had 
found it in two fields of Square-head and Browick Wheat: and on 
August 1st he further mentioned that since writing he had found 
“flax-seeds” in corn of two of his neighbours (Wheat and Barley), 
and heard of it being found at more than one locality in the immediate 
neighbourhood. 
July 28th. Mr. J. W. Poynter forwarded sample of Hessian Fly 
attack to his Wheat from Great Wackering, Southend, Essex.
