HESSIAN FLY. 
26 
Farm Office, Woburn, Beds., specimens of Hessian Fly chrysalids, 
which he had that day found in a Barley field near. He mentioned that 
“considerable damage had been done to the crop, especially where it 
was late sown. Most of the pupge appear to be in the second joint from 
the ground”; and on August 12th Mr. Woodforde further mentioned 
that he had examined crops in several fields, and had no difficulty in 
finding chrysalids of the Hessian Fly, and, from what he could hear, 
the attack was very general. 
August 10th. Mr. W. Smith forwarded specimens from Marsh 
House, Quadring Eandyke, of puparia found on Wheat growing on 
land in his occupation in the parish of Quadring. 
On August 11th, Mr. E. Biley, late of Kipling Cote, Market 
Weigliton (who had previously been assisting me in investigations 
regarding Hessian Fly), writing from the Weir, Hessle, Hull, gave me 
the first information of the appearance of Hessian Fly in that neigh¬ 
bourhood :—“ I am sorry to tell you I have found Hessian Fly in two 
fields of Barley within a quarter of a mile of here, one of the fields in 
large quantities. It is about four miles from Hull and sixteen miles 
from Goole, but I cannot trace any manure as having come from Hull. 
I enclose a few specimens.” 
August 11th. The following note sent me by Mr. R. Stephenson, 
from Burwell, near Cambridge, remarks, as in a good many other 
instances, on the small amount of real injury caused by the attack :— 
“ Since writing you I have found ‘ flax-seeds ’ in three other fields of 
Barley, all one or two miles from each other, and from the field of 
infested Wheat. In one case the field is three miles from the nearest 
field known to be infested and in another parish, (Swaffham Prior). 
In all these cases the ‘ flax-seeds ’ are so few that the injury to the 
Barley is scarcely appreciable. I had to look closely to find any 
elbowed-down stems. I am thus inclined to think the Hessian Fly is 
distributed more widely than is generally supposed, and that in places 
such-as the above, where they are as yet few in number, they are not 
suspected, and so not searched for.” 
August 11 th, or a few days earlier, I had report, with specimens 
of Hessian Fly attack, from Mr. D. I). Gibb, of Thorn Farm, 
Lymington, Hants, and the remark :—“ I was struck with the fact, 
when first I observed the ‘ flax-seed,’ that in most cases it was 
shrunken and empty. Whether from inhabition of parasite or from 
the natural hatching of the fly, I could not form an opinion.” 
Bridgwater , August 11th. A single specimen of the “flax-seed” 
was forwarded from Shapwick, Bridgwater, by Mr. E. Mills, with the 
information that he had found it in a barton where a farmer was 
stacking his Wheat. He had examined a great many stalks afterwards, 
but could not find another. The crop did not show signs of injury
