CORN. 
from presence of Hessian Fly attack. Mr. Mills forwarded me the 
portion of the stalk, with the puparium or “flax-seed” still adhering, 
for my inspection. 
This is one of the instances in which it would be of much interest 
to know what occurs next year, following on this very slight appear¬ 
ance observed, as, in reply to further inquiry, Mr. Mills wrote me, on 
Nov. 2nd, that he had examined a great quantity of Wheat, and on a 
great many farms, but could not find any appearance of attack except 
in this one case. 
August 12tli. A sample of Hessian Fly attack on Barley-straw 
was sent by Mr. E. Whitfield from Goring Heath (Oxon), near Beading, 
with a note that he feared he had discovered the presence of the pest 
in two fields of Barley. “ I had not noticed it during the growth of 
the corn, for, owing to the long drought and the Corn Sawfly, it had 
looked bad,—short in the straw and thin on the ground ; but to-day, 
when placing it in the barn, I was struck by the peculiar appearance 
of some of the stems, and on examination soon found the ‘ flax¬ 
seeds.’ ” 
August 12th. Specimens of Hessian Fly puparia (one “flax-seed” 
down near the root) were sent me from Glanmore Cottage, Stony 
Stratford, by Mr. J. Stebbing, with the note that they were found on 
Wheat in that neighbourhood. The Wheat-stems on which they were 
found were fallen,, and the corn prematurely ripened. “ In all cases 
the attack of the insect is made near the root of the plant.” 
August 12th. Mr. W. Formby forwarded specimens of Hessian 
Fly infested Wheat-straw from The Cottage, Morningthorpe, Long 
Stratton, Norfolk, with the information that there were many more in 
his field. 
August 18th. Mr. John Norwood wrote from Balby Bourne, 
Lincolnshire, forwarding stalks of Barley containing what proved to 
be “ flax-seeds” of Hessian Fly for examination, and the observation 
that if this was the case, “ this district is very badly infected indeed. 
For the last week I have found it in every field of Wheat and Barley 
on the farms under my management, extending to about 900 acres, 
belonging to Lord Aveland. In the twenty-acre field of Barley, from 
which the specimens sent were obtained, they may be picked up at 
every step. Several of the fields are sown with clovers and grasses 
amongst the corn ; therefore it will not be possible to follow the course 
recommended, viz., to plough in the stubble, &c. I have found 
similarly affected stems in several fields on adjoining farms, and I fear, 
from the large quantities found, some of which are near the third knot, 
and will be carried away in the straw, that it will be impossible to 
contend against them.”
