CORN. 
Oct. 21st. Mr. D. D. Gibb, replying from Thorn’s Farm, Lyming- 
ton, Hants, gave some information well worth considering regarding 
effects of manures, as well as regarding kinds of Wheat. He noted, as 
his experience of Hessian Fly attack on the farm :— 
“Barley may be termed the chief sufferer: in two. Wheat-fields 
adjoining Barley affected I failed to find proof of Hessian Fly, but did 
of sawfly. These varieties of Wheat were stiff-strawed, viz., Ambrose’s 
‘ Stand-up White’ and Webb’s ‘ Square-head Bed.’ The ground was 
well-manured also, top-dressed in spring with salt and nitrate of soda. 
This Wheat was after Clover-lea, second growth fed off with fatting 
sheep, afterwards receiving say about fifteen tons farmyard manure. 
One field sown with ‘ Webb’s Challenge White Wheat’ not after Clover, 
but getting quite as much (say twenty tons) farmyard manure,—did 
not get the top-dressing: this looked well and healthy, so far as my 
observation went, all winter and spring, but suffered severely from 
attack of Hessian and sawflies. The ground was a poor sandy loam 
lying close to the edge of the Solent, and the season was altogether too 
dry for it to produce a crop. Barley top-dressed in a similar way, and 
with kainite, superphosphate, and sulphate of ammonia, showed less 
sign of attack than where not top-dressed. I was therefore led to the 
conclusion that whatever manure causes vigour of growth and gives 
stiffness to the straw lends the plant strength to better withstand an 
attack, except in very bad cases, and when mixed with weed-seeds. 
“ Some stubble which could not be burnt at the time was carried 
into a yard and well trodden-in by fatting steers. I also have suggested 
the addition to this of gas-lime, which will at the same time render 
the mixture more pungent, and increase the manurial value.” 
Oct. 24th. Mr. W. Gillespie, in reply, added to previous information 
from Atlielstaneford, Drem, N.B.:—“ My Wheat was in no way 
damaged ; the variety ‘ Square-head.’ ” 
Oct. 26th. Mr. A. J. Whitcher, writing from Peckworth Manor, 
Stamford, said:—“ I have not noticed any Hessian Fly in the Wheats; 
variety grown, ‘ Square-head White Chaff.” Some fields of Barley have 
been greatly damaged. I found the later-sown Barleys much more 
heavily attacked by Hessian Fly than the earlier-sown. I also found 
that Barley grown on land that was Barley the previous year was very 
much more attacked than the Barleys grown after Turnips and Clover.” 
Oct. 27th. Mr. John Hardwick, Agent to Sir John Thorold, of 
Syston Park, Grantham, wrote in reply :—“ The usual kinds of Wheat 
sown in this district are the ‘ Square-head’ and the ‘White Chaff Bed,’ 
but more particularly the latter; and have not heard of any case where 
they have been attacked by Hessian Fly. The Barley-crop has been 
attacked, but not to any appreciable extent, about here.”
