spring. You cannot well get the land too firm.—(Joseph Addison, 
Mapledurwell, Basingstoke.) 
On the chalk at Mere Down, Wiltshire, it is noted that the 
Cambridge ring roller is the best remedy, the heavier the better, and 
that it should be passed over the same land two or three times.— 
(Thomas Henry Baker, Mere, Wilts.) 
I have tried rolling, both with and without salt, and salting 
without rolling, the two former with good effect, the latter apparently 
with none. This year being particularly favourable for rolling the 
Wheat crop, it was all well rolled in good time, and we have not 
suffered.—(A. H. Bowles, Clandon, Guildford.) 
I have suffered considerable loss by the ravages of the Wireworm 
in my Wheat plant on land where the previous crop was seeds, and 
the most convenient method for destroying them is to roll the ground, 
and make it like the turnpike road. The Wireworms come to the 
surface and the crows take them.—(Thomas Allen, Thurmaston, 
Leicester.) 
A field on my farm (on light soil, sea coast of Pembrokeshire), 
which has been under grass since 1878, was ploughed 2 ins. deep in the 
spring of this year. A second ploughing during April went to 4A ins. 
deep. No manure was applied, and it was sown with Barley. The 
Wireworms soon appeared, more especially in the bores, when a heavy 
CrosskilVs ribbed roller was used, first across the furrows, and after¬ 
wards along them. This had the desired effect, the Wireworm 
practically disappeared, and a good average crop of Barley followed. 
—(L. P. Williams, Penberry, St, David’s.) 
It is a general custom when crops of Barley or Oats are injured to 
use the Cambridge roller as soon as possible, which no doubt does good, 
as it kills some of the insects and helps to keep alive the plant which 
had been partially destroyed.—(Thos. Jones, Penpont Farm, Brecon.) 
I have found that compressing the soil before sowing the crop, and 
during the early growth of the plant, has to a limited extent prevented 
the Worm from working. Hoeing the crop is also good ; in short, 
any means of disturbing the Worms or hastening the growth of the 
plant, to enable it to get away from their attacks, is beneficial.— 
(Frederic Beard.) 
Mustard. 
Notes of the serviceableness of Mustard as a preventive for Wireworm; 
also instances of Wireworm not being observed as attacking various 
leguminous crops , as Clover , Peas , etc., if no grass ivas present, either 
as a part of the crop or as a weed amongst it. 
It has been found by practical experience that the growing and 
ploughing in of White Mustard will get rid of Wireworm. The use of
