to push forward the growth of plants is, I believe, very beneficial ; 
it acted well for our turnips." — S. S. 
" Nitrate of soda and salt about four stones per acre of each, 
sown down by hand along the drills, was very effective in setting 
the plants growing, and a scuffler fitted with boughs was tried at 
Gorton and answered very well indeed ; as also did four to six 
gallons of parafi&n per acre applied with Strawsonizer. We should 
have tried soot and lime had not the ravages been stopped, should 
also have walked a flock of lambs backwards and forwards over the 
plants, which I believe would be very beneficial and would act as a 
J scuffler would, and not injure the turnips." — G. T. 
I " Only measure taken was heavy dressing with salt sown broad- 
cast, which did not appear to do any good." — F. W. 
" Where stimulating manure (nitrate of soda) has been applied 
swedes appear to have more vigour after severe attack has passed 
away ; not tried any spraying." — T. H. W. 
Summary. — In the foregoing observations it will be found that 
the remedies most appi'oved of as satisfactory are nitrate of soda, 
and use of scufHers, or of horse-hoes. Nitrate of soda, whether 
by itself or occasionally together with soot and salt, is repeatedly 
mentioned as having been beneficial. Salt alone is noted as having 
done no good, but the fertiliser far more named as beneficial than 
any other is nitrate of soda — and in some cases it is explained that 
the benefit is not from any known action on the infestation itself, 
but by keeping up the growth of the attacked plants. 
The use of the scufflers has also been found very serviceable, 
and on similar principles the horse-hoes have been found beneficial 
by passing them through the turnips with light boughs, or in one 
I case a net attached in front ; the caterpillars are so disturbed that 
many fall and many are destroyed, and the use of a plough with a 
' bunch of wheat straw, fastened so as to nweep tlie leaves before it, 
has also been useful. Other applications are slightly alluded to, but 
the above are what are chiefly reported as beneficial. 
3. Opinions as to benefit of heavy rains. 
" All the early-sown turnips attacked by these caterpillars ha% e 
undoubtedly much benefited by sudden and heavy rains. In one 
field at Thornham (Norfolk), on which the attack was bad, scarcely 
a living caterpillar could be found after two davs' heavy rains." — - 
E. A. A. 
" We were certainly fortunate at the time the attack was worst 
in having heavy rains." — A. B. 
" The heavy rains we have had have done more good than any- 
thing else. Even first showers after the attack began had a 
wonderful effect. My neighbours all concur in this opinion." — 
J. B. 
" Heavy rains marked the first symptoms of a stoppage of damage, 
but I think high winds and a lower temperature on the night of. 
July 22. and during the last four days of that month, were also of 
great benefit."— J. A. B.
