has been seen at other places, but no publicity had been given to 
the matter. 
I have also information — received May 29 — from near Pock- 
lington, Yorks., with specimens accompanying, showing presence 
of this same attack. In this case the moths were noticed flying 
about in large numbers on a plot of about five acres of cab- 
bages which were just nicely above ground. Of course, the re- 
appeai’ance of the pest is most unsatisfactory ; but, though no 
doubt it was very injurious in many places last year, still it did not 
cause anything like the amount of mischief that was feared, and 
from the very early date of observation now (whilst it is still open 
to remedial measures, instead of being sheltered beneath the spread- 
ing leafage), it is to be hoped that we may keep it in check. 
Amongst dry dressings which were reported last year as service- 
able, remedially, the following were more especially noticed : — A mix- 
ture of 10 cwt. of soot, 8 cwt. of nitrate of soda, and 1 cwt. of sulphate

of ammonia, mixed well, and sown broadcast by hand while the dew 
was on the leaves, at the rate of 1 cwt. per acre. The application 
of dry dressings should in all cases be made when the foliage is 
damp, in order that the powder may adhere. 
Nitrate of soda and salt — about 4 stone per acre of each sown 
by hand along the drills — have also been found useful, and so has a 
mixture of three-quarters soot and one-quarter lime sown on the 
plants. 
I do not find mention of “ Fisher Hobbs mixture ” (which is an 
excellent deterrent for turnip-flea beetle) being tried, but I should 
consider that in the present early stage of the attacked plants it 
would be very likely to be of service. This consists of 1 bushel of 
quicklime, 1 bushel of gas lime, 10 lb. of soot, and 6 lb. of sulphur, 
pounded up together very fine, and distributed when the dew is on. 
The above is enough for two acres of young turnips. 
Nitrate of soda, it is unnecessary to say, is very useful, by
