CABBAGE. 
At first the plant appeared checked and stunted, and eventually the 
bulb went quite rotten. 
The land was a Wheat stubble, thoroughly well worked in autumn, 
and again in spring twice. Farm-yard manure (made principally 
from fatting beasts), at the rate of twelve to fourteen loads per acre, 
was ploughed in, and the seeds drilled immediately afterwards, on the 
flat, with burnt ashes mixed with Proctor’s Turnip Manure, at the 
rate of 3 cwt. the acre. 
The seed came up well, and the plants appeared perfectly healthy 
until after they were singled out, when they began to fail from the 
attack of a maggot which very much resembled a sheep maggot. 
The headlands of the field were not planted till nine or ten days 
after, and only burnt ashes and artificial manure were used ; these were 
perfectly healthy. 
In the bad attack of Cabbage maggot at Admaston, Eugely, which 
I am favoured with an account of by Mr. T. Carrington Smith, the 
spread of the mischief was checked by a soaking rain. This is well 
worth notice, as whatever effect the sudden wet had directly on the 
maggots themselves, it would so wash down the mineral super¬ 
phosphate and the nitrate of soda which had been given round the 
plants as to run on a vigorous growth past attack, and stop some of 
the coming attack also by closing up many crannies by which Cabbage 
Flies about could get down to lay at the Cabbage roots. 
On June 15th Mr. Carrington Smith forwarded specimens of Cow 
Cabbage plants and Cabbage Fly maggots, with the information they 
were collected from a growing crop, and that, if the progress of 
destruction continued at the rate it had been going on during the 
week, there would soon be many gaps in a most promising plot of 
nearly two acres. 
The plants had been procured early in April from Farnham, in 
Surrey, and got well established before the drought. The land on 
which they were planted had a good dressing of farm-yard manure, 
and 6 cwt. of mineral superphosphate in the ridge. There was also a 
sprinkling of (say) 2 cwt. of nitrate of soda per acre, distributed not 
all over the ground, but round the plants. Later in the year Mr. 
Carrington Smith mentioned that, shortly after the above communi¬ 
cation, there came a good soak of rain, which seemed quite to stop the 
spread of the maggots to any other Cabbages. 
The plants that were used for filling up the gaps did not seem to 
be attacked, although no local application was used ; but at the 
beginning of August If cwt. of nitrate of soda per acre was sown 
broadcast all over the plot of Cabbages which then covered the 
ground. 
There is doubt in this case whether the eggs from which the
