On White Mustard. 
XVI — On White Mustard. — By George Jksty. 
I BEG to offer my second leport on the growth of white mustard 
fur feed or for manure, in doing which I do not mean to exaggerate 
or misguide any person on the subject, but give a fair and im- 
partial opinion that there is no plant more palatable for sheep, 
and of so quick growth. When ploughed in, from the quantity of 
vegetable matter decomposed in the soil, it cannot fail to afford 
food to almost every plant. 
The land in wliich I ploughed it in last autumn was part of a 
field having failed twice for turnips; the other part was boned 
and ashed, and produced a good crop of turnips, which were fed 
off and folded by sheep in the usual way. The mustard land had 
no bone or turnip, or any other manure, but wholly manured by 
the mustard being ploughed in. Ju<t before the wheat was fit to 
cut my neighbovu's inspected the whole field, and were of opinion, 
as well as myself, that the mustard part was quite equal to the 
other both in straw and in corn. 
This last summer I sowed at different times a considerable 
breadth — first, the latter end of May, which came up cheerfully, 
but being on a high, dry soil, the weather took the same effect 
on it as it did on the turnips in general ; however, a third part of the 
plants remained, which made very strong growth, and I fed it off 
by sheep. On the 6th of July I again sowed, after tares had been 
fed off ; there was still that obstruction, by the unfavourable weather, 
for the growth of vegetables. Notwithstanding 1 had in that case 
a very good crop, which I also fed off with my sheep: they did 
remarkably well on the feed. I likewise had a thin piece of rape, 
in which I sowed 7 ibs. of mustard per acre the middle of Augvist, 
which made very rapid growth, and filled up an excellent piece of 
feed, as high as the hurdles, which was fed off about Michaelmas, 
and since sown to wheat — in all cases I find it perfectly whole- 
some for sheep. In this neighbourhood there has been one instance 
where a good crop of oats was cut and carried the latter end of 
July, and sown to inustard inmiediately, which produced a very 
luxuriant crop, and fed off by sheep in October. I have had many 
inquiries on the subject of sowing white mustard for feed since 
my publication, from almost every county in England. The result 
has proved very satisfactory, in confirmation of which I beg to 
offer to your notice a communication I have just received from 
Mr. Hale, of Horndean, Hants : (by tlie writer's authority you 
may publish his letter,) which is very similar to many others I 
have been favovu-ed with, too numerous to submit to your notice. 
As there have been doubts e.Kprcssed of eradicating the mustard 
from strong soils, I beg to say the wliite seed will not remain in
