half, or three quarters of a bushel, or if your land la 
poor, one bushel to the acre at this time ; it is a poor 
crop wh(;n considered in point of tillage, (unless roll- 
ed down and ploughed in as manure, as a fallow for 
winter grain,) or for the value of its grain; but it 
makes up one of the varieties of husbandry, will an- 
swer upon some poor soils, in place of some other 
crop, and may with safety precede any of the crops 
in a regular rotine, excepting Indian-corn ; this grain 
will not flourish after buck- wheat. 
No insect will injure your buck-wheat crop ; but 
your turnips are often exposed to the destructive fly, 
which frequently ruin the crop. To secure your tur- 
nip crop decidedly against the fly, steep your seed 12 
or 24 hours, before sowing, in fish, or train oil ; drain 
off the oil from the seed, and roll the seed in plaster ; 
this will separate the seed from the glutinous adhe- 
sion of the oil, render the casts free, and enrich your 
crop; all other steeps at times are said to fail; this 
is not only cheap and easy, but is said never to fail ; 
it will always preserve the crop. 
The value of turnips as feed, either upon the 
ground, or when pulled and housed, either for sheep, 
or cattle, I shall consider at large, under the article 
Stock, when the season for tillage is over, and the 
farmer has more leisure to read, and when his stock 
will necessarily claim his particular attention.

1 have said very little upon the cultivation of wheat 
by the use of compost, barn-yard, or other strong ma- 
nures ; they generally answer well upon a moderate 
soil, for one or two crops ; but when continued upon 
the same fields, or used upon a rich soil, the crops of 
wheat are generally ruined by the rust on the straw, 
(commonly called the blast.) Farmers are all full 
well acquainted with the fact ; but even the best wri- 
ters are not agreed as to the manner in which the rust 
is produced. They are generally agreed in this, that
