THE farmer’s manual. 
n 
the dew is on, in the morning, especially sandy, or 
light loamy lands, (when ploughed in summer,) and 
even in moist weather, if the season is dry ; but as a 
general rule, improve a dry time, both for your 
pliiughing, hoeing, and for your seed-time ; your crops 
will always repay your attention, some extraordina- 
ries in your soil excepted, and the surface will derive 
most benefit from the harrow in dry weather. 
Harrowing. 
No instrument of husbandry requires the judg*- 
meiit of the farmer more than the harrow : it is capa- 
ble of doing the most good, and hurt, at the same time, 
of anv other instrument. 
1. The harrow, in field husbandry, answers to the 
rake in Hardening, and cannot be made to pulverize 
your tillage lands too fine ; but if this is done after 
your seeds are sown, it will cover them often too deep, 
and thus injure your crop ; and in flax and hemp, of- 
ten double the labour and expense in pulling ; and 
in your grass seeds, by covering too deep, will destroy 
their growth. 
2. M ike it a general rule to level, and pulverize, 
as much as is necessary with the harrow, before you 
cast your seed, and then cover lightly with the har- 
row, according to the hardness, or stifluess of the soil 
— when the lands are light, once over will answer; 
but when they are stiff, twice may be necessary. 
Rolling. 
The field Roller is an instrument much used in 
Europe, and in some parts of our own cotintry ; and its 
good effects much extolled by the best writers, and 
upon the following principles; viz. 
1. When used U|ion sward ground broken up for 
corn, it compresses the furrows to the earth be- 
neath, and thus guards the corn against the effects of 
droughts, by equalizing moisture.
