This is a process needed only on land that has not been under
cultivation long enough to become level. All new land has many knolls of
greater or less size. As soon as the roots are out sufficiently to allow
it, the knolls should be plowed and leveled with a common scraper. Most
farmers neglect it as injurious to the soil, and too expensive. But when
we consider that rough land never gets well plowed, and that the gradual
wearing away of the knolls will continue their unproductiveness for a
number of years, it will be seen that the cheapest way is to plow and
scrape the land level at once, and thoroughly manure the places from
which the soil has been scraped.
