Total of these estimated items 17,228l.

This, of course, is a mere estimate of the principal sources of
income upon which Mr. Jonas depends for a satisfactory result of his
balance-sheet. Each item is probably within the mark. I have put
down the crop of wheat of 750 acres at the average of thirty bushels
per acre, and at 6s. per bushel, which are quite moderate figures.
I have assumed 375 acres each for barley and oats, estimating the
former at forty bushels per acre, and the latter at fifty; then
reserving half of the two crops for feeding and fatting the live
stock; also all the beans, peas, and roots for the same purpose. If
the estimate is too high on some items, the products sold, and not
enumerated in the foregoing list, such as cole and other seeds, will
rectify, perhaps, the differences, and make the general result
presented closely approximate to the real fact.

As there is probably no other farm in Great Britain of the same size
so well calculated to test the best agricultural science and economy
of the day as the great occupation of Mr. Jonas, and as I am anxious
to convey to American farmers a well-developed idea of what that
science and economy are achieving in this country, I will dwell upon
a few other facts connected with this establishment. The whole
space of 3,000 acres is literally under cultivation, or in a sense
which we in New England do not generally give to that term--that is,
there is not, I believe, a single acre of permanent meadow in the
whole territory. All the vast amount of hay consumed, and all the
pasture grasses have virtually to be grown like grain. There is so
much ploughing and sowing involved in the production of these grass
crops, that they are called "seeds." Thus, by this four-course
system, every field passes almost annually under a different
cropping, and is mowed two or three times in ten years. This fact,
in itself, will not only suggest the immense amount of labor
applied, but also the quality and condition of 3,000 acres of land
that can be surfaced to the scythe in this manner.

The _seeds_ or grasses sown by Mr. Jonas for pasturage and hay are
chiefly white and red clover and trefoil. His rule of seeding is
the following:--

Wheat, from 8 to 10 pecks per acre
Barley, from 12 to 14 " " "
Oats, from 18 to 22 " " "
Winter Beans, 8 " " "
Red Clover, 20 lbs " "
