the furrow, the near Side may be Somewhat Shorter; and a Cham may be extended from the end ofthe cross bar to a part

of the Shalt near the horse's Shoulder. v"

In going from the farm vard to the field, the pin or guide M, must belifted on to the hook L, which will bear the coulters off the ground. And when going on rough roads, if the coulter-beam C C and the axis of the wheels are laShed to- gether by a rope or chain, it will prevent the coultersreceiving any ipJury, by coming Suddenly to the ground.

"The grain or Seed must be put in the upper boxes E E, an equal quantity in each box.

The cups or ladles upon the cylinders, are of four different Sizes, and are distinguished by the numbers 1, 2,3, 4.

No 1. ThesSmallest Size,(painted white) for lucerne, clover, cole, rape,'&c. and will 50w two pounds per acre. Also for turnips, and wil] 50w one pound per acre.'

No 2.(painted red) for wheat.

No 3.(painted green) for barley.

No 4.(painted yellow) tor beans, oats, pease, tares, Sc-

By raising or lowering the slides GG, a greater or less quantity of grain or Seed may be sown at pleasure.

. When the Slides G G are 45 low as they can be, the wheat cups painted red will 50w Sömething more than three pecks of wheat per acre; and more in proportion, the higher they are - raiSed, not exceeding one bushel and a half when raised as high as they can be, in rows at nine inches a-part.

The cups painted green, when the Slides are as low as tbey can be, will Sow one bushel of barley per acre; and more in proportion as the Slides are raised, not exceeding two bushels, in rows at nine imches a-part.:

The cups painted yellow, when the Slides are as low as they can be, will 50w almost two bushels of beans, oats, pease,&6. per acre, and more in proportion as tbey are raised.

Upon Soils well cultivated it is recommended not to 80Ww more than one bushel of wheat per acre.

Barley, from one vushel, to a bushel and a half per acre.

Beans, from two, to two bushels and a half per acre.

Pease, two bushels per acre.

Oats, two bushels and a half per acre.

Tares, two bushels and a half per acre.

"The idea of over stocking the drill with Seed, is very absurd; the crops wil! be materialiy injured by 50 doing..

[t is recommended to make experiments upon different soils by Sowing diflerent quautities of Seed, in order to ascertain the most approved quantity per ace.

Iflandis in a high state of cnltivation, it is hardly posSible'te 80% t00 littJe ged, provided the distribution 1s regular.)
