But, in fact, their Superiority arDse from the additional power given to the holder by the zv wheels; and?hat number 185 DOW used with the circular motion, by many good husbandmen.-- Vpon this principle a machine has been lately constructed, to 50w two drills at once 3 and where the one-bout ridges can be 50 exactly made as to be parellel to each other, in every part» it answers well.--Dhis drill has no wheels, its roller giving a circular motion, by means of a belt, to the axle upon which the two Seed boxes are füxt. It it drawn by one horse, and as two machines of the other forms, can easily be moved by the the Same power, It Saves nothing but the expence of a manz which, on Some lands, 15 much overbalanced by imperfect SOWING.

But the most Simple and cheap, and, I think, the most useful turnip drill in Northumberland, was invented a few years ago, by a most intelligent agriculturist, Mr. Bailey, of Chillingham, a gentleman who is also distinguished as an ab'e möchamcThis instrument. Has two wheels of about 26 inches in diameter, with an iron axle(of about the 5ame length) to which they are fastened. On the middle of this axle, is firmly fixed a Small cylinder about one inch long, and two inches in diameter, on the Surface of which are cut from ten to Sixteen cavities, of a SemiI-oval form, large enough to contain four' or five Seeds each. Upon. the axle 13 placed a wood hopper, or Seed box, which will hold about two quarts. This cylinder moves within a ho'lowed piece of brass fixt in the bottom of the hopper, into which hollowed part the Seeds Sink, and as it has an aperture at OnC end, three tenths of an inch long, and one tenth wide, it passes from thence into the Spout, or coulter, as the Semi-ovals(above mentioned) are brought, by the circular motion of the axle of the wheels, below this aperture.=-And as it has a Slip of iron Sunk into a groove in the back board of the hopper, which is Screwed down vpon, or raiszed from this aperture, the holder may augment or diminish the quantity of Seed, per acre, with great facility 3 the minimum quantity being 5own when the iron 78 SCrewed to the notch in the brass.---In general the plants after this machine do not grow s0 close and clustered 25 after most of those of a different construction, which expedites the hoeing.---With all of them the holder Should be particularly attentive in keeping the Seed dry, and in Separating all Stones, lumps,&c. from it, by a proper Sieve.

"[he cost of the Single drills is from 17. 65. 0d.to 31. O5. Od. 3 and that of the double machine from 4/. 108. Od. to 5/. 54. 0d. I am Sorry I cannot, at present, Send you drawings of them.
