Sir Thomas Beevor alſo, making a ſimilar experiment, found, 1. That fifteen potatoes, whole weight 3lb. 66 oOz. planted on fixty ſquare

feet of ground, produced ęſt. 10lb. 2. That fifteen of the ſame weight, alſo, planted on forty-five ſquare fœet, Produced 4ſt. 31b. 3. That ſeven potatoes and a half, cut into fifteen ſets, weight 11b. 11 Oz. planted on ſixty fquare ſeet, produced 3ſt. 5lb. 4. That ſeven and a half of the fame weight, cut into fifteen ſets, and planted on forty-five feet, produced zſt. r0lb.— „5. That fifteen potatoes, cut into forty-ſix ſets, and weighing 3lb. 602. planted on ninety-two feet, produced 1Oſt. IIb. 1, 2, and 5: One noted to be outſide rows; 3 and 4, inſide ones.(c) It is remarkable that the greateſt products were thé outſides. Mr. Whyn Baker, in Ireland, tried very ſmall ſeed, or ſets, on compariſon with reaſonably large; alſo with very large,

lb. oz. Reaſonably large, produce 84 3 Very fmall 5 64 12 19 7

—

This upon an acre would be a prodigious difference; but the difference between the reaſonably and very large, was little or nothing.(d) Mr. Williams, near Coventry, comparing hillocks at four feet; ſome with

three or four ſets, and others with one; the latter produced as much as the former(e)

OBSERVATION.

On the quantity planted per acre, authorities might have been greatly multiplied; but as it muſt depend much on the ſize of the cuttings, as well as on the manner of planting, it was thought better to confine them to a few leading points. A good deal has been done in this enquiry, but there remains much to do; for the queſtion of cuttings does not ſcem to be clearly decided by fufficient experiments, not to notice ſome ſtrong contradictions in thoſe experiments; which prove, that more trials are neceſſary to aſcer- tain the various queſtions that relate to cuttings.
