Cultivation of Arable Land* Potatoes. Sets proper for. .97 



If, indeed, the ex pence in feed, where whole potatoes are made ufe of, be 

 taken into the account, it is probable that the large cuttings of middling fized po 

 tatoes, where only one or two eyes are preferved, may be the moft proper and 

 fuccefsful in producing crops ; as where whole potatoes are employed, from the 

 great number of eyes, and the confequent production of numerous ftcms, the crops 

 may be liable to be too thick or clofe on the ground, and in that way be rendered 

 weak, and the produce of courfe fmall and deficient, the bulbs not being able to 

 fwellout and diftend themfelves fufficiently. 



It is remarked by the ingenious experimenter mentioned above, that cr the great 

 er the number of ftrong fibres and roots, the more they fearch for food, and the 

 more earth they difplace in the courfe of their growing, which divides the foil more 

 minutely and gives it the advantage of better pulverifation ; and the greater abun 

 dance there is of leaf, the more nourimmeRt is extracted from the air, and which 

 are thus made to co-operate more with the vegetable pafture in the foil in bringing 

 the plants to perfection ; and the thick foliage of the crop, by its umbrageous 

 clofenefs, has the fame ameliorating qualities with a heavy crop of peas, or beans, in 

 deftroying weeds, retaining the dews, and preventing the drought from penetra 

 ting and exhaufting the foil.&quot;
