large pots, we can discover numerous and important ad 

 vantages. It enables us to grow, in immediate proxi- 

 mity, vines of different degrees of vigor, which cannot 

 be so grown in a common border, where the roots min- 

 gle together, without injury to the weaker kinds. It 

 gives us an opportunity to water or to stimulate one 

 vine without affecting another, or to withhold water 

 from one without diminishing the growth of its neigh- 

 bor. It permits us to try experiments with different 

 fertilizing agents on single vines, and thus much may 

 be learned, by comparison, of the value of different fer- 

 tilizers, which cannot be done in a common border, 

 with the same ease and precision. In the divided bor- 

 der, we can take out and put in vines at pleasure, with- 

 out injury to the roots of other vines, and without 

 breaking up a large portion of the border. If any vine 

 proves too weak, or of a poor quality, we may remove it 

 at once, and replace it with another vine of a better 

 character, with the greatest ease, and the young vine so 

 introduced, having a section of the pit all to itself, will 

 receive no check from the roots of other vines. This is 

 an important advantage. There is no reason why we 

 should be so much hampered by the impossibility of 

 changing the stock of a vinery, without grafting, in- 

 arching, &c. By the plan here described, all this diffi- 

 culty is avoided, and we may change the vines in a 

 house, as easily as we change the stock in our pots ; re- 

 moving unprofitable vines, and substituting fresh ones, 

 well grown, from pots, ready for fruiting in a single
