much surprise. It has since been most successfully 

 practised by Mr. Mearns, Mr. Spencer, gardener to 

 the Marquis of Lansdown, at Bowood ; Mr. Elliott, 

 gardener at Rudding Park, near Gainsborough ; and 

 other eminent horticulturists, whose combined infor- 

 mation we will here arrange, previously observing, for 

 the sake of those who are inexperienced in pot cul- 

 ture, that the cultivation of vines under the " coiling 

 system," and of those established in pots, differs in 

 some respects worth notice. The " coiling" system 

 proceeds on the assumption that the buds on the 

 ripened cane are already formed for fruit, and that 

 they only await a development under favourable cir- 

 cumstances. With regard to those established in 

 pots, the difference is that they possess already a 

 good root, equivalent to the demands of the branches 

 the moment they are in action : the latter, therefore, 

 do not require precisely the same management as the 

 former. 



Now, it is obvious that until roots can be formed 

 by the coiled canes, any undue excitement in the at- 

 mosphere must be at the expense of the concentrated 

 energies of the cane above the soil ; at least, in our 

 ordinary atmospheres. This points at once to the 

 necessity of a bottom heat much in advance of the 

 atmosphere. This is found to be the case in practice, 

 and much of the success with coilers must ever de- 

 pend on this circumstance ; in fact, by taking care
