considerably below the back walk; the compartment (n) is to tie the 
vines in during the time they are dormant, where by opening the 
front ventilators, they are exposed to the open air until the time in- 
tended for forcing ; the top (g) might do equally as well flat, the use 
of it being merely to prevent the heat finding access to the vines, and 
the cold entering the house, the two small holes (a, a) shew the return 
and termination of the flues, (a 4 & 5) in the back wall of the section. 
To Thomas Bland, j)age 186. — One reason why Mr. Lindley in his 
" Guide to the Orchard and Kitchen Garden" recommends one sort 
of grapes for vineries in the south and another in the north, may be 
that the ground being so much colder in the latter, he suspected the 
roots of the more tender kinds might suflfer by being planted in the 
vine borders out of doors. If this is not his reason we cannot tell 
why, we have found the sorts he mentions for vineries in the south, 
thrive equally well in the north. To a Constant Reader, page 127. 
The vegetable marrow is very easy of culture, requiring similar 
treatment to cucumbers grown on ridges ; it is scarcely worth growing 
requiring much ground which might be better occupied, we should 
rather recommend the advice given by Mr. George Harrison, p. 330. 
To "G. I. T." page 330; cuttings of Cucumbers and Melons we 
conceive cannot well be extended beyond the same season, they are 
taken off as soon as the seedling plants have produced sufficient young 
branches, and inserted in a pot filled with the same soil as that of the 
bed, they speedily take root, and are then planted in another frame 
for a successional crop, where they bear abundantly at an earlier age 
than seedlings. An article on the subject will appear early in the 
next volume. To a Subscriber p. 427 ; we cannot tell where Talc 
is to be purchased, neither have we ever yet seen it used, and are 
therefore unable to judge of its properties. Would any of our kind 
correspondents favour him with an answer ? To "M. D." p. 475. 
In the formation of a vine border, a successional produce is contem- 
plated, to continue for thirty, forty, or fifty years, without renova- 
tion except what may be received from top- dressings, the soil of 
those in pots may, for the most part, be renewed every year, the for- 
mer bears a profusion on fifteen or twenty feet of rod, the latter on 
four or five ; the former fill a situation with fruit, which could not be 
otherwise advantageously occupied, the latter stand in that part of 
the house which might be filled by pines, &c. requiring such situa- 
tions ; the flavour of grapes does not so much depend on the compo- 
sition they grow in, as on their judicious management in the house, 
although it must be allowed where vines grow on a wet bottom, no 
management will render them equal to those grown in diflerent cir-
