To come now to the enfuing work. The firft objedl of con- 
fideratlon is the Pine and Grape-flove ; and it muft be admit- 
ted, that the original and principal objedb of an Hot-houfe 
confifts in the culture of the Ananas or Pine-Apple; but ftill, 
if the Pinery be properly conflrudled. Vines may, at the fame 
time, be propagated therein to great advantage. 
I know there are are many perfons who dilTent from this 
mode of practice, and they found their opinions on the follow- 
ing objedtions : 
First, They fuppofe that Pine-ftoves are improper for 
Vines, becaufe the Pine being a tropical plant, it naturally 
requires a greater degree of heat than the Vine can polEbly 
bear. 
Secondly, Becaufe it is ufual to train the Vines along the 
underfides of the rafters which fupport the glafs-frames, they 
fuppofe that their leaves, by contributing to darken the ftovCa 
mufl, confequently, tend greatly to injure the crop of Pines. 
b 2 Thirdly, 
“ any where. A blade of grafs cannot fpring up, a drop of rain cannot fall, 
“ a ray of light cannot be emitted from the fun, nor a particle of fait be 
“ united, .with a never-failing fymmetry, to its fellow, without him ; Every 
“ fecondary caufe we difeover, is but a new proof of the neceffity we are 
“ under of ultimately recurring to him, as the primary caufe of every 
** thing.”
