thought proper: these are sometimes formed in the manner of a 
common detached bark pit, without any upright glasses in front, 
having a wall all around, five or six feet high behind, gradually 
sloping at each end to about four feet in front, and with only sliding 
glasses at top, more pai'ticularly the nursery stove, commonly and 
simply called the pit, because the whole internal space in length 
and width is often allotted entirely as a pit for a bark bed without 
any walk within, or door for entrance, the necessary culture being 
performed by sliding open the glasses at top, and the flues for the 
fires being formed in the upper part of the back wall above the 
surface height of the bark bed: however, it may be more eligible 
to form the succession stove particularly, nearly like the main one, 
with erect glasses in front and sloping sashes at top, with a door for 
entrance, and an alley or walk nest the back wall at least, or more 
eligible if continued all round the bark pit. 
Observing, however, if these smaller stoves are joined to the end 
of the main one, they may be divided from it only by a sliding glass 
partition for communication with each other, particularly the suc- 
cession and main stove, but with separate furnaces and flues to each 
department, because the young pine plants do not at all times 
require the same degree of fire-heat as the older pines, especially 
those of proper size for fruiting, so that by having separate tires, 
the heat can be regulated accordingly. 
The nursery stove or pit maybe of smaller dimensions in respect 
to width and height than the succession house, if thought con- 
venient; and if designed wholly as a pit without any path or walk 
within, six or seven feet width may be sufficient, by five or six high 
in the back wall, and four in front, the whole internal space being 
filled with tan three feet deep to form the bark bed, serving chiefly 
as a nursery in which to strike and nurse the annual increase of 
crowns and suckers of the ananas orpine plants the first year; also 
to raise many tender plants from seeds, cuttings, &c., without in- 
cumbering the main stove; and when they are forwarded to such a 
state of growth as to require more room, they are removed to the 
succession house. 
But the succession house may be nearly on the plan of the main 
stove, though of smaller dimensions both in the width and height, 
and is intended to receive the year old pine plants from the pit or 
nursery stove. In order to plunge them at greater distances, suf- 
ficient to give the whole proper scope to take their full growth 
another year, when they will generally be arrived to a proper size 
for fruiting the year following, being previously removed in autumn 
to the main fruiting stove to succeed the old fruiting plants, 
which generally by September have all yielded their produce, are 
then removed away and their place supplied by a sufficient quan- 
tity of large plants from the succession house, being arrived to 
a proper state of growth to produce fruit next summer; the 
largest succession house is at the same time replenished with 
the plants from the nursery pit, which next autumn will probably 
be also arrived to a proper size for removing to the fruiting house 
to succeed the others, and the nursery-pit supplied with young
