ditto, a few feet of spline for ventilators, and -f-inch iron rod 
for the same ; a ladder o for stoke-hole, one door and thres¬ 
hold for potting-shed, Fig. 8 ; also, one door, partly glass, 
and threshold for Fig. 1, two stakes and two pieces of rough 
hoard for potting-hench m ; 70 feet of scantling, 2f by 3 
inches for spars to roof of Fig. 3; a few feet of pantile lath 
for ditto, and 100 pantiles; three well-glazed 2-inch lights 
for Fig. 2, which can be bought ready-made and seasoned of 
any of the hothouse builders, these being the only parts, 
excepting the door for Fig. 1, that require a first-rate joiner 
to execute; 100 feet box of glass of the exact size required 
can also be obtained without difficulty, and will leave 
plenty in hand for repairs. Anti-corrison paint, the best for 
out-door work, with directions for using, can also be bought 
with the glass, as well as a stone of putty, or the latter can 
be made by any labourer, but is better if made some time 
before using. A window of some kind, which will serve for 
lighting Figs. 3 and 4, must be provided. 
In constructing the back wall remember to turn an arch 
where the boiler is to be fixed, to prevent the necessity of 
weakening the structure by cutting away ; also, to see that 
at least one of the hot-water pipes has a saddle cast upon it, 
for supplying moisture to the atmosphere, f p, g, and the 
dotted lines, Fig. 4, indicate the position for the boiler, 
furnace, and ash-pit under the building. 
It will be convenient, in this place, to say a few words 
about the multiplication of plants from cuttings, for by that 
method nine-tenths of all the bedding plants grown are pro¬ 
pagated. By far the greater proportion of plants that are 
multiplied by cuttings require artificial heat. Nevertheless, 
cuttings of many tender plants may be struck in the open 
ground, or in pots and in frames, without heat, during summer, 
and in every case the mode of procedure is nearly the same. 
Very much of what we have to say will be applicable to 
summer propagation without artificial heat, though our busi¬ 
ness is more directly with the propagation of plants in spring 
by means of the heat of a tank or a hot-bed, because that 
system must be resorted to with many bedding plants, and 
requires more care than propagating in the open ground 
during summer. We must suppose the heat to be sufficient and 
constant. If from fermenting material, there should be a 
large body of it in a nicely-tempered state. There is nothing
