THE PLUM HOUSE. 51 
can then be used for show Balsams for seed. The 
cordon Plums, of course, always remain stationary, but 
with all the air that it is possible to give them, with 
frequent syringings. No aphides must be allowed on 
them, but no syringing should be done after the fruit 
begins to show. The constant pinching back of the 
young growth throughout the summer must be done, 
and the same to the pot-Plums, with a daily watering, 
and once a week some liquid manure should be given 
them till the fruit is fully grown, when it may be 
discontinued. 
Now, in a business way, suppose 120 Balsams are 
seeded in this house from the time the Plums are 
removed till November, the time they should be re- 
placed in the house again, at the rate of 2s. worth of 
seed per plant that would be 12/. in full. Thus it may 
be seen that a fair living for a small family can be 
realised from this one house. But let the reader bear 
in mind that it is easier to calculate these figures than 
it is to realise the amount. 
Let no one, moreover, suppose for a moment that 
nothing more is to be done than to get the trees and 
to place them in the house. Some degree of care and 
trouble is required, including attention to the watering, 
ventilation, syringing, smoking to kill the aphides &c., 
a careful lifting of the cordons and replanting them 
annually while they are young, the constant nipping 
out of the points of the summer growth, and top- 
dressing of the pots with a weekly watering of liquid 
manure during the summer growth, are things not to 
be omitted. Also ventilation during the growth and 
flowering in the spring and a daily syringing before 
the blossom opens—not while it is fully expanded, but
