where shown that a collection of them can likewise be 
grown as a successional crop with advantage. But 
where it is made a special article, it is no doubt a 
good plan to devote a whole house to it, which, 
whether for show or seed-saving purposes, should be 
of a good construction as regards light, room, and 
air. 
Those who may grow Balsams, either for show pur- 
poses or for seed, will find that the above plan will be 
a good one, as well as cheap, to carry out. As it is an 
annual which can be grown to the greatest perfection 
from seed sown in March till September, no further 
security from the weather is required than a careful 
protection against winds, and the slightly cold nights, 
&e. The seed must first be sown in seed-pans, and 
set in a brisk heat till it is well up, and then it may 
be removed to a cold frame, or to the house, tiJl the 
seedlings have made from four to six leaves, when 
they may be at once potted off singly into three-inch 
pots and kept cool and well watered. 
As soon as these are filled with roots, shift them at 
once into eight- or nine-inch pots, and then keep them 
close till they have made a full foot of growth, keeping 
them well watered. Then admit all the air possible, 
to prevent them from drawing up too much, constantly 
supplying them with an abundance of water, and once 
a week give them a watering with some weak liquid 
manure. It is immaterial what this is, but never give 
it too strong. 
Warrantable double and single seed may be easily 
saved from the same plant; that is, the seed that will 
produce none but good double-flowering plants in the 
next generation may be saved from the main spike of
