PROPAGATION. IOI 
boarded-in to secure bottom heat, and this I 
believe to be the best method. Some rose 
growers make no attempt at confining the 
pipes or flues, and produce excellent plants 
without resorting to bottom heat, but it isa 
slower process, and there is a greater per- 
centage of cuttings which fail to root. Ad- 
vocates of this system claim that they secure 
healthier, stronger plants in the end than 
they would by the use of bottom heat. 
There is no doubt that plants propagated in 
a closely confined house ina high tempera- 
ture are apt to turn out of weak constitution, 
but we believe the best results follow where 
plants are propagated in a bed at a tempera- 
ture of about 70 degrees, with the tempera- 
ture of the house a few degrees less. How- 
ever, these matters concern nurserymen and 
florists more than amateurs, for this class 
does not care to put in operation anything 
that requires much expense. When but few 
cuttings are desired they can be placed in 
pots and will take root in four or five weeks 
after insertion, grown in any ordinary con- 
servatory or greenhouse. After the cuttings 
have taken root they should be potted in pots 
not exceeding two and a half inches in diame- 
ter. Certain kinds of roses take root with- 
out difficulty, others are so stubborn that the
