the same type will produce seedlings of the best 
form and finish; blending sorts of different 
types will bring forth the most distinct kinds. 
In order to gain knowledge, it is well to prac- 
tise both these extremes, but the best suc- 
cess will probably follow where a mean course 
is pursued. 
This matter of cross fertilization of roses 
places before us a vast field in which to 
study and experiment; and although we have 
so little to be drawn from the past which 
may guide us, the fact of its being largely 
unexplored seems an attractive feature. We 
can experience sensations somewhat similar 
to those of the traveller who penetrates a 
new country, for though he may not be the 
first to make discoveries, he can be among 
the first to chronicle results and make the 
discoveries useful. It is still open for m- 
vestigators to learn and make known general 
principles, which should guide us in raising 
new roses. It will be a gratification for me 
to know that I have contributed, in some 
measure at least, to this result. 
As few readers are likely to be familiar 
with the mode of manual fecundation, I will

the reason that insects are not there trouble-
