len, and cannot, therefore, produce any fruit except 
when impregnated by others. 
Tam also convinced, from observation and theory, 
that one kind will never change to the other by offsets, 
the runner bearing the same relation to the plant pro- 
ducing it as a tree grown from a bud does to the tree 
from which it was taken. It may, then, be asked, How 
does it happen that there are pistillate and staminate 
plants of the same variety ? J answer, It is not the fact, 
unless they have sprung from seed, or the plants have 
been taken from the fields in a wild state. 
That pistillate plants are surer and better bearers 
than staminate plants, is, I think, generally true, (pro- 
vided, of course, that they are impregnated.) And it 
would seem reasonable to infer that when but one of 
the sexual organs is complete, the other will have 
more strength. Plants, therefore, that are perfect in 
both organs, require a higher state of cultivation. 
There is, however, a wide difference in the product- 
iveness of different kinds that are perfect in both 
organs, some being much more liable to blast than 
others. G. W. HUNTSMAN.
