wild and cultivated, are absolutely devoia of pollen, 

 and cannotj therefore, produce any fruit except when 

 impregnated by others. 



I am 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 ? I 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 bat 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 produc- 

 tiveness of different kinds that are perfect in both 

 organs, some being much more liable to Uast than 

 others. G. W. Huntsman.
