ovule is necessary to the enlargement of the surrounding 

 and supporting organs, it appears that very few observers 

 have endeavored to trace the influence of the pollen beyond 

 the seed, probably because the practical utility of the 

 operation, in most instances, ceases at this point, 

 although every observing horticulturist must have noticed 

 that the parts most valued in what we call fruits, are at 

 least dependent upon pollination, even if the act does not 

 extend to actual fertilization of the ovule. I use the 

 term pollination to designate an act in plants the equiva- 

 lent of co-habitation in animals, which does not neces- 

 sarily extend to or result in fertilization. The necessity 

 of the presence of pollen to produce perfect fruits and 

 seeds is not doubted, but the moot point connected with 

 this matter is, whether or not in cross-fertilization, the 

 pollen has any influence.!!! changing the form, color or 

 properties of the parts enclosing the ovary. My atten- 

 tion was first called to this matter some twenty-five years 

 ago, while experimenting with various pistillate varieties 

 of the Strawberry, the flowers of which, as is well known, 

 must be, fertilized with pollen from some perfect flow- 

 ered variety, in order to secure a crop of berries. When
