pose to observe, that although the above 

 may appear to be an operation miHta- 

 ting against nature, yet it is not al-

 continually formed by the intervention 

 of bees, Sec. in orchards and gardens 

 where different varieties of fruits are 

 grown, hence the number of different ap- 

 ples produced when stocks and seedling 

 trees are suffered to bear fruit, and in 

 some instances, very valuable varieties by 

 this means have been produced. In mak- 

 ing this illustration, and taking a fruit 

 tree for our clue, we are under the ne- 

 cessity of looking to a considerable lapse 

 of time for the result of our experiments, 

 but to those who are in the practice of sav- 

 ing cabbage or turnip seeds for sale it is 

 known that they m.ust not grow any two 

 different sorts near to each other, lest by 

 such mixture the seeds so saved become
