The flowers of tlic Bartlett pear arc fully perfect; there is chance for 

 abundant self- and close-pollinations, yet these fail to pive a satisfactory 

 yield of fruit. Usually no fruit sets to such pollination but sometimes small, 

 irregular shaped, and poorly flavored fruits develop as shown at the rij^ht 

 above. When i)roperly interplanted so that compatible cross-pollinations 

 are provided, fine fruits as shown at the left may be had. The growing 

 of a solid block of the Bartlett pear, or of most other varieties as well, de- 

 creases the yield and tlie (piality of the fruit produced is poorer compared 

 with the yield when tlure is i)ro])er interplanting witli other varieties.
