 kinds as possible and as few of the others, but it is necessary 

 to have some of the bi-sexual kinds near the pistillate kinds or

but it is probably about one to three or four, depending upon 

 the weather at the time of blossoming. It is safe to say that 

 when pistillate kinds are used, every third row should be of some 

 bi-sexual kind, selected so that it will be in flower at the same 

 time as the imperfect variety. The neglect. of this precaution 

 is a constantly recurring source of disappointment. Some grow- 

 ers recommend that every third plant in the row be of some bl-
