PLANTING-TABLES. 121 



Third. Arranging the vegetables very nearly in the order in 

 which they should be planted or set out in the spring. This 

 would be nearly perfect, except in case of the cucumbers, if 

 the late cabbage were to follow the tomatoes. 



Fourth. Providing for easy rotation of crops by simply 

 reversing (with the exception of the permanent row of aspara- 

 gus and that of the parsnip and salsify) the plan. 



The number of rows of each vegetable, and the relative pro- 

 portion of each, may be varied, according to the wants of the 

 family, but the proportion given here will be found to suit most 

 families who depend upon the garden for both winter and sum- 

 mer vegetables. 



If necessary, the turning-ground at both ends may be filled 

 with winter squashes, as they are planted so late and at such 

 a distance apart that they would not seriously hinder the turn- 

 ing of a steady horse with a careful driver. 



7. Self-Fertile and Self-Sterile Fruits. 



Some varieties of fruits are more or less completely unable 

 to pollinate themselves, and they should be planted near other 

 varieties to ensure fruitfulness. Any variety will fertilize any 

 other variety of the same species, so far as known, if the bloom 

 occurs at the same time. In general, in planting a self-sterile 

 variety, every second or third row should be planted to some 

 other variety. The subject is little understood, but the follow- 

 ing lists represent the best of our knowledge.
