The distance suitable for fruit trees and plants in commercial plan- 

 tations varies considerably in different regions. The more important 

 factors in determining the proper distance for any given species are 

 the fertility of the soil, the supply of soil moisture, the habit of growth 

 and relative vigor of the varieties, and the necessity of providing suffi- 

 cient space for operating -spraying machinery in combating insects and 

 fungi. Observation of local practice affords the safest guide in doubt- 

 ful cases.
