corresponds in Spain, as far as this culture is concerned, to one 

 degree further north. Olives do not grow well on granite soil. 

 The fruit produced on limestone formations is of the hest 

 quality. Gypsum promotes the growth of the tree. An 

 equable temperature serves hest ; thus exposure to prevailing 

 strong winds is to he avoided. The winter temperature should 

 not Ml below — 7° C. The quantity of oil in the fruit varies 

 from 10 to 20 per cent. ; sometimes it even exceeds the latter 

 proportion. In Provence at an average 24 lbs. of olive oil 

 are consumed by each individual of the population annually in 

 Andalusia about SOlbs. For obtaining the largest quantity of 

 oil the fruit must be completely ripe. Hand-picked olives 

 give the purest oil. Knocking the fruit from the branches 

 with sticks injures the tree and lessens its productiveness in 

 the next year. Spain alone produces about 250,000,000 lbs. of 

 olive oil a year.
