argillacious loam must be more frequently 

 turned than a light, calcarious mould. 



The olive-yard should be manured at least 

 once in three or four years; but it would be 

 more beneficial to sustain its strength by 

 moderate annual supplies. Most species of 

 manure , while they increase the produce of 

 the Olive, impair the quality of its fruit; 

 the finest oil is made from wild trees grow- 

 ing in calcarious lands of moderate fertility. 

 Vegetable substances are preferable to ani- 

 mal manures for fruit trees in general, and 

 especially for the Olive and the Vine. When 

 animal manure is employed, it should be 

 tempered with marl, sea-weed, leaves, etc., 

 and applied only when the whole is reduced 

 to mould. To soils deficient in this ingre- 

 dient, calcarious matter is of the utmost 

 utility, and great benefit is said to be found 

 in Spain from sea-water poured upon the 

 roots of the Olive. 1 But the finest manure is 

 the offals of the fruit that has been pressed ,

 Seminario de la Cultura a los Parrocos , by Don Anto- 

 nio Melon , an enlightened Spanish ecclesiastic.
