such a depth that three inches only appear 

 above the surface. To encourage the forma- 

 tion of roots , the larger end , which is com- 

 mitted to the earth , should be smeared with 

 a composition of mould and animal manure, 

 and the end which is exposed to the air should 

 be protected by a covering of clay. Cuttings 

 of the roots, also, buried in an inclined po- 

 sition in trenches four inches deep, will 

 sprout in the course of the year; a few 

 months later the feebler stocks are plucked 

 up , and the more vigorous ones are left at 

 the distance of three feet. Another easy re- 

 source is found in the shoots that spring up 

 round the base of an old Olive, or from 

 roots laid bare and wounded for this pur- 

 pose. 1 



It is necessary, in every case , to ascertain 

 the point at which the original stock was 

 grafted. The offspring is invariably identical 

 in its nature with that part of the parent 

 tree from which it was separated; it requires 

 grafting, therefore , if it was detached from
