 on the mother tree, until the parts which 

 are under the earth have formed roots fuf- 

 ficient to maintain themfelves, and then 

 they are to be feparated from the tree and 

 planted out. 



Thefe layers are more certain of growth 

 than cuttings, and do not require fuch 

 watering while they depend on the old 

 tree; but then this dependance makes them 

 lazy in putting put forth roots, with which 

 they often appear but moderately furnifli-

 the old tree : therefore it would not be

 tree, by nicking their branches half through, 

 and putting tar upon the cut ; this might
