 distance 5 the original tree for want of nourishment, the soil

 cess, and that generally is effected by manure. When the 

 soil is congenial to plants the nutricious sap accumulates, 

 and the plant grows vigorously so long as there remains a

 as the one is dependent on the other. 



CUTTINGS, &C. 



This is an easy way of propagating the different varieties 

 of our fine and most beautiful species of plants that decorate 

 the parlor. There are different methods of striking cut- 

 tings, and different seasons that are more congenial for that
