the country where it is being carried on. Every 

 little rootlet should be preserved and the hole should 

 be of sufficient size to give the roots plenty of room. 



Irrigation 



In some sections it is necessary to irrigate the 

 young trees. If this is done by flowing the water 

 around them, do not fail to cultivate before a crust 

 forms. Water soaking into the earth makes a com- 

 plete system of pores, and evaporation is very great, 

 if these be not broken up, by thoroly pulverizing 

 the surface. Iff lowing water cannot be obtained, 

 tiling four inches in diameter and fifteen inches 

 long may be set, one piece near each tree, the top 

 being on a level with the surface. Fill these oc- 

 casionally by hauling water and cover to prevent 

 evaporation. 



A substitute for tiling may be made of pieces 

 of boards three and five inches wide, and of de- 

 sired length. These give an opening for water three 

 bv three inches in the clear.
