successful. It is known that the sap in a grow- 

 ing tree exerts considerable pressure while the 

 roots are absorbing Avater. When a. tree is set 

 out or transplanted, all the root hairs which ab- 

 sorb moisture are destroyed and new root-hairs 

 must be thrown out before the root-pressure can 

 be re-established. 



The method of supplying this pressure tem- 

 porarily is to place a can or bottle as high or 

 higher than the tipper limbs of a tree and con- 

 nect it by a pipe or tube to the end of one of the 

 freshly-cut-oflF roots at the bottom of the tree. If 

 a pipe is used, connection between the pipe and 

 the root is made with a small piece of soft rub- 

 ber tubing which can be made tight so it will not 

 leak. The can or bottle is filled with water and 

 connection made when the tree is planted. This 

 supplies both moisture and pressure, can be very 

 cheaply done, and we suggest that dry-farmers 

 who are planting trees under trying conditions 

 give it a trial. 



TEMFOBAB'S' Some protection from the wind should al- 



ways be provided. This may be done for each 

 tree by wrapping the trunk with paper or setting 

 a board on the side from which the prevailing 

 wind comes. It often pays to provide shade for 

 the trunks of newly-planted trees, and this is 

 important in certain parts of the arid region. 

 Some shade should be set on the south and west
