In tropical, expecially dry situations, as 



Planting in East Africa, planting with naked root 



Yearlings is hardly ever practised. To avoid the 



with Ball drying of roots the plants are carried in 



baskets (banana fiber) and planted with a 



ball of earth. Another method, used with Pinus halepensis in 



Algeria, is to set the seedlings in petroleum cans filled with good 



soil and transplant them with a ball of earth. Or else the plants 



may be grown in loose (lath) or easily disintegrating packages, the 



plants being set with the package. 



This method has been suggested to be used on areas infested 

 by the Melolonta larva, and for specially difficult and exposed 

 situations.

In this article Doctor Thaler of Darmstadt 

 Pruning reports the results of inspecting the effects 



Rules of some pnming which was done fifteen 



years ago. After summing up the advan- 

 tages and disadvantages of pnming limbs in general certain 

 definite conclusions are reached in regard to methods. The cutting 

 should always be longest parallel to the axis of the tree and not 

 over 7 centimeters wide. The smoother the cut the quicker it 

 will heal over. Broadleaf trees heal quicker than softwoods. 

 With the latter a cut into the heartwood should always be tarred 

 if disease is to be prevented. Pruning can be most advantageously 

 done in November and December, should be confined to the lower
