a foot deep, with the soil loosened up in the bottom is generally 

 sufficient for forest planting in these Islands. Exceptional cases, 

 however, make it practical to use larger or smaller holes as con- 

 ditions vary. When the soil is free and can be easily dug with 

 the spade, even a smaller hole than the one mentioned would 

 be sufficient, but where the soil is hard and stiff and requires 

 a pick to loosen it up, it will pay to make a larger hole; even 

 two feet square and 18 to 20 inches deep is not too large in 

 such cases. 



In very dry districts it h advisable to leave a space around 

 the tree after it has been planted, a little lower than the sur- 

 rounding ground, so that the tree may have the benefit of what- 

 ever moisture may collect. In wet districts the soil around the 

 tree after it is planted should be left a little higher than the 

 surrounding ground, so that the water may run off and not re- 

 main stagnant around the tree. 



Planting. 



In planting out great care should be taken to prevent the 

 tender roots from being exposed to the air. A;? much soil as 

 possible ought to remain intact around the plant. 



A very general mistake in tree planting is to plant too deep. 

 It must be remembered that the best soil is generally on or 

 near the surface, and the tender roots of the young plant will 

 take more kindly to it than to the often sour and poor subsoil 

 to be found a little deeper. When digging the hole the best 

 soil should be put at one side and used around the roots of the 

 tree when planting. 



After planting, hoeing and cleaning away the grass and weeds 

 is necessary until the young trees get well above the grass or 

 brush. 



Forest trees like everything else will make a faster growth if 

 kept clean.
