Protection Against Insects and Disease 



As in fire protection, the spread of dangerous in- 

 sect infestations and diseases requires the aid and 

 direction of the public. Both the National and State 

 ii<>\ ernments should participate and appropriate liber- 

 ally to check the depredations. 

 Forest Renewal 



The renewal of forests on lands not required for 

 ain-icnltnre and settlement is an essential feature of 

 <i national policy of forestry and an effective pro- 

 gram should be worked out in each State, backed by 

 appropriate legislation and efficient administration, 

 which will achieve this object on private as well as 

 on public property. As in the case of fire protection, 

 forest renewal on private lands requires the parti- 

 cipation and aid of the public. 



There are two problems of forest renewal; first, 

 the restocking of lands already cut over and now in 

 a condition of waste; and second, that of providing 

 for natural reproduction as the timber is cut. Where 

 there is still seed or seed-bearing trees on cut-over 

 lands, continued fire protection may in many cases 

 suffice for restocking. Where there is no chance for 

 natural reproduction, planting or sowing will be ::e- 

 c'/ssary. The public will have to take over a large 

 portion of these lands and restore them to productiv- 

 ity. In many other cases owners may be induced to 

 restock their waste lands as a business undertaking. 



Provision for forest renewal should be made at the 

 time of cutting. Sufficient restocking of the average 

 private tract can be accomplished by natural repro- 

 duction without resort to planting or other intensive
