use of water. A wise adjustment and determination of tlie volume wliicli 

 can be safely taken from the tributaries of navigable streams for irrigation 

 without interfering with slack-water navigation should be presented to the 

 National Government as an urgent necessity. 



FOREST MANAGEMENT. 



(13) Both Federal and State aid should extend to forest preservation. 

 Practically all timber land should be withdrawn from sale, and timber should 

 be cut under regulation at fixed charges for stumpage. Revenue from the 

 sale of timber should be applied to betterments and extensions of the forest 

 areas and to the control and management of the forests. 



NATIONAL AID FOR PRIVATE LAND DISCOURAGED. 



(14) National aid in constructing storage works to be chiefly used for 



private lands should be discouraged, although cases might occur where 



reservoirs built to serve public lands would also be serviceable to adjacent 



lands in private ownership that had been once owned by the United States. 



In such cases the use of reservoired water for private lauds should not be 



prohibited. 



RECLAMATION OF PUBLIC LANDS. 



(15) Federal aid, for the present, should not be extended to actual 

 construction of works, except when the lands, or a large portion of the 

 lands, to be benefited belong to the public domain. The price at which 

 the land is sold should be increased by an amount sufficient to reimburse 

 the Government for its outlay; or the sale can be supplemented by a rate 

 charge or tax for a series of years such that ultimately the funds advanced 

 in the construction will, in the main at least, be returned to the National 

 Treasury. No works should be constructed unless the benefits conferred 

 will exceed the cost.
