Finally Dr Fernow applied his figures to the United States, 

 and pointed out that now the Federal government was giving aid 

 to reclamation schemes, good roads, waterways, etc., it would 

 not be out of the way to include reforestation in this list. 



In 1970, by which time the most advanced of the forests 

 planted now would begin to mature, Dr Fernow estimated that 

 the population of the United States would have become 

 225,000,000, and assuming that the per capita use of timber 

 had decreased to that of England, 14 cub. feet per year, this 

 would require the cut of close upon 1,000,000 acres per year of 

 first-class forest, growing for 60 years at the rate of 400 

 feet B M per year. To keep up a continuous supply 60 million 

 acres must be in that producing condition, The probability was 

 that not less than 100 million acres would be required to 

 satisfy all needs for wood material. 



Since less than ^^4 per acre would be required for planting 

 and interest account, an annual loan of ;^4, 000,000 for sixty 

 years — two dreadnoughts a year — would be ample provision. 

 Dr Fernow's concluding summary of his plan was as follows : — 



1. Each state to ascertain its quota of planting area, classified 

 for systematic procedure in its recovery. 



2. A co-operative financial arrangement by which municipal- 

 ities may secure the credit of the State, and States the credit of 

 the Federal government, for the purpose of acquiring and recover- 

 ing their quota. 



3. State planting to be done on a large scale, 



" If I have not developed a very definite and adequate plan to 

 meet our need for wood and timber in the future, I hope I have 

 at least opened up a line of thought which may tend to its 

 formulation."
