FOREST RESERVES PURCHASED

sure, open tank and brush. They are efficient in the 

 order named. 



The pressure treatment in large closed cylinders gives 

 thorough impregnation of the wood, which protects all 

 portions and makes the preservative less liable to loss 

 by evaporation in leeching. 



The open tank treatment consists of immersing the 

 timber in open tanks containing the preservatives, and 

 by the application of alternate hot and cold baths. Pene- 

 tration to a considerable depth is obtained. 



The brush treatment is superficial, but liberal coatings 

 of hot creosote or similar coal tar derivatives protect the 

 wood from decay to an extent which fully justifies this 

 form of treatment. 



The cost is naturally determined by the amount of 

 preservatives used, hence the pressure treatment is 

 adopted for crossties and structural timbers, where per- 

 manence rather than initial cost is the determining 

 factor. Choice between the open tank and the brush 

 treatments may be determined on the same basis or by 

 the availability of plants where the more thorough treat- 

 ment can be given. 



The application of preservative methods to industrial 

 needs and the requirements of the home builder will be 

 discussed in more detail in later issues. The railroads 



have already demonstrated the economy of using treated 

 crossties, bridge timbers and other structural material. 

 In sea waters infested by the teredo, creosoted piling 

 has prevented destruction of timber from marine borers." 

 On the streets of our larger cities creosoted wood block 

 has been found to be the most satisfactory pavement, 

 and the same materials are now being used for factory 

 floors. It is principally among the small consumers of 

 lumber and on the farms that the advantages of treated 

 material has not been realized. 



Fence posts, floor beams, planking and many other 

 kinds of timber used around every home could be 

 profitably treated against decay. An educational cam- 

 paign which is intended to extend widely the knowledge 

 as to the possibilities and advantages of treated timber 

 is under way. 



Essential facts and items of interest will be stated 

 on this page from month to month and at any time 

 detailed information may be obtained upon request from 

 the United States Department of Agriculture, the Amer- 

 ican Wood Preservers' Association, or the National 

 Lumber Manufacturers' Association. Inquiries may be 

 made direct to these organizations or through the editor 

 of the American Forestry Magazine. 



Forest Reserves Purchased 



THE purchase by the Government of 97,888 acres 

 of non-agricultural land in the White Mountains 

 of New Hampshire and the Southern Appa- 

 lachians has been approved by the National Forest 

 Reservation Commission, bringing the total area so far 

 approved for national forests in the East up to more 

 than 1,275,000 acres. This latest acquisition will involve 

 an expenditure of $380,000, or about $3.88 an acre. 



The largest parcel is in the Boone purchase area in 

 North Carolina, a block of 36,38G acres, which the owners 

 have agreed to sell for $1.90 per acre. The next largest 

 is in New Hampshire, a group of tracts comprising 23,- 

 518 acres, one of which will close a gap between the 

 tracts already acquired in that region, the price being 

 $7.21 per acre. The rest of the purchase is distributed 

 as follows: 



Nine thousand, seven hundred and twenty-three acres 

 at $4.96 per acre, in the Monongahela area, West 

 Virginia. 



Three thousand and sixty-two acres at $3.1(i per acre, 

 in the Potomac area, Virginia and West \'irginia. 



Two hundred and sixty-four acres at $3.50 per acre. 

 in the Massanutten area, Virginia. 



One hundred and ninety-eight acres at $3.49 per acre 

 in the Shenandoah area. Virginia and West Virginia. 



Thirteen thousand, four hundred and twenty-three 

 acres at $2.77 per acre in the Natural Bridge area, Vir- 

 ginia. 



Seven thousand, six hundred and ninety-four acres 

 at $2.89 per acre in the White Top area, Tennessee and 

 Virginia. 



Six hundred and twenty-six acres at $5.55 per acre in 

 the Savannah area. North Carolina. 



One thousand, six hundred and fifty-one acres at $7.28 

 per acre in the Nantahala area, North Carolina. 



Three hundred and thirty acres at $4.67 per acre in 

 the Cherokee area, Tennessee, and 



One thousand and sixteen acres at $5.33 per acre in 

 the Georgia area, Georgia. 



The lands have been examined and appraised by the 

 Forest Service and sales contracts will be concluded with 

 the owners by the Secretary of Agriculture as soon as 

 possible. They will then have to be surveyed and their 

 titles approved by the Attorney General before their 

 development can be commenced as national forests for 

 the use of the public. Practically all of the land is moun- 

 tainous, non-agricultural, and valuable only for forests. 

 Much of it has been culled or cut-over, but several large 

 tracts are comparatively heavily timbered. 



About half a million dollars now remains available of 

 the money which Congress appropriated for carrying out 

 the Commission's plan to acquire ultimately about 5,600,- 

 000 acres for watershed protection, timber conservation, 

 recreation, and the other uses made practicable by the 

 establishment of national forests in the White Mountains 

 and the Southern Appalachians.
