benefit the fanners, increase industrial ac- 

 tivity and do more than anything else to in- 

 crease by many millions a year the state's 

 tourist trade. By reason of its purposes 

 and achievements the association merits the 

 support of all who love Wisconsin and 

 would guard her interests. 



PULPWOOD FROM WOODLOTS. 



With recent investigations indicating that 

 the pulp and paper industry of New York is 

 finding only half its supply of raw material 

 within the state, the foresters of the college 

 of agriculture at Ithaca point out that the 

 time is rapidly approaching when the farm 

 woodlot as a source of pulpwood may well 

 be considered. 



A careful estimate of the available sup- 

 plies on privately owned land within the 

 Adirondack region reveals only a sufficient 

 quantity to maintain the present cut for a 

 period of about fifteen years. This condi- 

 tion will make necessary certain changes 

 within the industry, all of which are of 

 more or less vital importance to a large 

 number of farm woodland owners in the 

 state. 



There is within the Catskill and south- 

 western counties a large stand of material 

 suitable for pulpwood which is now largely 

 unavailable because of freight rates. 



TURPENTINING DOES NOT HURT 

 LUMBER VALUE 



The operation of turpentining pine trees 

 does not lower the strength of the wood, 

 according to information obtained by the 

 Forest Products Laboratory of the Forest 

 Service, United States Department of Ag- 

 riculture. The crude turpentine, or oleo- 

 resin, is not drained from a reservoir in the 

 tree, but is produced by the living cells 

 in the sap wood at or near the spot where 

 the cut is made on the trunk. No turpen- 

 tine is produced by the heartwood because 

 all of its cells are dead. The heartwood 

 may be saturated in places with pitch, but 

 this does not readily flow out as does the 

 resin freshly formed in the sapwood. The 

 major part of the tree is not aflfected in any 

 way, and the loss due to death of trees or to 

 a reduction or degrading of lumber is very 

 small when the proper method of turpen- 

 tining is followed ; this loss is more than 

 offset by the additional revenue obtained 

 through turpentining. The greater part of 

 the wood that is chipped away would not 

 have become finished lumber, but would 

 have gone into slabs and edgings at the 

 sawmill. With proper treatment the tur- 

 pentined faces remain healthy, and the 

 wood underneath does not become saturated 

 with resin to any great extent. 



AMERICAN WOOD PRESERVERS' 

 ASSOCIATION. 



The Service Bureau of the American 

 Wood Preservers' Association has been es- 

 tablished to promote the use of wood prop- 

 erly treated to resist decay, marine borers, 

 and insect attack, thereby aiding in the con- 

 servation of the forest resources of the na- 

 tion by making one stick of timber do the 

 work of several. 



Headquarters are maintained which act 

 as a repository for reliable information on 

 the practice of and the results obtained from 

 the art of wood preservation. 



The value of wood for construction pur- 

 poses is fairly well understood but for per- 

 manent structures treatment with a stand- 

 ard preservative, such as cresote or zinc 

 chloride, is absolutely necessary. 



The policy of the SERVICE BUREAU 

 is to give the public reliable information on 

 the treatment of timber according to the 

 standards of the American Wood Preserv- 

 ers' Association and the use of treated 

 wood. 



Publicity will be given to facts relative to 

 treated wood from the standpoint of econo- 

 my and conservation through the public 

 press, trade and farm papers, and technical 

 journals.
