Killing Molds on Lumber by Steaming 



Molds thrive on the surface of wood when it is moist and warm. 

 In a dry kiln molds often develop on the surface of the lumber 

 to such an extent that they seriously obstruct the circulation of 

 air throuj^h the pile. This is such a decided hindrance to suc- 

 cessful kiln drying that steps must be taken to prevent the mold 

 growth. Various experiments have been made by the Forest 

 Products Laboratory to find a means of accomplishing this result 

 without injury to the lumber. 



The safest method found of stopping the growth of mold on 

 lumber in a kiln is to steam the stock at 170 or 180 degrees for 

 a period not exceeding an hour. This treatment heats the sur- 

 face of the stock sufficiently to kill the mold, and at the same time 

 the saturated air prevents too rapid surface drying, so that the 

 injurious efi"ects w^hich otherwise would be produced on the wood 

 by such high temperatures are avoided. 



Unless it is desired to relieve drying stresses at the same time. 



the interior of the stock should be heated as little as possible. 

 Therefore, the steam supply should be sufficient to reach the 

 desired temperature in 25 or 30 minutes. To accomplish this 

 result, plenty of live steam at a pressure of at least 70 pounds 

 gauge must be available. The size of supply line and the number 

 and size of perforations that may be required in the steam jet line 

 will vary with local conditions; it is impossible to make them 

 too large or too numerous, as the quicker the steam is supplied 

 the better the effect. 



Care should be taken to see that the stock cools in nearly 

 saturated air. Otherwise the surface will dry too rapidly, and 

 case-hardening difficulties will set in. 



How a Veneer Maker Sees Conditions 



The following is the manner in which present economic condi- 

 tions are sized up by the Chicago Veneer Company of Illinois, 

 which issues a monthly market letter over the signature of its 

 president, Benj. W. Lord. 



"When a very sick person passes the danger point, it is a 

 great relief although the patient is weak and must be watched with 

 extreme care and recovery is slow and tedious. This is the way 

 we feel about business conditions today. 



"The corner has been turned, the worst is over, but all business 

 must be watched and nursed very carefully. Recovery will be 

 very slouf and probably not noticeable until after October first. 

 Improvement will be gradual and we do not expect any boom or 

 big business for some time for the reason that the general public 

 has not the money to spend and there is so much unemployment 

 that the purchasing pow^er is greatly reduced. 



"There are still a number of sore spots that must be healed, but 

 even these seem to be improving and there is a general feeling of 

 confidence in the attention that has been and is being given to 

 business conditions in Washington." 



State Buys Veneer Company's Land 



Papers authorizing the purchase of 181 acres of land adjoining 

 Turkey Run State park, ow^ned by the Hoosier Veneer Company, 

 of Indianapolis. Ind., were signed a few days ago by Governor 

 McCray and members of the Senate finance committee and the 

 visiting committee. The additional tract will bring the acreage of 

 the state park to about 469 acres, the park being under the super- 

 vision of the state conservation department, of which Richard Lie- 

 ber is director. 



Condemnation proceedings for possession of the land in the 

 Parke Circuit court in 1920 were brought by the state and ap- 

 praisers were appointed by the court to fix the value of the land. 

 Under the agreement the state is to pay $9,733.40. or approxi- 

 mately $55 an acre. 



Allen Will Manufacture Disc Wheel 



C. B. .Allen, president of the Allen-Eaton Panel Company of 

 Memphis has secured a patent on an automobile disc wheel to be 

 made of laminated w^ood. He will manufacture the \\-heel in Mem- 

 phis, but is uncertain yet whether he will do this at the veneer and 

 panel plant of his company or will organize a separate company for 

 that purpose. Mr. Allen also had patented the glue which will be 

 used in manufacturing the new^ disc wheel. 



Progressive and Compartment Dry Kilns Compared 



All dry kilns now on the market are either progressive or com- 

 partment kilns. in the progressive type the drying conditions in- 

 crease in severity from one end of the kiln to the other, the material 

 being moved into severer conditions as it dries. In the compart- 

 ment type the same temperature and humidity prevail throughout 

 the kiln at any one time, beginning with mild conditions and in- 

 creasing in severity as the material becomes dry. 



The kiln-drying data and experience of the Forest Products 

 Laboratory indicate that each type has particular advantages on 

 certain points, as follows:
