 apart. 



The box- 

 making busi- 

 ness is carried 

 on in every 

 state, though 

 in Wyoming 

 n o statistics 

 are available 

 to show the 

 size of the in- 

 dustry. Fig-

 other states. 

 Two factors, 

 profoundly in-

 manufacture of 

 boxes in a re-

 and demand 

 for the boxes. 

 The latter is 

 the more im- 

 portant, for if 

 the demand is 

 strong, lum- 

 ber will be 

 brought in and 

 boxes will be 

 made. Illinois 

 affords a good 

 example of 

 this economic 

 tendency. The 

 state has little 

 timber of its 

 own, vet Illi- 



THE TUMBLING TEST FOR BOXES 



Makers and users of boxes wish to avoid risks of breakage in shipments and the attending losses and 

 delays. Consequently, they test the kinds of boxes they expect to -use to determine how much they will 

 stand. Above is a cut of a machine for giving the tumbling test. The apparatus was designed by the 

 Forest Service Laboratory at Madison, Wisconsin.

 other states, 

 except Vir- 

 ginia and New 

 York, in the

 of boxes, and 

 it brings 98 

 per cent of its 

 box lumber 

 from beyond

 Virginia a f-

 opposite con- 

 dition where 

 boxmaking is 

 influenced by 

 abundance and 

 cheapness of 

 timber. Vir-

 s h o o k s and 

 empty boxes 

 to manufactur- 

 ing centers 

 further north, 

 because cheap- 

 ness of timber 

 and favorable 

 freight rates 

 permit it. 

 N e v ertheless, 

 the orchards 

 and truck gar- 

 dens of Vir- 

 ginia are large 

 users of boxes 

 made in the 

 state. 



YOUR WALNUT WILL 



T^HE War Department authorizes the following state- 

 ment from the Bureau of Aircraft Production : 



More American walnut is needed for airplane propel- 

 lers and gunstocks. During the four years' test in the 

 present war this wood has proven to be the best mate- 

 rial for the manufacture of the above articles. 



The Government needs all the walnut that can be 

 secured during the continuance of the war, but it does 

 not buy the wood direct, as not all of it can be used for 

 the above purposes. Mills holding Government con- 

 tracts for gunstocks or propellers are anxious to pur- 

 chase walnut trees and logs, and the Government urges 

 the owners of trees or logs to sell them to the sawmills. 

 Owing to their inability to purchase sufficient walnut logs, 

 the sawmill proprietors have not been able to supply the

present requirements of this Government and the Allies. 

 And Every Tree Counts 



"Fight with your walnut trees," is the new slogan of 

 the Hardwood Section, Bureau of Aircraft Production, 

 and the Small Arms Section, Ordnance Department. Half 

 a dozen trees will provide lumber for a propeller and 

 supply gunstocks for a platoon of infantry. The lack 

 of one plane in the air or a platoon in the front line might 

 lose a battle. Every tree counts. 



If you have walnut trees 12 inches or more in diameter, 

 write to Capt. R. L. Oakley, Production Division, Small 

 Arms Section, Ordnance Department, Sixth and B 

 Streets, Washington, District of Columbia. He will 

 advise you where you can sell your walnut at a fair price.
