 thickness, density and species and at the same distance 

 from the core. 



3. Even small deviations in the direction of the grain 

 of successive plies may introduce considerable warping of 

 a panel especially in the case of 3-ply constructions so 

 that it is imperative that the grain of successive plies be at 

 90 degrees. Considerable care should be exercised in 

 trimming veneer and subsequently gluing it so that this 

 rule be observed. 



4. Plywood panels made of low density veneer are 

 less inclined to warp than panels made of high density 

 veneer. 



5. in order to reduce warping of 3-ply panels, the use 

 of a relatively thick core and thin faces is preferable to 

 the use of plies that are all of the same thickness. A low 

 density core is preferable to one of high density. 



meet it. Merchants and consumers would, therefore, do well to 

 anticipate their requirements and take advantage of present op- 

 portunities of securing stock. 



Plywood is so useful and adaptable that only a shortage of it can 

 prevent its extended consumption, not only for those purposes for 

 which it has been used hitherto, but in many new directions. It is 

 being daily proved in all branches of the timber trade that the man 

 with stock on hand scores. The same thing does and will happen 

 in the plywood section. As factories get going the call will be for 

 immediate supplies, and it is necessary to be ready for it. 



Plywood Supplies in England 



A recent issue of Timber, London, contains the following relating 

 to the market for veneers in the British Isles: 



Moderate quantities of plywood have reached this country, and 

 further supplies are expected from various sources. While these 

 may suffice for the immediate demand, it is important to remember 

 that the consuming trades have not yet settled down to norma! work. 

 It is to be hoped, however, that when the final peace terms are 

 signed by the enemy, the numerous manufacturers will gain con- 

 fidence, and that special efforts will be made to get the industry 

 into a healthy swing. 



It cannot be doubted that the call for plywood will be very 

 great, but it is not so certain that the supply will be sufficient to 



Mahogany Auction Sales Reopened 



The London Timber News of June 7 says that the auction sales 

 of mahogany logs, which had been almost entirely suspended since 

 the outbreak of war, were resumed in the month of February, and 

 have been continued in each of the following months. Practically 

 all the wood for sale has consisted of logs imported by the Govern- 

 ment for war requirements, but liberated as a consequence of the 

 Armistice, in moderate quantities such as the market could absorb 

 without difficulty for ordinary commercial purposes. At the first 

 auction sale, held in London early in February, the prices realized 

 were about three times pre-war values; at the subsequent auctions, 

 both in Liverpool and London, prices came down to a basis of ap- 

 proximately double pre-war values, and there they have remained. 



At the end of March import restrictions were withdrawn, and 

 private shipments have since been arriving in moderate quantities 

 when freight facilities are available. The auction sales of May in- 

 cluded some shipments on private account, and others will be of- 

 fered at subsequent sales. Owing to the length of time the wood 

 has been awaiting shipment, the condition of much of it has greatly 

 deteriorated, and the prices realized for the quantity sold must be 

 regarded as high. The maintenance of these prices will be largely 

 governed by the extent to which shipments of similar character 

 are likely to arrive.
