to actually hold it in so that it may not produce a subsequent 

 chemical action on the applied stain. As a result of this, the pores 

 of the sap section between the rosin rings are completely filled 

 with shellac so that the stain itself when applied is thus prevented 

 from properly uniting with the wood fiber, but must become merely 

 super-imposed artificial surface. In addition, the rosin of the 

 summer wood growth actually repels any applied shellac or stain 

 so that anything like even a color absorption is definitely im- 

 possible. Yet in spite of this, hundreds of thousands of feet ot 

 long leaf casing and base are being put into houses with exactly the 

 results mentioned and the inevitable adverse opinion which the 

 owner or tenant soon comes to form regarding Yellow Pine finish. 

 And every one of us knows exactly what happens to white enamel 

 on long leaf. It turns as yellow as cheese in a few years. 



Now short leaf, on the other hand, eliminates the factor of 

 rosin at the outset. If the stock is properly manufactured from 

 the sap section of the log, it will contain a negligible amount of 

 pitch. There is therefore, nothing to require neutralizing with 

 shellac and the stain or white lead is properly applied directly to 

 the raw wood. The color is thus permitted to penetrate the fiber 

 of the wood itself and as the grain is not hard, an even, uniform 

 absorption takes place, resulting in a pleasing, harmonious appear- 

 ance. Following the application of the color treatment, shellac and 

 varnishes are applied and rubbed down for a dull finish or the 

 varnish may be left in the gloss if desired. 



When applying white enamel, the same procedure obtains, that 

 is, the white lead priming is applied directly to the raw wood, 

 which permits of a complete engagement of the fiber and pig- 

 ment, known technically as chemical affinity. Thus an ideal base 

 for the enamel is established, which, when applied and rubbed to a Yellow Pine 

 mirror-like smoothness will successfully rival any finish or similar 

 treatment on any of the more expensive hardwoods heretofore 

 preferred by architects. 



In this connection, it was interesting to note first the in- 

 credulity and subsequent favorable opinion which many architects 

 manifested in the white enamel short leaf panels exhibited at 

 Cleveland. After seeing what really could be done on the wood, 

 which they were surprised td learn was a Yellow Pine different 

 in character from Georgia Pine, they were still further impressed 

 with the fact that it could be purchased at retail in Cleveland ter-
