with yellow poplar and white pine for incubator cases and also for trays and 

 other inside work. Its stability, affinity for paint and durability are the 

 qualities desired for these uses. The bases and legs of incubators are of red 

 oak and sugar maple, probably selected for strength. Brooder case woods 

 are the same as for incubators except red oak instead of cypress went for 

 frames.

MUSICAL INSTRUMENTS. 



A few manufacturers of this class specialize in building finished piano cases, 

 and in the rough, which are called shells. Others make only the 

 actions and keys. Others not included in this study buy their cases of one 

 manufacturer, their actions of another, their sounding boards of a third, and 

 their hardware from those specializing in that line, and operate merely in 

 assembling the instrument and varnishing and finishing the exterior. 



Chestnut which combines sufficient strength with light weight and has a 

 special adaptability for holding glue is favored above all woods for backing 

 veneered cases, and in the quantity consumed leads all other woods reported 

 by the Pennsylvania piano makers and organ builders. It is entirely a 

 case wood for piano cases. That so much of the chestnut reported should 

 have been shiped from other states to the Pennsylvania piano makers is sur- 

 prising because the chestnut tree is common throughout Pennsylvania, and 

 in the production of chestnut lumber in 1912 Pennsylvania is among the 

 three leading states. Other woods used for veneer backing were red oak, 

 white pine, yellow poplar, and soft maple, because they possess qualities 

 of sufficient strength, are stable in holding their shape, are easily worked, 

 and have a special affinity for glue. The woods used for exterior finish 

 include red oak, white oak, and red gum, Circassian walnut, sweet birch.
