FORESTRY BRANCH BULLETIN No. 63 



In heavy machinery, birch, maple, and oak may be used more or less indis- 

 criminately for bases, rollers, and handles so far as the immediate result is 

 concerned, but taking into account the qualities of durability pertaining to 

 each species manufacturers use them according to the conditions to which the 

 machinery is exposed. Most of the spruce, native pine, Douglas fir, and hard 

 pine are used for saw-mill carriages and framework of saw-mill machinery. 

 Spruce is extensively used in grinding machines and boot and shoe machinery. 



In sewing-machines, birch, maple, gum wood, and oak are used for tables 

 made of solid wood or as a core under veneer for higher class machines. Tulip 

 is used a great deal as a core, but is also used for drawer bottoms. Birch is 

 the main Canadian wood for veneer core; maple is seldom used as such on account 

 of its tendency to warp. Red gum is used for drawers. 



A good deal of maple, oak, mahogany, and walnut is used as veneer in 

 the manufacture of sewing-machines. The greater proportion of the material 

 is purchased in the form of boards, planks, and dimension lumber of a superior 

 grade. The average price paid is given at $34 . 51 per thousand feet board measure, 

 which is a high average, only four industries paying more. 



The province of Quebec provides over 70 per cent of the raw material used. 

 Imports from the United States account for 26 per cent. The remainder is 

 chiefly supplied by Ontario. The Douglas fir is purchased from British 

 Columbia. 



TABLE 14 MUSICAL INSTRUMENTS. 



This industry comes thirteenth in the list demanding a yearly wood supply 

 of over 2,000,000 feet board measure, which forms 3 per cent of the total. 



Pianos and organs form the bulk of the product of the musical instrument 

 factories of Quebec. 



This industry uses thirteen kinds of wood, basswood leading and forming 

 one-quarter of the material reported. Spruce is specially used for air-pipes
