138 Discussion of Industries 
ELEVATORS 
Under this head are included passenger and freight elevators 
and the necessary accompanying parts, such as guides, frames, 
gates, and platforms. The 1,288,000 feet credited to these 
uses is less than the actual quantity consumed, because a con- 
siderable amount of the material is the product of the planing 
mill and is hsted under that industry. In 1912 the pines 
contributed about 50 per cent of the total amount used, but 
this percentage is now much lower. Pitch pine which was 
reported in by far the largest amount in 1912 was not reported 
in 1919. Hard maple, which held third place in 1912, is the 
principal wood now used. ‘This species contributes nearly 
one-half of the total amount entering the elevator industry and 
is used principally for elevator floors, guides, and frames. 
Spruce stands next in amount consumed and has risen from 
ninth place in 1912 to second place in 1919. This wood also 
finds use as flooring and framing. Yellow pine occupies the 
third place of importance, being used to a large extent for 
guides and frames. Chestnut, hemlock, cypress, and elm are 
species listed which were not reported in 1912 and those 
reported in 1912 which do not appear in the accompanying 
table are pitch pine, red oak, silver maple, birch, and basswood. 
The total consumption of wood by the elevator industry is 
less than half that of 1912, while during the same period there 
has been only a small reduction in the number of establish- 
ments. It is probable that metal has displaced wood to a con- 
siderable extent in the industry, which may account for the 
decrease in wood consumption. There has been a considerable 
change in the order of importance of the different kinds of 
wood used since the last report in 1912. This is doubtless 
owing to the difficulty of securing suitable stock, at a period 
when manufacturers found it necessary to adapt to their needs 
the timber which they found available. The average price of 
raw material has increased from $31.06 to $79.93, which is a 
relatively greater increase than took place in many other indus- 
tries during the same period.
