that it is impossible to discuss this subject to any length without going 

 into a great amount of detail. The following figures, however, will 

 convey some impression of the costs involved in a box factory in the 

 important box and shook manufacturing district of New England. At 

 this box shook factory cutting about 12,000,000 bd.-ft. of white pine 

 and spruce per year and employing about 120 men the following costs

 or live-sawed stock. The boxes were used for canned vegetables, cereals, 

 milk, paints and shoes, and a number of specifications were required to 

 suit the individual requirements. The minimum size was a box 15 in. in 

 length, 12 in. in width and 10 in. in depth, and the maximum size was 

 40 in. in length, 24 in. in width and 24 in. in depth. The average costs 

 for the years 1914 and 1918 are given to show the rapid rise in charges

SIZES AND SPECIFICATIONS 



As indicated above, there are so many different sizes and specifica-

 subject in any great detail. 



Since one of the principal use for boxes is for canned goods the follow- 

 ing standard specifications for canned goods boxes as adopted by the 

 United States Food Administration and the Quartermaster Corps at 

 Washington are given. These include the kinds of woods used, the
