The only complete data available on the consumption of wood for packages are total figures which include the material from which all three types are manufactured. A lumber consumption in 1912 of 4,550,000,000 board feet for shook and veneer boxes and fruit and vegetable packages is the most reliable figure available. It was compiled from wood-using industry studies conducted by the Forest Service from 1910 to 1913 in cooperation with various State offices and institutions. Of the total of 4,550,000,000 ' board feet reported, it is estimated that 700,000,000 log scale feet were used for veneer boxes and fruit and vegetable packages, leaving 3,850,000,000 board feet, lumber measure, or its equivalent of 7,700,000,000 square feet, for box shooks. This equivalent was calculated, for purposes of comparison, by assuming that the average box shook is about onehalf inch thick, and hence that a foot board measure is equal to two surface feet of shook. Further, of the 700,000,000 board feet, log scale, used for veneer containers, it is estimated that 250,000,000 feet were used for veneer boxes and an additional 50,000,000 feet for fruit and vegetable packages, which compete directly with the shook box. This total of 300,000,000 board feet, including 3 and 5 ply as well as single-ply veneer containers, is equivalent toabout 1,500,000,000 square feet of box shook, on the assumption that veneer materials average about one-eighth inch in thickness. Forest Service Circular 783 "Wood Used for Packing Boxes in New England," shows a consumption by box manufacturers of 600,493,000 board feet in 1905. The later State woo...
