 Circ. 122, PI). .'/,?). — Statistical data prepared jointly by the Bureau of the Census 

 and the Forest Service are given, showing the value and amount of lumber pro- 

 duced in the United States in IWX; by species, States, and classes. The data 

 are based upon reports from 22,398 lumber manufacturers, and show a pro- 

 duction of 37,550,736,000 ft., with a mill value of $621,151,388, in addition to 

 which there were produced 11,858,260,000 shingles and 3.812,807.000 laths. The 

 \-ombined value of lumber, lath, and shingle production for 1906 was $656,- 

 7fK5,513. Comparative data are given from 1899 to 1904 based upon the censuses 

 of 1900 to 1905. 



Although no detailed reports were received from Alaska, the total cut of the 

 Alaskan mills in 1906 approximated 16,000,000 ft., of which about 1.5,000,000 ft. 

 was spruce and the rest mainly cedar. 



Consumption of pulpwood in 1906 {V. S. Dept. Agr., Forest Serv. Circ. 

 120, pp. 10). — Statistical data collected and compiled jointly by the Bureau 

 of the Census and the Forest Service are given, showing the consumption of all 

 kinds of pulpwood in 1906. The total consumption by 250 mills was 3.661. 17(i 

 cords, or an increase of 469.053 cords over that of the previous year. 



Detailed tables are given showing the kinds, amounts, and value of wood 

 used in the production of puljj by species, States, and by the mechanical, sul- 

 phite and soda processes, together with comparative data showing the total 

 amount of wood used for pulp in the mechanical and chemical processes in 

 1899. 1905, and 1906, and the imports and exports of wood-pulp for the period 

 from 1002-lt)06. The amount of wood imported from Canada for pulp in- 

 creased from 369,217 cords in ISlKt to 738,872 cords in 1906. The total imports 

 of wood-pulp in 1900 amounted to 157,224 tons, valued at $4,584,942, and the 

 total exports amounted to 14.741 tons, valued at .$587,878. It is estintated that 

 the United States is exporting six-tenths of 1 per cent and importing 6.7 per 

 cent of the total consumption of wf)od-pulp. 



Consumption of cross-ties in 1906 (f. S. Jjrpt. Agr., Forest Herv. Circ. 12'i, 

 pp. G). — Statistical data collected by the Bureau of the Census in conjunction 

 with the Forest Service are given, showing the estimated consumption of cross- 

 ties in 1906. based on the number of ties bought during a 12-month period. 



Detailed tables show the kinds, number, and \alue of hewed and sawed ties 

 purchased by steam railroads in l!t05 and 1!)()6, as well as those i)urchased by 

 street railroads in 1906. The total number of cross-ties purchas«>d by steam 

 and street railroads in the I'nited States during the latter year was 102,8.34,- 

 042. valued at $48,819,124, or an average of 47 cts. per tie at the point of pur- 

 chase. The steam railroads purchased about nine-tenths of the whole number. 



The preservative-treated ties purchased by steam and street railroad com- 

 panies amounted to 5,289,435, in addition to which 6,490,203 ties were treated 

 at the company plants. The greater use of preservatives ties, which in 1906 

 amounted to 11.5 per cent of the whole number purchased, is due to the in- 

 creasing necessity of using iiine and other less decay-resistant woods. 



Production of slack cooperage stock in 1906 ( U. .S. Dept. Agr., Forest Serv. 

 Circ. 123, pp. ,S').— Statistics were secured l)y the Bureau of the Census in con-
