On some timbers which resist the attack of termites, R. Kanehiea (Indian 

 Forester, JfO {19U), No. 1, pp. 23-41). — The author here presents a list of con- 

 struction timbers which have been found resistant to the attack of termites in 

 various tropical countries, together with a list of seasoned and unseasoned 

 Formosan timbers showing their relative immunity when inspected at intervals 

 of 6 months and a year after burying. From the experiments thus far made it 

 is concluded that the termite resistance of various timbers may be due to the 

 presence in the wood of certain species of some substance with a strong smell 

 or taste disagreeable to insects ; to the presence of poisonous subtances in cer- 

 tain species ; and to the extreme hardness of the wood in others.

 prietors or employees ; primary horsepower ; capital ; wages ; cost of materials ; 

 value of products; and value added by manufacture. Comparative data are 

 also given for previous census periods. 



The total number of establishments reporting was 44,804 ; the number of per- 

 sons engaged in the industry, 797,825; the amount of capital invested, $1,182,- 

 330,552; the value of products, $1,160,644,628; and the value of products less 

 cost of materials, $652,425,475. The statistics relative to lumber, lath, and 

 shingle production correspond to those previously issued (E. S. R., 25, p. 240). 



Wood-using industries of Ohio, C. W. Dunning (Ohio Sta. Wood-Using

 of the wood-using industries of Ohio, conducted cooperatively by the Forest 

 Service of the U. S. Department of Agriculture and the Ohio Station. The 

 data given and discussed show the consumption and value of domestic and im- 

 ported woods by species and by industries, including also the kinds of woods 

 used by each industry, and the average cost per thousand feet. A list is also 

 given showing the use of domestic and foreign woods in the manufacture of 

 various articles, together with a directory of wood-using manufacturers. 



In order to make the report more complete the statistics of the Bureau of the 

 Census referring to Ohio have been compiled and are here given.
