tions is in these smaller than in hardwoods. The tests on longi- 

 tudinal sections is although unsafe, for here elasticity of fibers 

 is a disturbing factor. 



Some divergences from the relation of hardness and specific 

 weight are met with the doubtful suggestion that wood from 

 different localities does not follow the law as the author claims 

 also to have established in regard to compressive strength. 



The author claims, however, that, in general, his data show not 

 only a direct relation between hardness and specific weight but 

 also between hardness and compression strength. An attempt to 

 relate hardness to bending strength was also made with unsatis- 

 factory results. 



That the technical qualities including hardness are a function 

 of the summerwood per cent, are specially brought out in the 

 tests of spruce, and altogether for spruce the proportionality of 

 the different exhibitions of strength to the hardness are satisfac- 

 torily shown. 



The simplicity of this hardness test, the author thinks should 

 encourage its use to determine the relation of hardness to other 

 qualities and perhaps eventually to substitute the hardness tests 

 for all other tests. 



The reviewer would point out that although the relation of the 

 compression strength to cross bending and other strength is 

 obvious and has been mathematically established by Mr. Neely 

 from the tests of the U. S. Forestry Division, so conservative are 

 the test engineers that they would not benefit from the discovery 

 which would curtail much of their work both at the machines and 

 in the computations.
