SPECIFIC DESCRIPTIONS. 



Notwithstanding the very general substitution of other materials like con- 

 crete, metals, stone, and clay for wood there is no clear indication that the 

 call for lumber and other forest products is decreasing at this time. With 

 the opening of the Panama Canal and the changing conditions which are con- 

 stantly taking place in trade, it is difficult to predict what the future will 

 bring forth. As it is there is a large demand for lumber of all kinds and es- 

 pecially for the better grades of native woods. If there were an inexhaustible 

 supply of timber now as there appeared to be fifty years or more ago, there 

 would be less reason for making a study of this kind; but on account of the 

 growing shortage of commercial timber it is most important that investiga- 

 tions be made to determine the qualities of woods that best fit them for a 

 particular use. With this in view, this section of the report has been de- 

 voted to a brief account of the several woods used by the manufacturers.
