thoroughly air-seasoned boards 1" and 1^" in thickness it will be noted 
in examining the figures for this Division in Appendix I to w'hat extent 
the various species have seasoned according to each method. It is to 
be understood that the following figures are isolated determinations 
and do not establish the actual hmits of thickness in which thorough 
air-seasoning has taken place. For example, under (1) it will be noted 
that Chloroxylon Swietenia is thoroughly air-seasoned up to a thick- 
ness of . It is not known whether or not thicker material is also 
completely seasoned.
