*** By this table may be compared the least, mean, and greatest strength of the several spe- 
cies of timber, thus : — 
weakest English Oak : strongest Elm : : 1105-1 : 1044-? 
The mean strength of Dantzic Oak is the same as the greatest strength of Adriatic Oak, s. 
that the scantlings of the former are those of the latter. 
By means of the relative values of S may be found, if requisite, the scantlings for the 
weakest or strongest of the various species of timber.
