more wane at any part than 4 inches on the two wanes taken together ; or, 
if there is no wane on one edge or angle, and it is only on the other edge or

The compass timber to be sided from 7 to 20 inches, inclusive, and no 
part thereof, except of from 7 to 11% inches sided, to be less than 13 feet 
in length. 
The transverse strength of Italian Oak is shown in 
Tables XXVII., XXIX., and XXX., and the vertical 
strength in Tables XXVIII. and XXXL. but there are 
fewer experiments on these than on most other woods, 
owing to the difficulty that was found in obtaining a 
length of seven feet with a clean straight grain for 
testing.
