A premium price is paid for timber suitable for keel- 
pieces ; logs qualified for this purpose are not to exceed 
250 feet cube. 
The conditions of the contract are— 
1. That all the timber shall be felled in the winter ; 
that is, within the 1st November and the end of 
February. 
2. The timber will not be required to be delivered of 
an octagonal form, but must be so hewn or squared as 
that at each of the measuring places no surface or square 
shall be less than one-fourth of the diameter of the piece 
where the measurement is to be taken (Fig. 262) ; and in 
measuring at the yards, the contents of the butt-lengths 
will not be taken separately, but the lengths for measure- 
ment will be regulated by the several stops or joggles.
