 specifications and conditions : — 



The Yellow Pine timber to be of the first quality, 13 inches square and

 mast timber, and to have most of their sap taken out. 



The masts, yards, and bowsprits are not to be tapered from their partners 

 downwards, but to be kept as big at the heel as they are at the paitners, and 



* I am informed that this specification is not now in use, but I retain it as a 

 suitable one for mast timber.
