Contracts are annually made for the supply of Canada 
Yellow Pine timber, deals, and masts, yards, and bow¬ 
sprits for the Royal Navy, according to the following 
specifications and conditions : 
The Yellow Pine timber to be of the first quality, 16 inches square and 
upwards ; 20 feet long and upwards, and the spine must be seen from the 
butt to the top on each of the four sides. 
The Yellow Pine deals to be of the first quality, bright, 3 inches thick, 
not less than 11 inches broad, and 12 feet long and upwards. The whole 
to be clean and bright in quality. 
All the Yellow Pine masts, yards, and bowsprits to be perfectly straight, 
well and in a workmanlike manner wrought; the masts, yards, and bow¬ 
sprits not to be hewn into eight squares, but all to be left in the square, 
similar to 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 partners, 
and in their four squares as aforesaid ; nevertheless, it is not expected that 
no sap shall remain at the edges of the said four squares ; but it will be 
judged sufficient if such masts, yards, and bowsprits are capable of being 
cleared of sap when brought into their usual squares.
