Contracts are annually made for the supply of Canada Yellow Pine timbwer, 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 bowsprits 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.
