METHOD OF MEASURING ROUGH TREES FOR MASTS. The length to be 3 times, in feet, what the diameter is in inches at the partners, adding 9 feet. The measuringplace for the partners is 2/3, in feet, from the butt what the mast measures in inches at the partners. The hounds to be set back from the length at half the distance from the butt to the partners; and from the hounds to the partners to be divided into 4 equal parts, called quarters. The quarters, hounds, and heel, to bear the following proportions to the diameter at the partners: viz. First quarter, 60/61; second quarter, 13/14; third quarter, 6/7; hounds, 2/3; and heel, 5/6. HANDMASTS to be of the sizes at the partners as in the Table of the Value of Fir Timber; which is, 8 inches from the butt for every hand in circumference. (that is, supposing the circumference to be 6 hands, the distance of the partners from the butt is 6 times 8, or 48 inches,) and 11/12 that bigness in the middle between the partners and the top, there to girth 2/3 the bigness of the partners. The length is governed in proportion to the number of hands in circumference at the partners, as follows: Add 6 inches to the number of hands, and multiply by 3, the product is the length in feet and inches. Or, multiply the number of hands by 3 and add 18 feet. – Four inches make a hand. BOWSPRITS to be in length 2/3, in yards, what the diameter is in inches at the bed or measuring place, that being 2/3 in feet from the butt what the bowsprit is intended to measure in inches at that place. MASTS from America are mostly trimmed in the country nearly to their sizes, so that the diameter and length as per Table is sufficient. YARDS to be in length as per Table, and to hold that diameter in the middle, and half that diameter at the ends. DUTIES ON MASTS PAYABLE IN GREATBRITAIN.
