2. 8cwt. 2qrs. 16lb. at 21. 5s. 6d.

of 871. 13s. 4d. or 81. 15s.

manner, as 4d. is of 3s. 4d. so 4d. is the answer at 4d. And by reasoning in this way 41. 7s. 8d. will be shown to be the price at 2d. and 10s. 114d. the price at 1-Now as the sum of all these parts is equal to the whole price (3s. 101d.) so the sum of the answers, belonging to each price, will be the answer at the full price required. And the same will be true in any example whatever.

TARE AND TRETT.

Tare and TRETT are practical rules for deducting certain allowances, which are made by merchants and tradesmen in selling their goods by weight.

Tare is an allowance, made to the buyer, for the weight of the box, barrel, or bag, &c. which contains the goods bought, and is either at so much per box, &c. at so much per cwt. or at so much in the gross weight.

Trett is an allowance of 4lb. in every 104lb. for waste, dust, &c.

Cloff is an allowance of 2lb. upon every 3cwt.

Gross weight is the whole weight of any sort of goods, together with the box, barrel, or bag, &c. that contains them.

Suttle is the weight, when part of the allowance is deducted from the gross.

Net weight is what remains after all allowances are made.

CASE 1.

When the tare is a certain weight per box, barrel, or bag, &c.

RULE.*

Multiply the number of boxes, or barrels, &c. by the tare, and subtract the product from the gross, and the remainder is the net weight required.

• It is manifest, that this, as well as every other case in this rule, is only an application of the rules of Proportion and Prac⚫ tice.

EXAMPLES.

1. In 7 frails of raisins, each weighing 5cwt. 2qrs. 5lb. gross, tare 23lb. per frail, how much net?

2. In 241 barrels of figs, each 3qrs. 19lb. gross, tare 10lb.

per barrel, how many pounds net?

Ans. 22413.

3. What is the net weight of 14 hogsheads of tobacco, each 5cwt. 2qrs. 17lb. gross, tare 100lb. per hhd.?

CASE 2.

Ans. 66cwt. 2qrs. 14lb.

When the tare is a certain weight per cwt.

RULE.

Divide the gross weight by the aliquot parts of a cwt. contained in the tare, and subtract the quotient from the gross, and the remainder is the net weight.

EXAMPLES.

1. Gross 173cwt. 3qrs. 17lb. tare 16lb. per cwt. how much

net?

2. What is the net weight of 7 barrels of pot-ash, each weighing 201lb. gross, tare being at 10lb. per cwt.?

Ans. 1281lb. 6oz.

3. In 25 barrels of figs, each 2cwt. 1qr. gross, tare 16lb. per cwt. how much net?

Ans. 48cwt. 24lb.

CASE 3.

When Trett is allowed with Tare.

RULE.

Divide the suttle weight by 26, and the quotient is the trett, which subtract from the suttle, and the remainder is the net weight.

EXAMPLES.

1. In 9cwt. 2qrs. 17lb. gross, tare 37lb. and trett as usual,

2. In 7 casks of prunes, each weighing 3cwt. 1qr. 5lb. gross, tare 17 lb. per cwt. and trett as usual, how much net? Ans. 18cwt. 2qrs. 25lb.

3. What is the net weight of 3 hogsheads of sugar weighing as follows: the first, 4cwt. 5lb. gross, tare 73lb. the second, 3cwt. 2qrs. gross, tare 56lb. and the third, 2cwt. 3qrs. 17lb. gross, tare 47lb. and allowing trett to each as usual? Ans. 8cwt. 2qrs. 4lb.

CASE 4.

When tare, trett, and cloff are all allowed.

RULE.

Deduct the tare and trett, as before, and divide the suttle by 168, and the quotient is the cloff, which subtract from the suttle, and the remainder is the net.

EXAMPLES.

1. What is the net weight of a hhd. of tobacco, weighing 15cwt. 3qrs. 20lb. gross, tare 7lb. per cwt. and trett and cloff as usual?
