This rule teaches the method of deducting such allowances as are usually made by merchants and tradesmen in selling their goods; and the terms in general use are gross weight, tare, tret, suttle, and neat weight. Gross weight is the whole weight of the goods, together with the box, barrel, bag, chest, &c. that contains them. Tare is an allowance made to the buyer, for the weight of the box, barrel, &c. This is charged either at so much per box, &c., or at so much per hundred weight, or at so much in the whole. Tret is an allowance of 47b. in every 1047b. (i. e. a 26th part of the whole) for waste, dust, &c. Suttle weight is when part of the allowance is deducted from the gross. Neat or net weight is that which remains after all allowances are made. § 115. CASE 1. When the tare is so much in the whole. RULE. Subtract the tare from the gross, and the remainder will be the neat weight. EXAMPLES. 1. In 17 barrels of rice, weighing in the whole 36cwt. 3qr. 676. gross, and tare in the whole 3cwt. Oqr. 197b., how much neat weight, and what is the amount, at $4.25 per cwt.?. 2.

The gross weight of 3 loads of hay is 3 T. 2cwt. 1qr., and tare in the whole 6407b., how much neat weight, and what is the amount, at $8.92 per ton? 5. What is the neat weight of 5 casks of sugar, weighing as follows: No. 1, 4cwt. 2qr. 147b. gross, tare 21lb. No. 2, 3cwt. Oqr. 17lb. gross, tare 187b. No. 3, 5cwt. 3qr. 10lb. gross, tare 1qr. 117b. No. 4, 6cwt. 1qr. 16lb. gross, tare 277b. No. 5, 3cwt. 3qr. 18lb. gross, tare 197b.? And what would be the value of the whole, the first three being worth $9.44 per cut. neat, and the other two $9.64 per cwt. neat? § 116. CASE 2. When the tare is at so much per box, bag, barrel, &c. RULE. Multiply the number of boxes, &c. by the tare, and subtract the product from the gross, and the remainder will be the neat weight. EXAMPLES. 1. What will be the neat weight of 36 bales of silk, weighing in the whole 74cwt. Oqr. 167b. tare 177b. per bale? 2.
