TARE and Trett are practical Rules for deducting certain allowances which are made by merchants, in buying and selling goods, &c. by weight; in which are noticed the following particulars: 1. Gross Weight, which is the whole weight of any sort of goods, together with the box, cask, or bag, &c. which contains them. 2. Tare, which is an allowance made to the buyer, for the weight of the box, cask, or bag, &c. which contains the goods bought, and is either at so much per box, &c.-or at so much per cwt. or at so much in the whole gross weight. 3. Trett, which is an allowance of 4 lb. on every 104 lb. for waste, dust, &c, 4. Cloff, which is an allowance made of 2 lb. upon every 3 cwt. 5. Suttle, is what remains after one or two allowances have been deducted. CASE I. When the question is an Invoice.-Add the gross weights into one sum and the tares into another; then subtract the total tare from the whole gross, and the remainder will be the neat weight.
