TARE and TRE T.

Tare and Tret are practical rules for deducting certain allowances, which are made by merchants and tradefmen in felling 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 fo much per cwt. or at so much in the gross weight.

Tret is an allowance of 4ft in every 1041b for waste, duft, &c.

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

Grofs weight is the whole weight of any fort of goods, together with the box, barrel or bag, &c. which contains them.

Suttle is when part of the allowance is deducted from the grofs.

Neat weight is what remains after all allowances are made.

CASE

CAS E I.*

When the tare is at so much per box, barrel or bag, &c.—-Multiply the number of boxes, barrels, &c. by the tare, and fubtract the product from the grofs, and the remainder will be the neat weight required.

EXAMPLES.

1. In 6 hogheads of fugar, each weighing 9cwt. 2qrs. 10ft grofs, tare 25 per hogfhead; How much

neat?

CASE

This, as well as every other Cafe in this rule, is only an appli

cation of the rules of Proportion and Practice,

[blocks in formation]

When the tare is at so much per cwt.-Divide the grofs weight by the aliquot parts of a crut. Subtract the quo

tient from the grofs, and the remainder will be the neat weight.

EXAMPLES.

I. In 129cwt. 3grs. 16lb grofs; tare 14tb per cut. What neat weight?

[blocks in formation]

When the tret is allowed with tare ;-Divide the futtle weight by 26, and the quotient will be the tret, which fubtract from the futtle, and the remainder will be the

neat.

2. What is the neat weight of 4hhds. of tobacco, weighing as follow; the 1ft, 5cwt. 1qr. 12lb. grofs; tare65lb. per hogfhead; 2d, 3cwt. oqr, 19lb. gross; tare 75lb.; the 3d, 6cwt. 3qrs. grofs, tare 49lb.; and the 4th, 4cwt. 2qrs. 9lb. grofs; tare 35lb. and allowing tret to each as ufual? Anf. 17cwt. ogr. 19lb.

CAS E IV.

When tare, tret and cloff are allowed ;-Deduct the tare and tret as before, and divide the futtle by 168, and the quotient will be the cloff, which fubtract from the futtle, and the remainder will be the neat.

EXAMPLES.

1. What is the neat weight of a hogfhead of tobacco, weighing 16cwt. 2qrs. 20lb. grofs; tare 14lb. per cwt. tret 4lb. per 104, and cloff 2lb, per 3cwt. ?
