Wood prepared for the market is generally 4 feet long, and a load in a wagon generally contains two lengths, or 8 feet in length. If a load is 4 feet high and 4 feet wide, it contains a cord. It was remarked above, that what is called one foot of wood, is 16 solid feet, and that 8 such feet make 1 cord. To find how many of these feet a pile or load of wood contains, it is necessary to find the number of solid feet in it, and then to divide by 16. When the load of wood is 8 feet long, we may multiply the breadth and height together, and then, instead of multiplying by 8, and dividing by 16, we may divide at first by 2, and the same result will be obtained. 22. How many feet of wood in a load 8 feet long, 3 ft. 4 in. wide, and 2 ft. 7 in. high? 23. How many feet of wood in a load 8 feet long, 3 ft. 7 in. wide, and 5 ft. 2 in. high? 24.

Suppose a certain town is to pay a tax of $6145.88, and the whole property of the town is valued at $153647; what is that on a dollar? How much must a man pay, whose property is valued at $23475.67 ? Note. In assessing taxes, the first requisite is to have an inventory of the property, both real and personal, of the whole town or parish, and also of each individual who is to be taxed, and the number of polls. The polls are always stated at a certain rate. Then knowing the whole tax, take out what the polls amount to, and the remainder is to be laid upon the property. Find how much each dollar is to pay, and make a table, containing the portion for 1, 2, 3, &c. to 10 dollars, then for 20, 30, 40, &c. to 100, and then for 200, 300, &c. From this table it will be easy to find the tax upon the property of any individual. 32. A certain town is taxed $3137.43. The whole property of the town is valued at $89640.76. There are 120 polls which are taxed $.75 each. What is the tax on a dollar? How much is a man's tax who pays for 3 polls, and whose property is valued at $2507 ? 33. A merchant bought wine for $1.75 per gallon, and sold it for $2.25 per gallon. What per cent. did he gain? Note. He gained 50 cents on a gallon, which is of the first cost. It has been already remarked that 1 per cent. is .01, 2 per cent. is .02, &c.; that is, the rate per cent. is always a decimal fraction carried to two places or hundredths. To find the rate per cent. then, first make a common fraction, and then change it to a decimal .285. Now .28 is 28 per cent. and .0055 is55 per cent. The rate then 28555 per cent. The two first decimal places taken together being hundredths are so much per cent., and thousandths are so many tenths of one per cent, 34.
