Note. Give one of them 7, and then divide the rest equally. 125. A gentleman divided an estate of $15000 between his two sons, giving the elder $2500 more than the younger. What was the share of each ! 126. A gentleman bequeathed an estate of $50000, to his wife, son, and daughter; to his wife he gave $1500 more than to the son, and to the son $3500 more than to the daughter. Wnat was the share of each ? 127. A, B, and C, built a house, which cost $35000; A paid $500 more, and C $300 less than B. What did each pay ? COWS. 128. A man bought a sheep, a cow, and an ox, for $62 ; for the cow he gave $10 more than for the sheep; and for the ox $10 more than for both. What did he give for each? 129. A man sold some calves and some sheep for $108; the calves at $5, and the sheep at $8 apiece. There were twice as many calves as sheep. What was the number of each sort? Note. There were two calves and one sheep for every $18. 130. A farmer drove to market some oxen, some cows, and some sheep, which he sods for $749; the oxen at $28, the cows at indtktractiut $7.50. There were twice as many cows as oxen, and three times as many sheep as How many were there of each sort ? 131. A man sold 16 bushels of rye, and 12 bushels of wheat for £8. 16s. The wheat at 3s. per bushel more than What was each per bushel ? Note. The whole of the wheat came to 36s. more than the same number of bushels of rye. Take out 36s., and the remainder will be the price of 28 bushels of rye. 132. Four men, A, B, C, and D, bought an ox for $50, which they agreed to share as follows: A and B were to have the hind quarters, C and D the fore quarters. The hind quarters were considered worth of cent per lb. more than the fore quarters. A's quarter weighed 217 lb.; B's 223 lb.; C's 214 lb. ; and D's 219 lb. The tallow weighed 73 lb., which they sold at 8 cents per lb. ; and the hide 13 lb., which they sold at 5 cents per lb. What ought cach to pay ? the rye. 133. At the time they bought the above ox, the fore quarters of beef were worth 6 cents per lb., and the hind quarters 61 cents per lb. It is required to find what each ought to pay in this proportion. Note. This is a more just manner of dividing the cost, than that in the last example. It may be done by finding what the quarters would come to, at this rate, and then dividing the real cost in that proportion. 134. Said A to B, my horse and saddle together are worth $150, but my horse is worth 9 times as much as the saddle. What was the value of each ? 135.

A man driving some sheep, and some cows, and some oxen, being asked how many he had of each sort, answered, that he had twice as many sheep as cows, and three times as many cows as oxen; and that the whole number was 80. Required the number of each sort. 137. A gentleman left an estate of $13000 to his four sons, in such a manner, that the third was to have once and one half as much as the fourth, the second was to have as much as the third and fourth, and the first was to have as much as the other three.

The stock of a cotton manufactory is divided into 32 shares, and owned equally by 8 persons, A, B, C, &c. A sells 3 of his shares to a ninth person, who thus becomes a member of the company, and B sells 2 of his shares to the company, who pay for them from the public stock. After this, A wishes to dispose of the remainder of his part. What proportion of the whole stock does he own? 140. Three persons, A, B, and C, traded in company. A put in $75; B $40; and C a sum unknown. They gained $64, of which C took $18 for his share. What did C put in ? 141. How many cubic feet in a cistern, 4 ft. 2 in. long, 3 ft. 8 in. wide, and 2 ft. 7 in. high ! A method of doing this by decimals has already been shown. It is now proposed to do it by a method called duodecimals. First, I find the square feet in the bottom of the cistern. 3 ft. 8 in. =3 ft. 4 ft. 2 in. = 48 ft. 2 ft. 7 in. = 217 ft. 2 %+1%; 4:22 819 + 1 + THET 301 til Ang. 3911 +7 + ter cubic feet in the cistern. I say is ofta is =ittit, I write down the 74 and reserve the ia ; then of 4 is it and 1. (which was reserved) is =25, which I write down. Then 3 times and 3 times 4 are 12. These added together make 15. te square feet. Then to find the cubic feet, I multiply this by 27. troruoti is = true, I write the 772p, and resewe the 144 ; then ja of is it and ii. (which were reserved) are linia +1; I write down the land reserve the in; then 112 of 15 are 88 and is (which was reserved) is 819:- 2 times are and 2 times in are and 2 times 15 are 30. Adding them together, it and it are = 7 + 777; I write the gia, and reserve the ja ; then i; and ia are is, and a (which was reserved) is 11 =lf The whole is 3913+ 13 -1425 S. we know that 12ths multiplied by 12ths will pro duce 144ths, and that make ; and, also, that 144ths multiplied by 12ths produce 1728ths, and that tåg make 11a, we may write the fractions without their denominators, if we make some mark to distinguish one from the other. It is usual to distinguish 12ths by an accent, thus ('), 144ths thus ("'), 1728ths thus (''), &c. 12ths are called primes • 144ths seconds; 1728ths thirds, &c. 144 ; 129 Cubic feet 39 5' 7 4:11 The operation is precisely the same as before. To adopt the language suited to this notation, we say, units multiplied by primes or primes by units produce primes, seconds by units produce seconds, foc. primes by primes produce seconds, seconds by primes produce thirds. Also 12 thirds make 1 second, 12 seconds 1 prime, 12 primes make 1 foot, whether long, square, or cubic. The same principle extends to fourths, fifths, foc. 142. How much wood in a load 4 ft. 8 in. high, 3 ft. 11 in. broad, and 8 ft. long? Note. Multiply the height ar breadth together, and divide by 2. See page 102. 143. How many square feet in a floor 16 ft. 8 in. wide, and 18 ft. 5 in. long ? 144. How much wood in a pile 4 ft. wide, 3 ft. 8 in. high, and 23 ft. 7 in. long ? 145. If 11 barrels of cider will buy 4 barrels of flour, and 7 barrels of flour will buy 40 barrels of apples ; what will 1 barrel of apples be worth, when cider is $2.50 per barrel ? 146. A person buys 12 apples and 6 pears for 17 cents, and afterwards 3 apples and 12 pears for 20 cents. What is the price of an apple and of a pear ? Note. At the second time he bought 3 apples and 12 pears for 20 cents, 4 times all this will make 12 apples and 48 pears for 80 cents ; the price of 12 ap les and 6 pears being taken from this, will leave 63 cents for 42 pears, which is i cent apiece 147.

There are two cisterns which receive the same quantity of water ; the firæt constantly loses & of what it receives ; after running 7 days, 10 barrels were taken from the second, and then the quantity of water in the two was equal.
