If it is deemed best to teach Decimal Fractions before United States Money, introduce Section XI (page 192) at this point. Art. 79. United States Money is the legal currency of the United States. It is also called Federal Money. The denominations are mills, cents, dimes, and dollars. NOTES.-1. United States money consists of Coin and Paper Money. Coin is called Specie Currency, or Specie, and paper money is called Paper Currency. 2. The principal gold coins are the eagle ($10), half-eagle ($5), quarter-eagle ($23), three-dollar piece, and dollar. The silver coins are the dollar, half-dollar, quarter-dollar, dime, half-dime, and three-cent piece. The nickel coins are the five-cent piece, three-cent piece, and cent. The copper coins (old) are the two-cent piece and the cent. 3. Paper money consists of notes issued by the United States, called treasury notes, and bank notes issued by banks. 4. Treasury notes of a value less than $1, as fifty cents, twenty-five cents, fifteen cents, ten cents, five cents, and three cents, are called Fractional Currency. 1. How many mills in 1 cent?

The figures denoting dollars are preceded by the sign, $. The first two figures at the right of dollars denote cents, and the third figure denotes mills. The figures denoting dollars are separated from those denoting cents by a period (.), called a Separatrix. Thus, $45.307 is read 45 dollars, 30 cents, 7 mills. NOTE. The pupil should here be taught that the first figure at the right of the separatrix denotes tenths of a dollar; the second, hundredths; the third, thousandths. He should also be taught to read the following numbers decimally, and to write similar numbers, when dictated, decimally. The first decimal period may thus be mastered. 17. Write in figures 4 dollars 40 cents. 18. Write 12 dollars 33 cents 5 mills. 19. Write 60 dollars 6 cents 4 mills. 20. Write 75 cents 5 mills. 21. Write 30 cents; 40 cents 7 mills. 22. Write 300 dollars 3 cents 7 mills. 23. Write 500 dollars 5 mills. 24. Write 25 cents 7 mills; 6 cents 1 mill. 26. Write 1000 dollars; 50 dollars 5 cents. 29. Write 5 mills; 5 cents 5 mills.
