Both methods will obtain the same result; the former is generally used. NOTES. 1. When hours are to be obtained, we reckon from 12 at night, and if minutes and seconds, we write them still at the right of hours. 2. In finding the time between two dates, or in computing interest, 12 months are considered a year, and 30 days a month. When the exact number of days is required for any period hot exceeding one ordinary year, it may be readily found by the following TABLE, Showing the number of days from any day of one month to the same day of any other month within one year.

If the days of the different months are not the same, the number of days of difference should be added when the earlier day belongs to the month from which we reckon, and subtracted when it belongs to the month to which we find the time. If the 29th of February is to be included in the time computed, one day must be added to the result. EXAMPLES FOR PRACTICE. 2.

A farmer has 8 fields, each containing 4 A. 2 R. 27 P.; how much land in all? OPERATION. 4 2 27 8 37 1 16 ANALYSIS. In 8 fields are 8 times as much land as in 1 field. We write the multiplier under the lowest denomination of the multiplicand, and proceed thus; 8 times 27 P. are 216 P., equal to 5 R. 16 P.; and we write the 16 P. under the number multiplied. Then 8 times 2 R. are 16 R., and 5 R. added make 21 R., equal to 4A. 1 R.; and we write the 1 R. under the number multiplied. Again, 8 times 4 A are 32 A., and 4 A. added make 36 A., which we write under the same denomination in the multiplicand, and the work is done. Hence, RULE. I. Write the multiplier under the lowest denomination of the multiplicand. II. Multiply as in simple numbers, and carry as in addition of compound numbers. Multiplication of compound numbers, how performed? Rule. 8. In 6 barrels of grain, each containing 2 bu. 3 pk. 5 qt., 9.
