Note. In reducing rods to Note. Here we have 776457 feet, the multiplier will be square feet to be divided by 2721. To multiply by, is to 2724. Reduce the divisor to take a fourth part of the mul-fourths, that is, to the lowest tiplicand. The principle is denomination contained in it; the same as shown T 34, then reduce the dividend to

SOLID OR CUBIC MEASURE.

Solid or cubic measure is used in measuring things that have length, breadth, and thickness; such as timber, wood, stone, bales of goods, &c. The denominations are cords, tons, yards, feet, and inches.

T 36. It has been shown, that a square yard contains 3 X 39 square feet. A cubic yard is 3 feet long, 3 feet vide, and 3 feet thick. Were it 3 feet long, 3 feet wide, nd one foot thick, it would contain 9 cubic feet; if 2 feet hick, it would contain 2 X 918 cubic feet; and, as it is 3 feet thick, it does contain 3 x 927 cubic feet. This

It is plain, also, that a cubic foot, that is, a solid, 12 inches in length, 12 inches in breadth, and 12 inches in thickness, will contain 12 X 12 X 12 = 1728 solid or cubic inches.

¶ 37. The year is also divided into 12 calendar months, which, in the order of their succession, are numbered as follows, viz.

January, 1st month, has 31 days.

February, 2d,

[ocr errors]

[blocks in formation]

The number of days in each month may be easily fixed in the mind by committing to memory the following lines:

Thirty days hath September,
April, June, and November,
February twenty-eight alone;
All the rest have thirty-one.

The first seven letters of the alphabet, A, B, C, D, E, F, G, are used to mark the several days of the week, and they are disposed in such a manner, for every year, that the letter A shall stand for the 1st day of January, B for the 2d, &c. In pursuance of this order, the letter which shall stand for Sunday, in any year, is called the Dominical letter for that year. The Dominical letter being known, the day of the week on which each month comes in may be readily calculated from the following couplet:

At Dover Dwells George Brown, Esquire,
Good Carlos Finch And David Fryer.

These words correspond to the 12 months of the year, and the first letter in each word marks the day of the week on which each corresponding month comes in; whence any other day may be easily found. For example, let it be required to find on what day of the week the 4th day of July falls, in the year 1827, the Dominical letter for which year is G. Good answers to July; consequently, July comes in on a Sunday; wherefore the 4th day of July falls on Wednesday.

Note. There are two Dominical letters in leap years, one for January and February, and another for the rest of the year.
