stands. The Dr. accounts are placed on the left hand of the page, and the Cr. accounts on the right hand, and each item should refer by numbers to the page of the Day-book on which it may be found; while each sum of items of the Day-book should refer to the page of the Ledger on which it will be found. Every Ledger should also contain an index, in which all the names it contains should be alphabetically arranged, with the page of the Ledger on which the person's account can be found.

The Cash-book should contain a record of the payments and receipts of cash as they occur from day to day; but all money received on any person's account should be entered to his credit on the Day-book; so with money paid to any person on account.

Persons making but few entries in their business, and requiring but one book for their accounts, might adopt the Ledger form, and appropriate a page to each person's account, using the book for original entries.

The circumference of the earth is divided into three hundred and sixty degrees. The sun passes over one degree in every four minutes therefore, or seems so to pass, by the revolution of the earth on its axis. If, therefore, you desire to know what time it is at any other point on the earth, ascertain from your map your own longitude and the longitude of the place you have in view; multiply the number of degrees of longitude between the two points by four, and the product will be the difference in time, in minutes, between the two points. If the product be more than sixty, divide such product by sixty, and your quotient will be hours, and your remainder will be minutes. If the place be east of you, add the time to the time at your own place, and the sum will be the time at the point required; but if the place be west of you, subtract the result from your time, and the remainder will be the time at the place required. In making your calculation you must bear in mind that clocks usually mark only twelve hours instead of twentyfour, and that one hour after twelve the clock marks one again at all points of the earth.
