=25.= To save rewriting the names of the accounts each month, a trial balance book can be used to good advantage. These books are made to accommodate six trial balances on a double page, and are sometimes made with alternate short leaves so that twelve trial balances may be made with one writing of the names. When the trial balance book is used, care must be exercised in providing space for the addition of new accounts in each section. Where separate sales and purchase ledgers are used, it is best to provide a trial balance book for each ledger. THE CHECK REGISTER =26.= Large check books are cumbersome to handle and necessitating the expenditure of much needless labor. Their use is rapidly giving way in modern offices to the check register. The check register has several distinct advantages. It exhibits, in compact form, a record of all checks issued and can also be arranged to show deposits and balance in the bank. Distribution columns can be provided with headings for the different expenditure accounts, which makes of the check register a cash expenditure book. The form should be varied to suit the business in which it is to be used. A typical form is illustrated on page 37. =27. Checks in Pads.= When the check register is used it is the usual custom to have checks put up in pads. After the check is written, it is registered and numbered to correspond to the register number. With the use of padded checks, it is not necessary for the clerk who writes the check to know anything about the bank balance. [Illustration: Trial Balance Book ] [Illustration: Check Register Combined with Cash Expenditure Book ] [Illustration: Cash Received Book ] [Illustration: Checks in Pads ] CASH RECEIVED BOOK =28.= A cash book specially ruled for a record of cash received is used to supplement the check register or cash expenditure book. Columns are provided for the different classes of receipts, with one credit column. It is assumed that all cash received is deposited, payments being made exclusively by check. This does not refer to petty cash expenditures which should be kept in a petty cash book or on envelope vouchers.
