The chief advantage of this ledger is that it affords opportunity for making a daily proof of the balances shown on it, and of comparing same with balance of individual deposits shown by the general ledger. In this way the correctness of each day's work is tested by itself, and errors made in the postings are more readily found than when a ledger is proved but once a month. It is not as convenient for writing up and comparing pass-books, and involves more labor than the balance column ledger, because the balance of each and every account, whether it has changed or not, has to be carried forward to the next day's column, before the ledger can be proved.

A form of ledger recently patented, known as the "Rand's Patented Individual Ledger and Index Book,' manufactured by the Rand Ledger Co., North Tonawanda, N. Y., appears to combine the best features both of the "balance column" and "daily balance" ledgers, as it is substantially the balance column ledger divided into sections of twenty or more leaves by a leaf of stiff cardboard, the margin of which projects beyond the leaves, upon which margin are metal slides, into which slips of paper bearing the names of depositors are first inserted, space being left at the outer end of each slide sufficient to contain a slip of paper, upon which the balance of the depositor is written. Every time any balance changes the slip is removed and a new slip, showing the changed balance, is inserted instead. The device admits of making a daily proof of all balances, and still saves the labor of carrying forward those balances which have undergone no change during the day. Full information can be obtained from the company making these ledgers.

Whatever kind of individual ledger is used, deposits or other entries should be made by the bookkeepers from the "deposit tickets" furnished by the receiving teller, and debits should be made from checks paid by the paying teller or deposited with the receiving teller. All entries when made should be checked, if possible, by some other person than the keeper of the ledger, and the bookkeeper should aggregate the credits and debits entered for the day and compare his aggregates with the receiving and paying tellers' totals of deposits received and checks paid, respectively. Where there are two or more individual ledgers, the bookkeepers should be made to change ledgers from time to time, or be "rotated," as a further check to possible fraud or dishonesty. When the balance column ledger is used, some additional safeguard is afforded by having some person other than the bookkeeper take off a trial balance unexpectedly and without previous notice; but the most efficient check is the frequent and constant comparison of depositors' pass-books with their accounts on the ledger by some person other than the bookkeeper, as already recommended.
