Reference has already been made to the loss sometimes entailed in granting this privilege. In the case of checks cashed at par by another branch, the ledger-keeper should make, in the ledger account opposite the entry of the check, a memorandum showing the date of encashment. The check becomes a charge against the account as soon as it is paid by the other branch. The analysis of some accounts in regard to items in transit and checks paid at par will frequently afford surprising results in the dissolving of apparently substantial balances.
