The necessity for a record from which each mortgage may be charged with interest as it becomes payable is obvious. The only form required for this purpose is a book made of analysis paper and having at least twelve money columns, one for each month, as indicated in Form 39.*

It is sometimes necessary to make monthly reports regarding mortgage interest. For such cases Form 40, taken from English practice, gives a convenient record and is particularly adapted to branch offices which have to report to the home office or to other branch offices located at a distance. The forms required for interest payable are identical with those for interest receivable.
