While the number of these societies is perhaps decreasing-, many are still in active business. The details connected with their work, however, lie outside the limits of the real estate office and of the present volume. In a general way it may be said, that these companies depend upon the interest and fees which they charge their borrowers, the former being calculated by one of the methods described in Chapter XIX (Interest. Section 134. Mortgage Interest).
The question of ascertaining the profits of such societies is not a difficult one when proper tables are prepared to facilitate the apportionment of receipts and outstanding mortgages between the income and investment accounts. The use of a columnar ledger or columnar journal frequently results in a great saving of time, and yields clearer results than do the more usual forms.
