The interest allowed should be altogether greater than the regular rate, so as to make the advantage of it in the case of such small sums appreciable to the children--but not too great.

Some judgment and discretion must be exercised on this as on all other points connected with the system.
The arrangements for the keeping of an account being made, and the account opened, there is, of course, no necessity, as in the case of payments made simply in cash, that the business should be transacted at stated times.

At any time when convenient, the entry may be made of the amount which has become due since the time of the last entry.

And when, from time to time, the child wishes for money, the parent will look at his account and see if there is a balance to his credit.

If there is, the child will be entitled to receive whatever he desires up to the amount of the balance.
