For this purpose many offices use a card system similar to that employed by furniture dealers and others in connection with their sales on the instalment plan. One such card is maintained for each house and on it are entered the rents as they are paid. These cards are then sorted, and each day, or at frequent intervals, a certain number of them are given to the collectors, indicating to each the houses at which he is to call. As these calls are made, the collector turns back the proper cards to the office. The record is therefore necessarily divided, and is seldom, if ever, all in one place; also it occupies considerable space and is subject to loss and disarrangement.
In order to avoid these difficulties, the "Collector's Pocket Rent Ledger" (Form 38) was devised, the use of which requires no explanation. If printed on thin paper, a book about 4½ X 6½ inches, and about one-half inch thick, will contain the records of one thousand houses for one year. The space between any two heavy horizontal lines is devoted to one house or building, the blue lines indicating the first, second, third, fourth, and fifth weeks of each month. Each street has one or more pages allotted to it, and by arranging the streets alphabetically at stated intervals, the book can be kept in alphabetical order throughout its life. Being primarily for the use of collectors, the book contains no other record than that of rents collected.
