is then sent at once through the mail to formally notify the cus- 

 tomer of his indebtedness. 



Another method which has been employed consists in the use 

 of the time-book, made to fit in the pocket, and which the man on 

 the delivery wagon carries. The names of customers in the account 

 book should follow the same order as that observed in visiting them 

 on the milk route. See page 344 for forms used in keeping ac- 

 counts. This book is ruled so that when the book is opened there 

 are columns on each two pages, facing one another, for all the 

 days of the month. The customers' names are written down in a 

 column on the left-hand edge of the page and his account kept 

 on a horizontal line extending across the two open pages. Two 

 such books are used, the delivery man having one on one day and 

 the other book the following day, so that each day one book may 

 be turned into the office for inspection., On each day two of the 

 perpendicular columns are used for each customer. In the first 

 column is entered the amount of milk or' cream taken and in the 

 second column the. number of bottles returned. This method is not 

 so good as the preceding. In order to avoid trouble it is neces- 

 sary for every firm distributing any considerable amount of milk to 

 have a special man who shall be familiar with the customers on each 

 milk route in case of sudden failure of a driver to attend to his 

 duties. 



If the milk is to be marketed in the best possible manner, 

 especially if sold for infants' use, there should be placed a parch- 

 ment paper bottle cap over the ordinary cardboard cap. The ob- 

 ject of this extra paper cap, which is waterproof, is to prevent 

 dust, dirt, and water (from melting ice) containing germs from 

 soiling the cap which directly covers the milk. In removing the 

 latter any material on the cap might easily fall into the milk. The 

 parchment paper caps are held in place by a rubber band about the 

 neck of the milk bottle and cost less than one-tenth of a cent 

 when bought in quantity. On them may be printed the day and
