POSTAGE RATES ON BOOKS 



On the books listed in this Bulletin, postage is extra in all cases where 

 postpaid price is not given. Under the parcel post regulations it is impos- 

 sible to indicate the postpaid price of those of our publications which 

 weigh more than eight ounces. The cost of transportation of such books 

 is now figured at the pound rate, and depends on the distance in zones 

 from Chicago. As an aid in estimating the carriage charges the weight of 

 each book, wrapped for shipping, is given. With this as a basis, the rate 

 on any book from Chicago to the postal zone in which the purchaser 

 resides may be ascertained from the local post-office, and the amount of 

 postage estimated accordingly. 



In some cases of great distance from Chicago, it is cheaper to ship by 

 express than by parcel post. We take great care to ship by the cheapest 

 method, and, in case of a saving in the expense of transportation, the dif- 

 ference is refunded to the customer. 



Remittances should be made in Chicago or New York exchange; if 

 local check is used, 10 cents must be added for collection.
