AMERICAN FORESTRY'S ADVERTISERS 





"The Watch of Railroad Accuracy" 



IT is policy to buy a good watch. The 

 owner of a Hamilton is practically 

 insured against needing a new watch, 

 or against having a watch that is always in 

 need of repairs. 



When you buy a Hamilton, you buy the 

 accurate, durable watch that will tell you 

 true time year after year. 



PRICES OF HAMILTONS: The lowest-priced 

 Hamilton is a movement alone for S12.25 ($13.00 

 in Canada). The highest-priced Hamilton is our 

 Masterpiece at $150.00 in 18 k. heavy gold case. 

 Other Hamiltons at $15.00. $25.00. $28.00. $40.00. 

 $55.00. $80.00, $110.00. etc. All have Hamilton 

 Accuracy, Beauty, and Durability. 



Write for the Hamilton Watch Book 

 "The Timekeeper" 



It's an interesting book on watches. It pictures and 

 intimately describes the various Hamilton models for 

 men and women.
