The ''National" Differential 

 Temperature Alarm 



is a big improvement over all other existing thermostats— 



Because — Its sensitiveness and accuracy of action makes its use 

 invaluable to the florist. 



Because — Its mechanism is constructed of the very best material, 

 thus guaranteeing a durable instrument. 



Because — This instrument can be regulated to allow a difference 

 of only two degrees in temperature. 



Because — It is not affected by dampness and can be placed any- 

 where without destroying its accuracy. 



Because - The use of this instrument will give you absolute con- 

 trol over an important feature of your business. 



Because — Its immediate alarm at the cold or hot danger point 

 means protection for you against damage by cold or waste of 

 fuel by excessive heat. 



Because — We guarantee that actual results will be obtained at 



all times. 



Because — it costs only $6.00 f. o. b. St. Louis, including: 50 feet of 

 rubber-covered wire, 2 bells, 2 dry cell batteries, 1 dozen knobs and cleats, 

 and it may save you hundreds of dollars' damage. 



Anyone can put it up. Try one this year— You'll have them in every house next year.
