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 constracted 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 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.

In the larger house the radiation is 

 only sufficient for 50 degrees in your 

 Indiana climate. If a temperature of 

 60 degrees is desired, three 2-inch pipes 

 should be added to the returns in the 

 larger house. The heater is also fifty 

 per cent larger than is required.
