What does a few- 

 thousand dollars 

 mean to you? 



You do not want to lose a few thousand dol- 

 lars. You are always trying to increase your 

 profits, and guarding against anything that 

 may result in a loss. Yet, if you have no ther- 

 mostat, you are overlooking one of the most 

 important means of protecting your profits. 



Careless employes, and many other causes, permit the 

 temperatures in greenhouses to fall unnoticed and 

 greatly harm or completely destroy large crops.

With the Standard Thermostat on guard day and night it is impossible for the temperature 

 to fall too low without being noticed. As soon as the temperature gets near a point that 

 is not safe the thermostat bell rings its warning, giving ample time to prevent damage. 



Standard Thermostats can be connected so that the bell will ring at the grower's bedside, 

 or any place he may choose. They are strongly made, hermetically sealed, making them 

 safe from water. They are easy to put up, anybody can do it. Complete instructions are 

 supplied with every instrument. 



WHY WAIT? 



Why wait until it is too late? Today your crops may be fine, almost ready for the mar- 

 ket. Will they be in the same good condition tomorrow morning ? Right now you should 

 protect yourself against possible loss. Do not wait until the accident has happened, when 

 only $10.00 or $15.00 will prevent it. Send us your check now for the style you want, or 

 write for a booklet. 



Standard Recording Thermometer 



Growers who have once used Standard Recording Thermometers 

 never want to be without them. Progressive growers who spare 

 no effort in raising the highest grade stock use recording ther- 

 mometers and know the great aid of a complete record of tem- 

 peratures. As in all other businesses, nothing is more important 

 in growing plants than having complete records. With a Stand- 

 ard Recording Thermometer you can know why stock was good 

 or bad, as the case may be, as far as temperatures are concerned ; 

 and the records will be of invaluable assistance in growing the 

 next crop. Your equipment is far from complete if you have no 

 Standard Recording Thermometer.

The actuating element of the Standard Recording Thermometer 



is of lamina metal, which, besides being extremely sensitive to 



temperature changes, is practically indestructible. Record charts are furnished either daily 



or weekly, and the whole mechanism is contained in an attractive metal case fitted with 



lock and key, which insures the record from being tampered with. 



The clock movement is of extremely high grade ; everything about the instrument is up 

 to the highest possible standard of manufacture.
