TO MAINTAIN AN EVEN TEMPERATURE IN YOUR GREENHOUSES, USE A 



Foster Pressure Regulator 



With this simple device attached to your steam main just inside the greenhouse the pres- 

 sure on the heating coils will be absolutely constant, anywhere from 1 to 15 pounds (whatever 

 the grower sets the Regulator at), no matter how the pressure on the boilers runs up and down. 



lftii(i weather changes, or the sun heat varies, instead of turning on more pipes, just turn a nut on the 

 Kegulator, and get more steam, or less steam, at once. Made in sizes from %-inch to 10-inch just for this work. 



"The Foster Pressure Hegulators which have been Installed In our greenhouses are Riving 

 perfect satisfaction."— Peter Kelnberg. Chicago. March 16, 1910.
