 made of two 6-foot sashes placed the 

 long way. The side walls are two feet 

 high and the walks dug down below the 

 ground line to give sufficient head room.

 boiler room, with no exposed glass, while 

 the opposite gable end will be exposed 

 and has a wall two feet high of wood, 

 the remainder being glass. In all there 

 are approximately 1,300 square feet of 

 glass. The temperature to be maintained 

 is 50 degrees, with the lowest outside

insures the accurate, automatic steam regulation that will avoid this 

 two-edged loss. It gets full value out of your coal and delivers the 

 even heat so necessary to the proper nurturing of your growing 

 plants. 



Fisher Reducing Valve will not hammer or chatter. Inner valve is 

 semi-balanced and double sealed. Being made of Duramitc, itreduces 

 wire drawing to the minimum. 



It is made in a wide variety of iulet and outlet size combinations, 

 enabliug you to use a smaller sized pipe for high pressure main. 



Most florists are familiar with the Fisher Reducing Valve. For 

 many years it has helped them save coal and grow better plants. 

 You should let it save money for YOU.
