THE HOME 



water can be kept at almost any desired degree 

 of temperature by the adjustment of the drafts 

 of the heater. An even, summer-like heat is 

 furnished in which all kinds of plants flourish. 

 Hot-water heat is preferable to steam for small 

 houses because of its economy. In the use 

 of steam it is necessary to raise the water to a 

 certain temperature before any heat is given 

 off in the pipes upon which the greenhouse 

 depends for warmth ; in other words, the water 

 must boil before there is any heat in the pipes. 

 To keep up circulation, the fire must be kept 

 burning briskly. Let it die down, and your 

 heat supply is cut off. 



But with hot-water heating circulation be- 

 gins in the pipes as soon as the water becomes 

 warm, and it continues as long as there is any 

 fire. It will readily be seen, therefore, that 

 for mild weather hot- water heating is far supe- 

 rior to steam heating, while all that one has to 

 do to obtain heat enough from it to meet the 

 demands of cold weather is to open the drafts 

 and bring about more energetic combustion. 

 The management of a hot-water heater is so 

 simple that a child can soon learn to operate it. 



Quite satisfactory substitutes for a real 

 greenhouse can be made by enclosing veran-
