THBEE CALIFOEtNIA HOUSES. 



We should be pleased to get infor- 

 mation regarding our new heating sys- 

 tem, on which we expect to pommence 

 work soon. We have three houses, each 

 23x85 feet and twelve feet high to the 

 ridge, with sixteen inches of glass in 

 the sides. The houses run from north 

 to south and are detached, with a shed 

 running their full width at the north 

 end. We are located in central Cali- 

 fornia, where the temperature never 

 falls lower than 16 degrees above zero 

 and there is plenty of sunshine during 

 the winter months. We have a Kroe- 

 schell hot water boiler, nine feet long, 

 thirty-six inches across and containing 

 ten 4-inch flues. It is said to be large 

 enough for good service. We propose to 

 run a 4-inch main, raising this from the 

 top of the boiler to the highest point 

 and then dropping the flows gradually 

 to the farther end of the house, where 

 they would be connected to returns on 

 each side. Would two 2-inch flows over- 

 head, with three 1 14 -inch returns on 

 each side, be suflScient to heat the 

 houses, maintaining a temperature of 

 55 degrees? 

 We wish to connect the feed pipe to 

 return at the boiler, this pipe coming 

 from a supply tank thirty feet high,
