D. H. Burrell & Co. have put on the market a very good 

 heater, and in Fig. 29 I show it taken apart for cleaning. This is 



claimed to heat up to 

 7,500 Ibs. per hour. 



The Creamery Pack-

 The Root Heater is a 

 new construction of

tomatic heat-regulators 



will be used in connection with all heaters.
