milk, and cause bad flavors. In most of the creameries the 

 exhaust-steam from the engine is used to heat the water for the 

 boiler. This steam is likely to carry with it cylinder-oil, which 

 will impart undesirable flavors to the butter. Some creameries 

 are also using boiler compounds for the removal of scales. 

 These, when subjected to high heat and pressure, are likely 

 to be transmitted to the steam-pipes, and from there with the 

 steam into the milk. The scale and rust of steam-pipes are 

 also likely to be transferred to the milk. 



The right way to heat milk previous to skimming is to make 

 use of one of the special heaters on the market, which heat 

 by the use of steam or hot water indirectly.
