For creameries operating on a large scale, special incubators 

 and other equipment, manufactured and placed on the market, 

 with detailed directions for installation and use by reliable milk 

 products equipment manufacturing firms greatly facilitate the 

 work and enhance uniformity of results. 



First Propagation. Fill a clean and properly scalded quart 

 jar two-thirds full of milk or skim milk. Pasteurize at 180 F. 

 or above and hold for not less than 30 minutes. Time may be 

 saved by heating the milk before the jar is rilled, then fill the jar 

 with the hot milk and set it in hot water at 180 F. for 30 minutes.
