he heated to almost any temperature desired (short of boiling), 

 by steam and cold water coming in contact, in varying proportions, 

 according to the amount of either which is permitted to flow into 

 the tee. Thus the steam enters the side and the water the top of 

 the tee, both being regulated by valves in the steam and water pipes, 

 and the hot water flows out below. Cold water or steam may be 

 obtained separately also, from the device, which is comparatively- 

 inexpensive. A very convenient bottle-washing machine is shown 

 in the Appendix (p. 328). 



The routine of operating the dairy would be as follows : The 

 empty, returned bottles would be taken from the wagon boxes into 

 the milk room and there rinsed in warm water, in one tub, and then 

 scrubbed with a brush in another tub holding alkali and water, as 

 hot as the hand can bear. The bottles should be next rinsed in 

 clean, hot water, inverted in the racks and placed in the sterilizer, 

 where they are sterilized at 212 F. (as shown by a reliable ther- 

 mometer) (Fig. 35) for an hour. The bottles should remain in- 

 verted until used. 



The milk is brought from the barn in milk pails or cans, as 

 soon as milked, and poured into the Star trap strainer resting in 

 the receiving tank of the Star milk cooler with ice water section, 

 or, better, into the covered cooler described on p. 119). The milk 

 flows from the collecting tank of the cooler into a large can, if
