this a simple piece of light flannel fixed over the can with 

 a deep sag in the middle by using four clothes pins on the 

 edge of the can. If this is done, and if the milker will take 

 the trouble to change or rinse it out at once when there shows 

 any unusual amount of sediment, then all has been done 

 that can be done under ordinary circumstances. Of the hun- 

 dreds of various strainers, I illustrate only one, introduced 



by Mr. John Boyd (Chicago) in Fig. 

 9 which explains itself. This re- 

 duces the danger of washing the 

 coarse dirt to a minimum as the 

 milk will not be forced through it 

 from above, and if the funnel tube 

 were made with a tee and cap so 

 as to be easier to clean, it would 

 be a great improvement. The milk 

 enters through the outside funnel 

 and rises up through the inner one 

 (over which is fixed a piece of flan- 

 nel with a ring), and overflows into 

 the can provided with a gate valve. 



I a i so chiefly. as a curiosity illustrate one of the latest 

 German strainers, the "Josef Fliegel," in Fig. 80. This

shows how far they go in their attempts in straining. It ex- 

 plains itself, being filled with gravel, which, s of course, must 

 be washed and sterilized every day.
