milk is poured in it washes through any sediment that may ha\e been 

 caught from the previous one. At no time is the small sediment caught. 

 Now, what is the best strainer? We have on the market strainers with 

 certain filtering attachments and after the milk passes through it is almost 

 pure. For those who do not care to go to the expense of such a strainer 

 I would strongly recommend the use of three or four thicknesses of cheese 

 cloth or one layer of flannel or good linen. These are tied in the form of 

 a bag over the ordinary strainer or on a framew^ork of w'ood. The cloths 

 should be washed and boiled immediateh after use and if inclined to smell 

 should be discarded. 



NECESSITY FOR STRAINING. 



Fig. I is a piece of cheese cloth before use and Figs. 2 and 3 are discs through 

 which 60 and 30 gallons of milk respectively have passed. It will be seen that the 

 last is very much the dirtiest. 



When the milk is strained the next matter is the keeping. There is no 

 room for doubt but what the best ^method of keeping milk in a soimd 

 condition is that of running it over a cooler various kinds of which are to 

 be found on the market. Not only does the cooling take place rapidly but 

 the milk is aerated thus driving out obnoxious gases to a considerable 

 extent. The ad\-antage of quick cooling is ob\-ious, every one knowdng 

 that the longer milk is kept at a high temperature the quicker it will sour 

 and vice versa. It is necessary, however, that this cooling prcx:ess must 

 be conducted in an atmosphere as free from dust as possible or the milk 

 will take up a considerable amount of impurities while exposed in thin 

 layers. As alreadv seen the conditions may be made favorable for the 

 production of bitter flavor. In addition to cooling the evening's milk it 

 has been found that by treating the morning's milk likewise a larger per- 

 centage of cheese can be obtained. The matter of water supply is of vast 

 importance. A dairyman of my acquaintance got over the diflicultv bv
