 thoroughly, with a moist towel, so that all dust, hair 

 and scales may cling to it, then wash hands in water

 will be the one of the stable-milked cows, which will 

 take place in about from twenty to twenty-five hours, 

 whilst the sample from the second lot, the one pro-

 keep sweet for from ten to fifteen hours longer than 

 the first. 



After improving the conditions of milking, we may 

 turn oiir attention to the straining ; and here, it must 

 be confessed with regret, we find, in general, a sorry 

 condition of affairs. By far too many fanners do not
