422 FARMING FOR LADIES. [chap. xxi. 



if the churning be finished in less than an 

 hour ; and, if it exceed an hour by twenty 

 to thirty minutes, they think it improved both 

 in quantity and quality. 



We have also seen another patent churn, 

 which has only just appeared, made also of 

 metal, and so exactly alike, both in form and 

 machinery, to that which we have just de- 

 scribed, that it might be taken for the same ; 

 the only difference being that the pan in which 

 it works is enclosed from the air, and thus 

 more effectually retains the heat of any warm 

 water which may be necessary to increase the 

 temperature. 



We should, however, observe, that those 

 persons who keep more than one or two cows, 

 ought always to have two churns, of different 

 sizes, for the different quantities of milk pro- 

 duced in summer and winter.
