It is indispensably necessary that fuel of all kinds should be 

 kept perfectly dry until required for use, as most kinds absorb 

 moisture rapidly and consequently consume much time when 

 burning, converting this moisture into vapor, which carries the 

 heat up the flues instead of disseminating it through the apart- 

 ment. P- 



MILCH COWS. 



BY S. TAN WVCK. 



We have been requested of late by many gentlemen members 

 of the American Institute, and Farmer's Club attached to it, and 

 others, to furnish a table or list for the next tratuacliovs of the 

 be>: A liencan and English milch cows within the last fifty years 

 known. These to be collected from the best records of the two 

 coun'ries. We have endeavored to comply with the request as 

 well as we were able, such lists have been given at various peri- 

 ods as the cows made their appearance, and must be seaiclied for 

 in various volumes that treat on the subject, to ascertain some 

 particulars of their history and qualities. We believe it was 

 me nt to have this information condensed in as small a compass 

 as possible, that it might be embraced by the mind at once with- 

 out much time spent in perusing the article itself, or search in 

 many volumes f^r the fucts they contain. We have also given 

 the average produce in milk, butter and cheese, of the best farm 

 dairies of the two countries.
