272 THE LURE OF THE LAND 



estimated quantity of milk produced was 7,265,804,304 

 gallons. The average amount per cow for 1910 was 

 362 gallons and for 1900, 424 gallons. The average 

 value per cow of the milk produced in 1900 was $27.56, 

 and in 1910, $31.82. These values per cow, however, 

 do not include the amount of milk and other dairy 

 products consumed on the farm. 



The Director of the Census, in discussing the data, 

 calls attention to the fact that while the figures appar- 

 ently show a larger production per cow in 1900 than 

 in 1910, this does not warrant the belief that there has 

 been an actual decrease in the average production of 

 milk per dairy cow. The figures for 1910 are believed 

 to be more accurate than those for 1900, for in these 

 latter is included a large element of estimations. 



In regard to the quantity of butter, is included not 

 only the butter made on farms, but also in factories. 

 The totals for the United States for the census years 

 1900 and 1910 are as follows: 1900, 1,491,752,602 

 pounds; 1910, 1,619,415,263 pounds an increase of 

 8.6 per cent, in the total amount of butter made as com- 

 pared to an increase of 21 per cent, in the population. 

 The quantity of cheese produced, both on farms and in 

 factories, for the two census years is as follows: 1900, 

 298,314,642 pounds; 1910, 320,532,181 pounds an 

 increase of 7.4 per cent. Since the data summarized 

 above have been collected a phenomenal increase in the 

 value of dairy cows has taken place. Good grade cows 

 of the leading types, viz., Holstein, Jersey, and Guern- 

 sey, sell at auction at from $75 to $100, while reg- 

 istered animals cost very much more. The movement 

 to exterminate tuberculosis in milch cows is gathering 

 momentum and I hope will soon be completely success- 

 ful. Various estimates of the number of tuberculous
