196 AGRICULTURE OF MAINE, 



3.685,789 



From the above it would seem that in the nine states and 

 District of Columbia the number of dairy cows has decreased 

 from 1900 to 1910 and the decrease in the aggregate is 83,152, 

 and there has been an increase in the thirty-nine states and two 

 territories, as above set forth, in the aggregate of 3,685,789, 

 showing a total increase of 3,602,637 cows in the United States 

 from 1900 to 1910. 



The amount of butter manufactured in the United States, as 

 shown by the census of 1900 to 1910, is as follows: 



1900 1910 Increase 



1,491,752,602 i>6i9,4i 5,263 127,662,661 lbs. 



From computations made, I find that in the year 1850 

 there was one dairy cow to 3.63 persons, and that there were 

 13.51 pounds of butter made for each person. In i860 there 

 were 3.66 persons to one dairy cow, and there were 14.61 

 pounds of butter made per capita. In 1870 there were 4.31 

 persons per dairy cow and there were 13.33 pounds of butter 

 made per capita. In 1880 there were 4.03 persons to one dairy 

 cow, and there were 16.08 pounds of butter made per capita. 

 In 1890 there were 3.81 persons to one dairy cow, and there 

 were made 19. 11 pounds of butter per capita. In 1900 there 

 were 4.45 persons to one dairy cow, and there were made 19.55 

 pounds of butter per capita. In 1910 there were 4.45 persons 

 to one dairy cow, and there were made 17.67 pounds of butter 

 per capita. 



Thus it would seem that, while the population has increased 

 since 1850 from 3.63 persons to 4.45 persons per dairy cow, 

 the production of butter has increased from 13.51 pounds to 

 17.67 pounds per capita. 



Thus, while the population has gained on the dairy cow, the 

 production per capita has also increased.
