UNCLE SAM'S BIG FARM 337 



the farm in 1900, $2,979,197,586; in 1910, $4,760,- 

 060,093. The increase of the value in the ten years 

 amounts to 59.8 per cent of all animals. The increase 

 by classes amounts to 1.6 per cent, in cattle; 132.4 per 

 cent, in horses; 167.8 per cent in mules; 127.1 per 

 cent, in asses and burros; 72.1 per cent, in swine; 36.8 

 per cent in sheep; and 89.1 per cent, in goats. For 

 all domestic animals the average increase in value in 

 the ten years was 59.8 per cent. The average value 

 per head for the animals named other than cattle, which 

 has already been given, is as follows: 



1900 1910 



For horses $49.08 105.06 



For mules 60.11 124.80 



For asses and burros 61.71 124.89 



For swine 3.69 6.86 



For sheep 2.77 4.44 



For goats 1.75 2.12 



The comparisons are modified slightly, as in the case 

 of cattle, by the different dates at which the census 

 was taken, namely, June 1st for 1900 and April 15th 

 for 1910. Had both censuses been taken on June first 

 there would probably have been much less decrease in 

 the number of cattle and sheep, a moderate increase 

 in the number of swine, and a somewhat greater in- 

 crease in the number of horses and of mules, than is 

 shown in the table. 



As regards the value of the different classes of do- 

 mestic animals, horses led in the census of 1910, showing 

 43.8 per cent of the total value of all the classes com- 

 bined. On the contrary, in 1900 the value of cattle 

 greatly exceeded that of horses ; but the value of cattle 

 per head increased only slightly during the decade, 

 while that of horses more than doubled. Horses, mules,
