quantity or value, or both, is mucli larger than 

 the foregoing. In production next to the 

 highest year are found for 1910 the crops of 

 rice, hay, beet sugar and the total for all 

 sugar. In the list of the crops that are next 

 to the highest in value are wheat, oats, barley, 

 tobacco, flaxseed, beet sugar and the total for 

 all sugar. The potato crop was third in order 

 of quantity and the corn crop and the total 

 for all cereals were third in value. Barley 

 and rye were fourth in production and potatoes 

 fourth in value. Fifth in production was 

 wheat and fifth in value rice. 



The average production of the five years 

 preceding 1910 includes the remarkably pro- 

 ductive year 1906 and was generally a period 

 of vigorous production. Notwithstanding the 

 high character of the period, the production of 

 1910 is above the five-year average in the case 

 of corn, oats, rice, rye, buckwheat, beet sugar, 

 the total for all sugar, potatoes, tobacco and 

 wool. In comparison with the average of the 

 preceding five years the value of the crops of 

 this year was greater in the cases of corn, 

 wheat, oats, barley, rye, buckwheat, cotton, 

 beet sugar, the total for all sugar, flaxseed, 

 hay, potatoes, tobacco and hops. 



The value of the farm products of 1910 

 shows both gains and losses in comparison 

 with 1909. A gain of $130,000,000 is made 

 for cotton lint and seed, $30,000,000 for hay 

 and $3,000,000 for barley. A loss was suffered 

 in wheat, amounting to $104,000,000; corn, 

 $98,000,000; oats, $26,000,000; potatoes and 

 wool, $23,000,000 each. . 



The farm value of the cereal crops declined 

 $230,000,000 in 1910 from 1909, and the value 

 of all crops declined $119,000,000. A gain 

 was made, however, in the value of animal 

 products, amounting to $424,000,000. It has 

 been a year of high prices for meat and ani- 

 mals, for poultry and eggs and for milk and 

 butter, and for these reasons the total value of 

 all farm products increased in 1910 $304,000,- 

 000 above the estimate for 1909.
