On ;the average about one long ton of sugar is produced 

 per acre. e : 



The factories iti Operation have a daily slicing capacity of 

 49,200 tons and those under construction, or, not in opera- 

 tion have an additional capacity of 3,200 tons. The indi- 

 vidual factories can slice from 350 to 3,000 tons per day. 

 The two most common capacities are 1,200 and 600 tons. 

 Many of the smaller factories are constructed so as to per- 

 mit of doubling their capacity at a relatively small cost. 



The factories may be roughly arranged in three groups 

 those of California, of Colorado and neighboring states 

 where irrigation is used, and those of the humid region, of 

 which Michigan and Wisconsin are the most important. 



Climatic Conditions 



Volumes have been written in regard to the climate, soil, 

 cultural and manufacturing conditions best suited to the 

 industry. While it is true that most of the early failures 

 were due to neglect of these conditions, it is also true that 

 there are a number of local conditions that have had much 

 influence in fixing the three present centers of the industry in 

 the United States. 



In general the successful factories here, as well as abroad, 

 are located within 100 miles on either side of a line whose 

 average summer temperature is 70 degrees Fahrenheit. 



The distribution of the rainfall in the humid region is also 

 important, a low rainfall in October and November being de- 

 sirable to permit the ripening arid harvest of the beets.
