Islands — furnished nearly 22 per cent, and the rest, amounting to 
55 per cent, came from foreign countries during 1906-1910. 
The beet-sugar industry in the United States is not localized, 
as is the cane-sugar industry. Beets are grown and beet sugar 
is made in localities more or less scattered, in various regions extend- 
ing all the way from Ohio to California, including on the north 
Minnesota and Montana and at the south Arizona. About two- 
thirds of the beet sugar made in the United States comes from the 
factories of California, Colorado, and Michigan. In 1912, the year 
of highest production up to date, 73 factories were in operation, 
with an average output of 9,500 short tons per factory for the cam- 
paign. The year before, the 66 factories then in operation made an 
average of about 9,000 tons each. The beet-sugar campaign averages 
from 80 to 90 days a year. 
While cane is produced in considerable quantities in the Southern 
States, especially in those bordering the Gulf of Mexico, it is not 
used for manufacture into sugar to any noteworthy extent except in 
Louisiana and a few localities in Texas. Throughout most of the 
cane-producing area sirup, not sugar, is made. Census returns 
indicate that the output of cane sirup in contiguous United States 
increased from 13,000,000 gallons in 1899 to 23,000,000 gallons 
in 1909. Molasses, a by-product of sugar making, increased from 
12,000,000 gallons in 1899 to 25,000,000 gallons 10 years later 
(Table 9). 
All but a small fraction of the domestic cane sugar in contiguous 
United States comes, from the southeastern quarter of Louisiana. 
Production in this State within the past few years has exceeded 
340,000, and even 350,000, short tons annually, showing that the 
industry has been a progressive one, the output in earlier years hav- 
ing been much less. In 1912, however, owing to floods which injured 
cane fields, the Louisiana production dropped to about 154,000 short 
tons, while the number of factories in operation was only 126 as 
compared with 188 in the previous campaign. The length of the 
campaign was also reduced to about 30 da}~s' actual operation in 1912 
as compared with more than twice that time in 1911. A large part 
'of the sugar made in Louisiana factories is shipped to New Orleans, 
most of it reaching that city about the last of December, which is 
practically the end of the sugar-making season. During the past 
five years more than three-fourths of the total receipts of Louisiana 
sugar at^Xew Orleans arrived there before the end of December. 
Data collected by the United States Department of Agriculture 
show that in 1911 about 2,000 pounds of sugar on an average were 
made from an acre of cane in Louisiana. This refers only to cane 
used for sugar and does not include that used for seed, which amounts 
to an average of about 1 acre in a total of 5, nor does it include cane 
used for sirup making. In the same year an acre of beets, in the
