INTRODUCTION 
In the States bordering the Gulf of Mexico sugar cane is an im- 
| portant crop. Except in Louisiana, which has been a sugar-pro- 
ducing State since colonial days, the production of sugar cane is 
so scattering, however, that it has not been generally profitable 
for cane growers to engage in sugar manufacture. Sirup, rather 
than sugar and molasses, is the principal product made from 
a cane in Florida, Georgia, Wes Mississippi, and Texas.? 
| a le 1 shows the production of sugar-cane sirup since 1899 by 
States. 
1 Recognition is given to the various contributors under the chapter headings. ; 
* Under favorable conditions Louisiana produces 250,000 to 300,000 tons of cane sugar yearly, Texas pro- 
duces 2,000 to 3,000 tons of sugar yearly, and recently Florida has entered into sugar production. 
Notre.—The purpose of this bulletin is to describe the manufacture of sugar-cane sirup in a comprehensive 
| Manner and in this way to assemble existing knowledge of the subject in one publication. It is largely a 
compilation of data from various sources, some of which have been published in technical bulletins and 
journals. Much new material, such as cost data, descriptions of mcedel plants and apparatus, supplemented 
by sketches, and a comparison of the different methods of manufacture, is included,
