THE SUGAR INDUSTRY 



Experiments with Sugar Pulp 



Speaking of a shipment of sugar cane 

 pulp to Mobile from Cuba last week, the 

 NezL' Orleans Picayune says: "The ship- 

 ment came on the steamer "Trafalgar" and 

 constituttc! 4,127 bales, which was loaded 

 into 25 box cars, forming a special train 

 and sent to Madison, Wis. The statement 

 is not definitely made, but as there is a 

 beet sugar factory at Madison, where the 

 juice of the beets is secured by diffusion, 

 it is presumed that the experiments with 

 this (Iried sugar cane will be carried on 

 there and careful determinations made of 

 what sugar can be extracted.'' 



Asks for Colonists 



Sr. Frederico Sanchez, owner of the 

 Central Lucia, Oriente Province, recently 

 stated tc Secretary of Agriculture Ortiz 

 that he would accept twenty families of 

 those that will be procured in Europe by 

 the immigration agents. 



To these people Sr. Sanchez will give 

 lands to cultivate and work in his sugar 

 mill. 



Sale of a Plantation 



The Occitania sugar plantation at Maca- 

 gua, Matanzas Province, was sold recently 

 by the bondholders under foreclosure pro- 

 ceedings to the owners of the Agnedita 

 plantation in the same place, the Cia Azu- 

 carera Cent. Aguedita, S. A. President, 

 Jose Maria Herrera. 



The Occitania has not been grinding 

 since the 1907 crop, and in the two pre- 

 vious years of 1906 and 1907 the crop to- 

 taled 22,S3S bags and 31,537 bags respect- 

 ively. 



The Aguedita, on the other hand, has 

 been active each year, with a yearly out- 

 put as follows : 



1906 38,724 bags 



1907 45,824 " 



1908 6,066 " 



1909 17,504 " 



1910* 65,000 "

Wax from Sugar-Cane 



]\Iore and more of the residues of in- 

 dustrial processes, that used to be thrown 

 away, are being found to contain some 

 useful substance. In some cases the value 

 of what was originally considered a "by- 

 product" has come to exceed that of the 

 primary product itself. The residues of 

 sugar-refining have now been discovered to 

 contain a valuable waxj' sul)stance, in suf- 

 ficient quantities to warrant its extraction 

 on a commercial scale. Says a writer in 

 the Rcviic Scientifique (Paris) : 



"When a section of sugar-cane is ex- 

 amined under the microscope, it is seen that 

 from the epidermis exude little protuber- 

 ances, straight or curved and disposed per- 

 pendicularly to the surface. These are 

 made of wax, which, with other waxy sub- 

 stances, contained in other parts of the 

 plant, pass into the juice in the process of 

 its extraction. The lime used in almost 

 all refineries carries them away in the re- 

 fuse of the precipitation process, from 

 which the idea of rescuing them has re- 

 cently been broached. 



"For this purpose, the slimy residue is 

 placed in a receptacle where it undergoes 

 a fermentation which destroys the fatty 

 matters without attacking the wax ; the 

 substance is then dried in the sun and 

 afterward in a current of warm air or in 

 a furnace. The dry product is crusht and 

 treated with benzine or carbon disulfid. The 

 wax thus obtained is then refined by being 

 extracted anew with petroleum essence, and 

 then by filtration through clay or animal 

 black. The residue of this extraction may 

 be utilized as a lul)ricant or treated to ob- 

 tain the sugar which it still contains. 



"Cane wax, thus obtained, is white or 

 pale yellow ; it much resembles in appear- 

 ance Carnauba wax, as also in its hard- 

 ness and high melting-point. The dried 

 slimy residues contain 10 to 12 per cent 

 of it, a sufficiently large proportion to jus- 

 tify the industrial treatment of these re- 

 sidues." — Translation made for the Literary 

 Digest. 



There are 40,000 hectares in sugar-cane 

 in Hawaii.
