MAIZE GRAIN AS FOOD 695 



"5- It gives by-products that are easily sold and realize CHAP, 

 as much as, and even more than, the sugar. XIV. 



" 6. The cost of manufacturing this sugar is much less than 

 in the case of either sugar beet or sugar cane. 



"7. This sugar can be produced in unlimited quantities, it 

 being possible to supply the whole demand of the United 

 States within a few years. 



" 8. Although the operations of manufacture are distinct, 

 the machinery does not essentially differ from that used for 

 cane sugar. 



" 9- The whole of the residue (after extraction of sap from 

 stalks) can, at a low cost, be converted into a pulp for paper 

 or into cellulose, which can be used for the manufacture of 

 smokeless powder, celluloid, collodion, etc., at a lower cost 

 than when produced from cotton. 



"10. The green ears are easily sold as maizena, gelatine, 

 or even as ensilage or cattle food. ' 



"n. The combination of the manufacture of the sugar 

 with that of the various by-products will keep the staff and 

 the machinery of the factory busy during the whole year, 

 instead of being at a standstill for a greater part of the year. 



" 12. The cultivation of maize for this purpose will give 

 higher profits than if the crop were disposed of in any other 

 way, and will therefore be to the advantage of all maize-grow- 

 ing countries." 



Owing to the wide publicity given to the claims of Messrs. 

 Kerr and Stewart by the press of many parts of the world, it 

 seems desirable to refer to the subject, if only to bring this 

 method of treatment to the attention of those in a position to 

 give it a thorough test. To quote the editor of the Union 

 Agricultural Journal : — 



" The production of sugar, starch, and other by-products 

 from maize is by no means new, but whether the very sanguine 

 estimates outlined by our contributors will be realized on an 

 industrial basis has yet, we understand, to be proven. How- 

 ever, the subject is of such importance to this country that 

 further inquiries are being set on foot. ... It has always to 

 be remembered, however, that to set such an industry firmly 

 on its feet in a country like South Africa, with its peculiar 

 labour conditions, would call for the greatest care and fore- 

 thought, as well as much capital and organizing ability. The 

 sugar-cane industry of Natal is the nearest approach to any-
