NIGHT VISIT TO GUNTHORPES CENTRAL FACTORY 73 



tion stage of the juice, the processes of bleaching and 

 purification not having to be carried out so thoroughly 

 for refining crystals as for Demerara crystals. 



The outstanding difference in the treatment of cane- 

 juice which distinguishes all Crystal-sugar factories 

 from Muscovado works, is the method of doing all the 

 boiling in vacuum instead of by steam. 



A few comparative statistics will help you to realize 

 the enormous economic importance of modern sugar- 

 making machinery, such as that with which this central 

 factory is equipped. 



The Gunthorpes Mill can grind 450 tons of cane in 

 a day — a windmill has done a good day's work if it 

 crushes 30 tons. 



Gunthorpes can make 1 ton of sugar from about 

 9 tons of cane — in Muscovado works, from 12 to 17 tons 

 of cane are generally represented by a ton of sugar.

A PEEP AT RIVAL CANE-LANDS 



You will remember that the object of om- whole 

 expedition was merely to get a peep at the Sugar World. 

 But to do the scantest justice to a widespread industry, 

 I must point out that, so far, I have only taken you 

 to a few of the Imperial British lands where cane- 

 sugar is produced. And although the British Dominions 

 play a very active and important part in the pursuit 

 of this particular branch of sugar- production, you must 

 be made clearly to understand and fully to realize 

 that many foreign countries are our much-to-be-
