THE CUBA REVIEW 



boiler was thoroughly washed out with water from a hose at high pressure. The boiler 

 was then closed, filled with clean water and steam raised, and put into commission again. 

 A repetition of this at every week-end for a few weeks will thoroughly clean the dirtiest 

 boiler. 



In handling caustic potash the utmost care must be used; it is truly caustic, and if a 

 small portion splashes in one's face or eyes it w^ill cause serious trouble. The same 

 is true of the hands. For a very hard scale an acid purger should be used, as lime is 

 alkaline and its antidote is an acid. Probably someone may exclaim loudly against 

 using an acid purger, arguing that it will destroy the boiler. It is just liere that trouble 

 is likely to ensue in the hands of an inexperienced person. In the first place, an acid 

 purger is largely diluted with water, and it attacks the scale first, having the greatest 

 affinity for it. After that it would attack the boiler plates if allowed to remain in the 

 boiler, but there can be no after effects of this character from a boiler purger, because 

 it is no longer in the boiler when the scale is removed, the boiler cleaned out by hand, 

 washed with a hose, filled up and blown out again before steam is raised. Of the two 

 evils, it is best to choose the least, and in this case the use of a strong boiler purge is 

 less than the injury and loss of fuel caused by scale. — John Green in Pozver. 



Output of Plantations 



It is stated that two sugar centrals in 

 Matanzas Province, "Dos Rosas" and 

 "Preciosa", have been bought by an Amer- 

 ican company for $S0O,0O0. The two 

 estates are near Cardenas and the new 

 owners propose to merge the two planta- 

 tions into one large central. The former 

 ownership was Cuban. Their output has 

 been ranging between 2.j,000 and 35,000 

 bags each annuallv. 



The Santa Gertrudis in Matanzas Prov- 

 ince has completed its grinding with a 

 yield of 1.39,000 bags. With extension to 

 its fields the estate expects a very much 

 larger yield from the next crop. 



The sugar plantation Preston at Nipe 

 Bay finished grinding August 1st with a 

 yield of 267,801 sacks.

EXACTLY how much juice j ou extract from every ton of caneV 

 >'our present system of determining extraction is iiifalliljle or does it not 

 incorrect results at times? Are your i-olls in such condition that you 

 can extract the maximum amount of juice? 

 H If the cane has dried up ami is of poor 

 quality, wouldn't an ahsolutely correct rec- 

 ord of extraction indicate this and make the 

 remedy possible? 



tl Wouldn't it help you to know exactly the 

 amount of juice sent to ^he sugar house? 

 H THE RICHAUDSOX AUTOMATIC JUICE 

 SCALE will register the actual amount con- 

 tinuously. 



r Trv the new method of WEIGHT as dis- 

 tinct' from MEASUREMENT. You weigh 

 your raw material or cane — You weigh your 

 Product, that is the sugar. 

 H Why not weigh the juice? Measurement 

 is merely approximate — weight is EXACT- 

 NESS.
