3. Moveable coolers on tram-ways or rather railways. 



4. An apparatus to empty the coolers and charg-e the 

 turbines. 



5. And lastly turbines which are filled and emptied 

 without being stopped. 



Unfortunately Major Martin's models were on too 

 small a bcale and could not shew the working of the 

 ajiparatus, as if they had been larger. Without enter- 

 ing into technical details on the general working of 

 the system, let us only mention his turbine. 



The plan he proposes may have appeared of doubt- 

 ful practicability — but in theory it is practicable, and 

 betAvepn theory and practice, although there may be 

 difficulties, there is no impossibility. The sugar could 

 be extracted without any feat of shocks which might, 

 at any rate, be guarded against by brushes or by any 

 other means. 



The extractor receiving its motion from a spring 

 screw, may bo stopped at the proper time. Perhaps in- 

 stead of using a scrt-w to take out the sugar which has 

 been turbined. Major Martin had better add curved 

 surfaces contiTiued beyond the basket of the turbine ; 

 the centrifugal force would do the rest. The Judges 

 regretted the absence of larger models and of the Exhi- 

 bitor himself whose verbal explanations would have 

 been most valuable. 



The opportunity here occurs to observe that our Ex- 

 hibitions are unluckily attained with a serious incon- 

 venience resulting from the nature and destination of 

 the place where they are held. 



The Bazar which is lent to us for that purpose by 

 the Municipal Corporation, is the day before the Ex- 

 hibition, hastly cleaned and vacated by its occupants, 

 in order to receive the articles which are sent the next 

 day. These articles, received between 7 and 10, or 11 

 o'clock, are at about 12 o'clock, submitted to the Jud- 

 ges, then to the public and are afterwards, in the eve- 

 ning T'-turned to their respeciive owners, in order that 

 the Bazar may be restored the next morning to those 

 who supply the town. Now all this is done with so 

 much haste and precipitation, that vinfortunately, m
