234 THE SUGAR BEBT. 



straw. Mr. Maumeiie considers that the juice should he 

 left for twenty-four hours before being pumped through 

 the pipes. In this manner the solid portions are soon 

 deposited at the bottom. Another precaution, which 

 we think important, is to thoroughly clean these pipes 

 by means of a rapid circulation of water before and 

 after the juice is to be, or has been, circulated through 

 them. If these points be attended to the above acci- 

 dents are not to be feared. The j-aperies are gener- 

 ally in communication with the central factory by a 

 telegraphic wire, with the assistance of which in a 

 moment's notice the movement of the liquid can be 

 stopped. It might be well to state that air is frequently 

 carried with the juice; this is gotten rid of by an 

 apparatus which is placed over the most elevated 

 portion of the pipe. The first cost of these raperies 

 may be estimated at $6.00 per 1000 lbs. of beets to 

 be pressed. From what has been said, we may 

 conclude that there exist many advantages in the 

 establishing of these raperies when it is necessary to 

 work on a large scale, not, however, from economy in 

 working the beets, as in this case it is more costly to 

 pj-ess the roots to extract the juice than when these 

 operations take place at the factory itself, as the 

 steam generated in a boiler to work the rasp is utilized 

 but once. But these losses are greatly compensated 

 by the transportation, the cost being reduced to 4.5 

 per cent, of what it would otherwise have been, the 

 beets containing but 80 per cent, of their weight in
