Site for Factory. The first point to be con- 

 sidered when choosing the site is the possibility of 

 a good permanent water supply. We may state 

 here that the supply necessary for pulping Coffee 

 by power is about 800 gallons per hour. On a few 

 favoured estates a good spring of water occurs at 

 a high level. By means of a pipe line, this can be 

 run direct to the machines, obviating the need of a 

 pump. Means must be provided for the storage of 

 the water, so that a large quantity may always be 

 available. The storage can be arranged for either 

 at the factory or at the source. The latter place is 

 preferable, as it will give water under considerable 

 pressure at the factory, and it will not then be 

 necessary to provide large storage tanks for the 

 factory. 



If there is no such source of water supply con- 

 venient, the site for the factory must be near the 

 supply, so that a pump can be used to raise the 

 water to tanks at a level above the machines. Here 

 also a reservoir should be built, so that there may 

 always be a reserve of water to draw on. It is
