at least use them for fuel. A plantation of Cassava would 

 thus give food, fodder, and fuel. Now to the manufacture 

 of the flour. The following method was adoped ;- The 

 crude roots were dug out and cleaned superficially and 

 of adhering earth and root-scabs by washing them, and 

 they were then left soaked in water for six to eight hours. 

 This soaking in water rendered decortication quite easy. 

 The roots were taken out one by one from the trough in 

 which they were soaking, a slit made with a knife in the 

 bark, which was then easily peeled out. The core of the 

 root was then made into slices and put in a trough of filtered 

 water. The slices were left soaking in the filtered water 

 for an hour and then pulped with a dhenki. The pulp was 

 tied in a cloth and put under heavy weight. A cheese-press 

 was used for this purpose. The object of putting the cut slices 

 in water and the pulp under weight is to get the little trace 

 of prussic acid which occurs even in sweet Cassava, out. 

 The slight trace of acrid substance in the sweet Cassava 

 produces no disagreeable effect even when the roots are eaten 

 raw, but its presence can be slightly tasted, and it is much 

 pleasanter to get this slightly disagreeable taste out of the 

 pulp before flour is made out of it. 



754. If it desired to make tapioca meal or tapioca as well 

 as Cassava flour out of the pulp, the pulp is put in a cloth and 

 kept stirred half-dipped in a trough or gamlasi filtered water. 

 This helps the farina to go downward, settle at the bottom 

 of the trough and also more of the acrid substance to be 

 washed out of the pulp. After stirring the pulp in the cloth 

 for an hour in one trough, it is to be stirred for a few minutes 

 in another trough of filtered water and then the excess water 

 squeezed out, and the pulp tied in the cloth is to be passed 

 once more through the press and then spread out thin, ex- 

 posed to the sun to allow of its getting dry the same day, if 

 possible. If the crude roots are left in the wash tank over- 

 night, say, from 9 P.M. to 5 A.M. and the decorticating and sli*
