At Dairen, in which extensive production is carried on 
upon an intensive system, the hydraulic presses are 
predominant. 
However, in the remote part of Manchuria, small mills 
will quite do, the products being only for local consumption, 
besides owing to the low degree of civilization, the installa 
ion of a modern equipment is sometimes rendered difficult, 
and since the obsolete wedge system entails but a light 
outlay, operated chiefly by manual labour on cheap-priced 
and, it will make the enterprise pay. This accounts for 
the retention of wedge-system mills in the outlandish 
diatriets. 
The mills of the screw system served for the transitory 
period from the native wedge system to the new hydraulic 
aystem. 
(2) BEeaAN REsipuEs COMPARED

We shall now give the quantities of the products 
obtained by the different systems, together with the 
ingredients of the bean residues obtained by the different 
system and their chief uses.
