In either of the above cases thegold is brought to the amalgamating machine for amalgamation. Most of the gold-mining establishments are provided with Chilian mills for crushing the ore. Wefurnish a description of it in its simplest form in Fig. 2808, in which form most of these machines areerected. Still, there are some machines of this kind in North Carolina, which work by four or five run-ners or crushers in one trough. 2814.
