* My experience has uniformly been favourable to the sour 
wash (not acetous) both for health and economy ; much less 
grain or meal will suffice; and its fermentation with water 
fixes the saccharine quality, so essential to nutrition. Salt — 
is often given. I never pen my hogs in hot weather. Mr. 
D. G. is on a great scale; and must do it. His sti/] wash 
may require to be sweet ; under the circumstances in which 
his swine are placed. His chopped grain has undergone fer- 
mentation, before distillation ; and I know his intelligence on 
the subject. In summer my hogs chiefly run on clover. Swine 
feeding on clover in the fields, will thrive wonderiully ; when 
those (confined or not) fed on cut clover, will fall away. My 
use of rotten wood, continues to answer every purpose intend- 
ed by its being given. I am much gratified, by the information 
that there are other substances answering, the same end.
