The greatest losses usually follow the turning of stock 

 into fields in the fall, from which the crop has been

 from the stubble is exceedingly dangerous at such a 

 time, and what feed there is in the field may better be 

 wasted than to risk the losses that are sure to follow. 

 Hogs, however, seem to be perfectly immune to this 

 poison and may use such feed without danger. 



There is no known absolute remedy for prussic acid 

 poisoning, unless it be the permanganate of potash 

 drench, and generally the animals are dead before any- 

 thing could be done, as it is one of the most deadly and 

 active poisons known.
