The weapons of man, however, are not the only

 out of existence tens of thousands of black game, 

 grouse, and partridge in England and Europe. 

 No less than ten million* wild ducks have died

 Salt Lake from an intestinal trouble caused by 

 the chemical constituents of the water. The dead 

 can be counted in the marshes by the thousand; 

 they drift in great masses upon the lake surface,,
