Speaking of these unaccountable discharges of guns, we are reminded of a case which happened but a few days ago at Willard Park, Paterson, N. J., where the Great American Handicap will be held in April. It was in a match between Captain "Jack" Brewer and Chris. Reinhardt. When the match was about two-thirds finished Brewer killed a bird with the first barrel and without removing the shell from the other barrel he walked from the score, and just as he was about to set down the gun it was discharged, putting the load of shot into the board at his feet. It made slivers fly, as Jack usually shoots a smart load. What the result might have been had the gun been pointed in some other direction we do not care to think about.
In the first place Brewer had no business, as a pigeon shooter of years' experience, to have turned from the score with a shell in his gun. In the second place, the referee should have been more watchful and not allowed anyone to turn or leave the score until both barrels were empty, not even an empty shell should remain.

More on Brewer, who IMHO was a bit of a sociopath
