Formerly the city was much injured and rendered unhealthy, by the practice of killing animals for market in the crowded sections. In the summer these slaughtering establishments were perfect pesthouses. Now the slaughtering is done almost entirely at the abattoirs, or slaughter houses, at Communipaw, New Jersey. The buildings used for this purpose are large, and are fitted up with every convenience. The cost of killing is slight, and the butchers are well repaid by having their meat sent to them in excellent condition.
