In order to keep a record of the fleet of scows, which would show the available supply at a glance, a board, 10 by 15 in., and covered with a heavy sheet of ruled paper, was arranged as shown by Fig. 10.  It was divided into 12 vertical columns, the first of which was headed “Scows,” and contained the name or number of each scow in service.  The next four columns denoted loading points, and were headed “Pier No. 72,” “Thirty-third Street, East River,” “Thirty-fifth Street, East River,” and “Long Island City,” respectively; the sixth column was headed “Greenville,” the seventh “Hackensack,” the eighth “Passaic,” and the ninth “Governors Island,” being unloading points, the tenth and eleventh, “Stake Boat” and “Dry Dock,” respectively, while the twelfth was for “Extra pins,” not in use.  To indicate the condition of the scows, small pins with colored heads were used; white indicated empty; blue, working; black, loaded; red, being repaired; and a pearl-colored pin, missing.  Thus a white-headed pin opposite the number 6 in the column headed Pier No. 72 indicated that scow No. 6 was lying at that pier waiting to be placed in position for loading, whereas a black-headed pin at the same point meant that the scow had received its load and was ready to be towed.

BOARD RECORDING LOCATION AND CONDITION OF SCOWS
