ry 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.

This chart was originally presented as an illustration, Figure 10.
It is shown here rotated from horizontal to vertical for readability.
As in the original, only a partial board is shown; the number of Scows
was at least 8.]
