In Table 1 there have not been included a few samples in
which cinders were present. Nor does the table include samples
XXIII-5 or XXIII-6 (5 and 6 miles off Chicago Harbor) which contained, respectively, pieces of ceramic tile and rusty nails.
These are mentioned here as evidences of dumping activity past
or present, but are omitted from the table as being of little
significance to the eutrophication process.
