FOWLNESS.

Thus, taking the alluvial surface as a datum line (and its variations
from a true level do not exceed two feet), we have the following
depths to the base of the London Clay :—
A certain amount of doubt attaches to some of these, depending,
as they do, merely on the memory of sinkers who have spent their
lives in such operations, and may easily confound one section with
another.
In conclusion, I would draw attention to the fact that the par-
ticulars I have had the honour to bring before you are only such as
can be advanced on an occasion like the present—the broad
general features of the locality. The precise delineation of details,
the mapping out of the original islands, the determination of the
relative dates of enclosures, the set of the depositing or eroding
currents, past and present, and other matters, demand, and are
worthy of, careful study, and this in an area that most geologists
would hurry past with the sneering remark, "Nothing but alluvium !"
Spotted Redshank near Harwich.—"We have had quite a flight of these
birds in this neighbourhood; several frequented a piece of bentlings at the mouth
of the river Orwell, and a female specimen was shot on the 4th September. I had
previously shot one in the same place on 15th August, 1885, Their call is quite
different from that of the common Redshank, and may be distinguished some
distance off, when, if fairly imitated, the bird will fly towards you.—F. Kerry,
Harwich," in the "Zoologist" for December, 1889.
