_Aboriginal Chambers near Tilbury._--It is proposed to descend some of
the aboriginal chambers alluded to by Camden, near Tilbury in Essex. In
consequence, however, of Camden having named a wrong parish, later
antiquaries have been puzzled to ascertain their precise whereabouts.
Mr. Crafter, in 1848, after many days' labour, found them out; and a
brief notice of them was given {463} in an article upon "Primæval
Britain" in the _West Kent Almanack for_ 1849. Hasted mentions similar
pits in Crayford Parish, Kent. In Dartford parish is another called "the
Sound Hole," from the echoes, &c., made upon a stone being thrown down.
Mr. S. Laudale intends an examination of it this summer. Tradition
reports that there are three enormous caverns, which communicate with
the central shaft.

How, or what, is the best way of driving the foul air out of those
chambers which are aloof from the central shaft?
