_Mount Mill, and the Fortifications of London_ (Vol. ix., p. 174.).--B. R.
A. Y. will find that the name is still applied to an obscure locality in
the parish of St. Luke, situated close to the west end of Seward Street on
the north side. The parliamentary fortifications of London are described in
Maitland's _Hist._, and Mount Mill is noticed in Cromwell's _Clerkenwell_,
pp. 33. 396. This writer supposes that the _Mount_ (long since levelled)
originated in the interment of a great number of persons during the plague
of 1665; but {257} this, I think, is a mistake, for the Mount is mentioned
in a printed broadside which, if I remember rightly, bears an earlier date.
I cannot furnish its title, but it will be found in the British Museum,
with the press-mark 669. f. 8/22. A plan of the city and suburbs, as
fortified by order of the parliament in 1642 and 1643, was engraved by
George Vertue, 1738; and a small plan of the same works appeared in the
_Gentleman's Magazine_ a few years afterwards (1749?).
