if this was for any reason inconvenient, Marvell signed alone. No
letters, unless in Marvell's writing, are preserved at Hull, which is a

One of these bits of local business related to a patent alleged to have
been granted by the Crown to certain persons, authorising them to erect
and maintain _ballast wharfs_ in the various ports, and to make charges
in respect of them. This was resented by the members for the ports, and

suspended. Marvell, like a true member of Parliament, wishes to get any
little local credit that may be due for such prompt action, and
