As to the Propofal at the end of

this Book, to cleanfe fome Rivers and

Harbours of Mud ; it firft occurred

to me many Years (ince, on feeing

the flow and expenlive Method, of

cleanfing the Yarmouth River near

Yarmouth, by means of a large

Wheel fix'd to a Barge, and turned

by Horfes. The Wheel in turning

round, takes up Mud in large Buckets^

which are fixed to it, and difcharge

it into another Barge. A Method
which they are under a neceflity of
ufing in Holland, where the Waters
move with a very flow progreflive
motion : But in Waters which have a
greater velocity, I am perfuaded that
it would be a much more effectual,
and expeditious, and confequently a
cheaper and better way, to cleanfe
away Mud, by much ftirring of it
thus with Horfe-Rakes.

I fhall be very glad if what I have
here offered, fhall prove of any fer-
vice to the Publick, and be confe-
quently acceptable to Your Lordfhipsu

Being with all due Refpeft,
MY LORDS,

Tour Lord/hips
Obedient humble Servant^
