comes up in abundance every spring in its first-observed 

 station — a low line of ballast-heaps, deposited, I am 

 assured, before any present inhabitant of Shoreham can

 the shingle, over against Southwick ; and again, on a part, 

 now occupied by a quay, of the landward shore of the river 

 at Kingston."
