We had with us a chart, showing the position of the wrecks round the English coasts.  There were a considerable number around this headland; but many more up the Bristol Channel, especially at the mouth of the Severn, where the river appears crowded with black dots.  Off Plymouth, long rows of dots show where vessels have gone down.  Between Lundy Island and the Welsh coast they are numerous; while they are equally dense between the Eddystone and Falmouth.  They cluster thickly in the neighbourhood of all the headlands round Cornwall.  Though more sprinkled, they are almost within hail of each other across Saint George's Channel,--from the entrance, to the north of the Isle of Anglesea,--and still thicker at the mouth of the Mersey.  There are not a few off Portland.  Between that and Beachy Head they lie very close; but from Dungeness to the North Foreland they almost touch each other, every part of the Goodwin Sands being covered by them.  All along the shore at the mouth of the Severn they can be counted by dozens; but the sandbanks off Great Yarmouth have proved the destruction of more vessels than the rocks of any other part of the coast.  There is scarcely twenty miles of shore anywhere which could be passed over without those dark spots which show that some vessel has been wrecked.
