Model of a method for erecting a lighthouse on the Goodwin Sands.
[The difficulties that have attended the erection of a lighthouse on the Goodwin Sands have hitherto been insurmountable, owing to their great depth, and their constant liability to shift. No erection can be considered secure that does not at least rest upon the chalk, and possess gravity or strength in itself sufficient to resist the violent action of the sea: the greatest observed pressure per square foot of surface, exposed to the action of the waves, is 4,335lbs.—S.
