 conjecture, continued from its present mouth, at Heysham Point, through green plains, now the Bay of Lancaster, in the direction and to the distance of "Lune Deep," than that it was excavated by the current of Lune, as it exists to-day, after mingling with the waters of Morecambe and Wyre. The course and completeness of Wyre channel from Fleetwood, between the sandbanks called Bernard's Wharf and North Wharf, to its point of junction with the stream from Lancaster, prove satisfactorily that at one time the former river was a tributary of the Lune. Other evidence can be brought forward of the theory we are wishful to establish—that the southern portion of Morecambe Bay, from about Heysham Point, bearing the name of Lancaster Bay, as well as "Shell Wharf" was about the era of the Romans, dry or, at least, marshy land watered by the Wyre and Lune, the latter of which would open on the west coast immediately into the Irish Sea. If the reader refer to a map of Lancashire he will see at once that the smaller bay has many appearances of having been added to the larger one, and that its floor is formed by a continuous line of banks, uncovered each ebb tide and intersected only by the channels of Wyre and Lune. The Land Mark, at Rossall Point, has been removed several times owing to the incursions of the sea, and within the memory of the living generation wide tracts of soil, amounting to more than a quarter of a mile westward, have been swallowed up on that part of the coast, as the strong currents of the rising tides have swept into the bay; and in such manner would the land about the estuary of "Lune Deep," that is the original river of Lune, be washed away. As the encroachments of the sea progressed, the channel of the river would be gradually widened and deepened to the present dimensions of the "Deep"; the stream of Wyre would by degrees be brought more immediately under the tidal influence, and in proportion as the Lune was absorbed into the bay, so would its tributary lose its shallowness and insignificance, and become expanded to a more important and navigable size. About the time that "Lune Deep" had ceased to exist as a river, and become part of the bay, the overcharged banks of the Wyre would have yielded up their super-abundance of waters over the districts now marked by Bernard's Wharf and North Wharf, and subsequently, as the waves continued their incursions, inundations would increase,
