THE BLACKWATER ESTUARY. 115 water at the jetty end, enabling steamboats to land passengers there at all times of the tide. When the channel receded, the sand accumulated above the outlet of the sewer on the beach to the extent of about ten feet. This is being gradually removed as the channel advances, and, as stated, it is expected that the cause of the nuisance complained of at Silloth since the outlet of the sewer was filled up, will soon exist no longer." In this last case we have a change for the better, but what may be the nature and date of the next alterations in the channel, no one can foretell. Any purchaser of the Ordnance maps of North Cum- berland and South Dumfries, which were executed at slightly different dates, may ascertain for himself the nature and amount of these shiftings on the Solway. Those on the Blackwater Estuary have probably been less both in amount and in frequency, but a glance at the geological map of the district suffices to show that very con- siderable alterations must have occurred from time to time—altera- tions that would have made the prolonged existence of a port lower down the estuary an extremely improbable event. Thus it is evident that at one time the channel was south, instead of north, of Northey Island; while at another period it was north, instead of south, of Osea Island, and probably, at a third, its course was south of Ramsey. But old maps give no trustworthy information about matters of this kind, and the non-existence of any ports below Maldon prevents us from getting any glimpse of the date and nature of past changes such as we were able to obtain in the case of Skinburness. Thus Maldon, from its commanding site, copious water supply, and permanent closeness to the channel of the estuary, must always have been the one good position for a port on the Blackwater, its advantages being all such as must have seemed much more striking ten or twenty centuries ago than they now do. In short, in the site of Maldon, as in that of ancient London, we have the one position in a district which must have always been occupied as hill, fort, or town, from the very earliest period. We must consequently remember that the real antiquity of such a town can never be measured by appeal to Saxon charters or Roman remains, which belong to a comparatively modern period in its history. The Hatching of Cygnets.—Some correspondence has recently taken place in the "Standard" newspaper as to the number of cygnets which may be hatched in one brood, from which it appears that eight or nine, or even more, are not uncommon events. Mr. John Webb, writing from Dunmow, on June 8th, says, "that a pair of swans, belonging to Lady Brooke, of Easton Lodge, near Dunmow, have this year hatched off nine cygnets, all of which are fine birds and are doing well. This is the largest brood I have ever seen."
