This parish of Barking is very large, and by the improvement of lands taken in out of the Thames, and out of the river which runs by the town, the tithes, as the townsmen assured me, are worth above £600 per annum, including, small tithes. _Note_.—This parish has two or three chapels of ease, viz., one at Ilford, and one on the side of Hainault Forest, called New Chapel. Sir Thomas Fanshaw, of an ancient Roman Catholic family, has a very good estate in this parish. A little beyond the town, on the road to Dagenham, stood a great house, ancient, and now almost fallen down, where tradition says the Gunpowder Treason Plot was at first contrived, and that all the first consultations about it were held there. This side of the county is rather rich in land than in inhabitants, occasioned chiefly by the unhealthiness of the air; for these low marsh grounds, which, with all the south side of the county, have been saved out of the River Thames, and out of the sea, where the river is wide enough to be called so, begin here, or rather begin at West Ham, by Stratford, and continue to extend themselves, from hence eastward, growing wider and wider till we come beyond Tilbury, when the flat country lies six, seven, or eight miles broad, and is justly said to be both unhealthy and unpleasant. However, the lands are rich, and, as is observable, it is very good farming in the marshes, because the landlords let good pennyworths, for it being a place where everybody cannot live, those that venture it will have encouragement and indeed it is but reasonable they should. Several little observations I made in this part of the county of Essex. 1. We saw, passing from Barking to Dagenham, the famous breach, made by an inundation of the Thames, which was so great as that it laid near 5,000 acres of land under water, but which after near ten years lying under water, and being several times blown up, has been at last effectually stopped by the application of Captain Perry, the gentleman who, for several years, had been employed in the Czar of Muscovy’s works, at Veronitza, on the River Don. This breach appeared now effectually made up, and they assured us that the new work, where the breach was, is by much esteemed the strongest of all the sea walls in that level.
