THE ESSEX FIELD CLUB. 209 before the Royal Commission, 'that whatever pollutions there may be, and they are not many, they are all oxidised by the natural forces before reaching the East London intake or that of the New River to which I have before referred.' " Our attention was arrested by a most abominable odour just below Ware Lock, and at once came questions to Major Flower as to its cause. Could he do otherwise than admit that the cause was the Hertford sewage discharge into the famous "Manifold Ditch" and refer the Club to pp. 20 and 21 of "The River Lee up to Date" for explanation ? He did more ; he explained a scheme of his own for intercepting this abomination and taking it down below Ware Tumbling Bay, a point which he subsequently pointed out, and there filtering the effluent through earth on a sufficient area of land. The only question seemed to be, "Who is to pay for it ?" It was interesting, as passing along the river through Ware, to note the dry mouths of the disused sewers which conveyed all the filth of the town into the Lea, and other indications of abandoned sources of pollution. We noted also "Ware Priory," the pretty home of Mr. Walters, who greeted us as we passed. The Priory, relics of which remain, belonged to a body of Benedictines, who were subordinate to the Abbey of St. Ebrulf, at Utica in Normandy. About a mile below Ware was noticed the junction of another tributary, the Ash river. Arriving at Stanstead St. Margaret's, a halt was made, for, whether it was the odours of the Manifold Ditch, or otherwise, "all hands "were ravenous—some suggested "breaking bulk" of ample provision provided for "afternoon tea ; how- ever, this was "barred,"—and some of the more agile of the passengers leaped ashore as a foraging party, soon returning with an ample supply of scones, biscuits, fruit, and other creature comforts, sufficient to allay the cravings of hunger, for our halt for lunch (ordered at 2) was not likely to be attained before 3 p.m. We were late, but no one wished to hurry, and with such lovely weather and pleasant scenery and surroundings, who cared ? We soon arrived at the Rye House, famous as the place where the plot against King Charles II.'s life was hatched. The Castle is reputed to have been built in 1440. Between Rye House and the junction of the Stort, great interest was shown in the large quantity of the Yellow Mimulus (Mimulus luteus, Willd.), which was growing on the Herts bank of the river. It was apparently quite wild, and we were told that it had been naturalised there for years. The sewage of Ware is carried down to this place and disposed of on an area of land, the sub-soil being the drift gravel of the valley. We next reach Fieldes Weir, a point of extreme importance, for here is the junction of the River Stort with the Lea, and the volume of water passing down the Lea is gauged. The party landed to examine the process of gauging the flow of water, which was explained by Major Flower. The River Stort, from Bishop's Stortford to Harlow, was traversed by the Club on July 18th, 1888 (see Essex Naturalist, vol. ii., pp. 224-227). At this point also the rainfall is measured by one of Mr. Symons' gauges. This was an object of much interest on the part of one distinguished member, who promised us a few words on the subject at a later period.
