Just opposite St. Mark’s College, Chelsea, is a narrow thoroughfare called Lot’s Road, leading to a creek that separates the Borough from Fulham. Tradition says that the locality was formerly known as “The Lots” (about four acres in extent), and was granted to a Sir Arthur Gorges by the lord of the manor, in lieu of certain rights over land which he gave up for the formation of the Kensington Canal; but incredulous old folk dismissed this tradition with contempt, and maintained that there was a Chelsea personage named Lot, very distantly related to the patriarch’s nephew, who pitched his tent in the fertile Jordan Valley, and that the dismal Chelsea wastes so much resembled the desolateness of the fatal plains, that diligent search therein might even result in the discovery of the Pillar of Salt, brought over to this country at some remote period by a pious descendant! But whoever, or whatever, the name Lot may represent, it is now associated with one of the greatest electrical undertakings of the age--the huge generating station of the Underground Electric Railway Company of London, Limited, who, as at present arranged, will supply the District and other railways with power. At the bottom of Lot’s Road, and at a point on the Middlesex bank of Battersea Reach, facing the ugly parish church of St. Mary, is the mouth of Chelsea Creek, filled twice a day by the muddy waters of the Thames, and here the Electrical Works are being erected. They are in sight of an obscure cottage in Cheyne Walk where the painter Turner lived in concealment, and where he died. The building, with its four great chimney-shafts, is unæsthetic to a degree, and Turner would probably have thought it ruined his favourite landscape. But it represents something more valuable than æsthetic effect. When Matthew Doulton, in the infancy of steam, took the Russian Prince Potemkin round the works at Soho, Manchester, the distinguished visitor inquired, “What do you sell here?” “We make and sell here,” replied James Watts’ partner, “that which all the world wants--_Power_.” And this, on a scale undreamt of by the famous engineer, is what the Underground Electric Railway Company of London will produce, in view of the river scenery so much admired by the chief of impressionists, and which he never wearied of depicting. This temple of electric force will be the largest in the Old World. In New York, the Manhattan and the Metropolitan companies both have power stations slightly smaller. The Rapid Transit Commission have projected one that will be bigger, while the Waterside station of the Edison Illuminating Company (partially completed) is on a still larger scale. It has, however, been stated that the biggest power scheme on earth will be at Massena, on the St. Lawrence River, Canada, where there will be fifteen Westinghouse machines, equal to a total of 75,000 kilowatts.
