On 23 September 1881 a newspaper reported, 'His first water-colour drawing is Swan Pier and London Bridge from a low point of view, just above the pier - dull sky, Thames reflecting it, dark smoke from boat beside the pier, mist through the arches, and vapour of multitudinous chimneys.' 1 Way & Dennis wrote that the view showed London Bridge, with the old Swan Pier in front, but T. R. Way later stated: `His first new experiment ... was a drawing of London Bridge by afternoon light, done from Old Swan Pier.' 2
