If his work was not obviously stamped with the hallmark of genius, at any rate it was remarkable for its choice of an unusual and unvarying theme. His pictures always represented some well-known street or public place in London, fallen into decay and denuded of its human population, in the place of which there roamed a wild fauna, which, from its wealth of exotic species, must have originally escaped from Zoological Gardens and travelling beast shows. Giraffes Drinking at the Fountain Pools, Trafalgar Square , was one of the most notable and characteristic of his studies, while even more sensational was the gruesome picture of Vultures Attacking Dying Camel in Upper Berkeley Street . There were also photographs of the large canvas on which he had been engaged for some months, and which he was now endeavouring to sell to some enterprising dealer or adventurous amateur. The subject was Hyenas Asleep in Euston Station , a composition that left nothing to be desired in the way of suggesting unfathomed depths of desolation.
