Sidney Colvin,
Dictionary of National Biography
(1901)
“ In 1876 he took with R. L. Stevenson the canoe trip on the Sambre, Meuse, and Somme, which is the subject of the 'Inland Voyage.' His work in landscape painting, exhibited at the Royal Academy and elsewhere, was interesting and competent; but his incapacity for self-assertion and lack of commercial instinct would probably have hampered his career as an artist, even had his executive powers been greater than they were. ”
