I had been for some time contemplating the possibility of retiring altogether from business. I had got enough of the world's goods, and was willing to make way for younger men. But I found it difficult to break loose from old associations. Like the retired tallow-chandler, I might wish to go back “on melting days.” I had some correspondence with my old friend David Roberts, Royal Academician, on the subject. He wrote to me on the 2d June 1853, and said:—

“I rejoice to learn, from the healthy tone that breathes throughout your epistle, that you are as happy as every one who knows you wishes you to be, and as prosperous as you deserve. Knowing, also, as I do, your feeling for art and all that tends to raise and dignify man, I most sincerely congratulate you on the prospect of your being able to retire, in the full vigour of manhood, to follow out that sublime pursuit, in comparison with which the painter's art is but a faint glimmering. ‘The Landscape of other worlds’ you alone have sketched for us, and enlightened us on that with which the ancient world but gazed upon and worshipped in the symbol of Astarte, Isis, and Diana. We are matter-of-fact now, and have outlived childhood. What say you of a photograph of those wonderful drawings? It may come to that.”
