Pages 1 & 2: 'Thameside, 9 Lower Mall, Hammersmith. Dear Mr Johnston, I hope your visit to town will be soon and that you will keep your promise to look me up here. The view from my studio window is quite worth seeing and photographing, and I suggest that you bring a camera with you when you come, as there is a a wealth of material hereabouts. We might go for a bit of a walk. This murky weather gives everything a touch of the mysterious. Have you seen my "London" book? It has been entirely printed on the "Thameside Press" from plates of my own making. I find in photogravure a very congenial process and one capable of many subtleties. You will be interested in my presses and paraphernalia. It will be interesting to talk over the events that have transpired in the photographic world.'
