"The dwellers on the banks of the Oise and the Seine knew him [Daubigny] well. The ambulant landscape painter was more especially designated by the title of the 'Captain', a rank which vastly flattered him, for by dint of living on the water he had acquired a sailor's roughness and a sailor's pride in good navigation. The boat used by Daubigny was arranged for long voyages; the cooking was done on board; there was a good wine cellar; you drank deep and you worked hard. The sketches accumulated; and when winter was come, Daubigny returned to Paris provisioned with the booty of art and nature, the landscapes which, towards the close of his life, collectors and dealers battled for. How many times I have seen him thus, in his latter days, when his hair had grown white.."
