Excerpt: "The object of the following pages is to re-study the character of Turner's art in the light of his sketch-books and drawings from nature. During Turner's lifetime his rooted objection to part with any of his sketches, studies, or notes often formed the subject of ill-natured comment. Yet we owe it to this peculiarity that the drawings and sketches included in the Turner Bequest at the National Gallery comprise practically the whole of the great landscape painter's work done direct from nature. The collection is, therefore, of very great psychological interest. It shows clearly upon what basis of immediately presentative elements the airy splendour of Turner's richly imaginative art was built: and amongst the twenty odd thousand sheets of drawings in all stages of elaboration, the embryonic forms of most of the painter's masterpieces can be easily traced."
