There is one legacy of his busy life which seems to have a special interest to those who loved his work and care to know how he did it. For many years he carried in his mind a plan for a new work, which was characteristic of his genius, and would have added a new delight to those he had conferred. He meant some day to write and to illustrate a book which should describe the history of the endless movement of water, from cloud to mountain-top, from the heights to the valleys, from the valleys to the sea, and back to the clouds again. He had made many notes and references, and the scheme was well worked out in its general features. The memoranda which he left are sufficiently full to convey a clear idea of what he proposed; and as one reads them they seem to suggest all the graceful text and the graphic illustration with which his matured skill would have filled them out. While they raise the keenest disappointment in the thought that they never were completed and that American literature and nature-study have missed what they promised, yet they are so full of hints, so stimulating to the imagination, that they seem to belong to that public for which he wrought, and which prizes every thought of his fertile mind. On the fly-leaf of the blank-book in which these notes are entered, with long blanks for the material yet to be written in, he has written the words “Memoranda; Cycle of the Raindrop.” On the next page follow a number of tentative titles: “From the Fountain to the Deep Sea. “The Cycle of the Raindrop. “From the Rain Cloud to the Sea. “A Mission of “A Cycle of “The Emblematic Cycle. Typical of human life. Soul from heaven. Earthly pilgrimage: dross and impurity and final resurrection in mist.” “An Eternal Pilgrimage “A---- Pilgrimage “The Story without an End. Then follows a suggestion for a table of contents. He heads it, _Division of Subject_ “1. The Rain Cloud and the Fountain. ‘Story of a Fountain.’ “2. The Mountain Brook--(Trout Brook) (Trout Stream). “3. The Mountain Lake. The Swamp. “4. The Pastoral Brook. The Pond? “5. The River. “6. The Delta and the Deep Sea.” This is the first and broadest sketch. Upon this ground plan he proceeds to lay out the themes he would treat, evidently having in mind both text and illustrations. Sometimes the note means one, sometimes the other. And the closeness with which the two are associated in his mind is a fine revelation of the manner in which his thought embraced both forms of production in a profound psychological unity. _1. The Rain Cloud and Spring_ The birth of the spring; from perpetual snow on mountain peaks; dew; mist and cloud; storm cloud. Rain Cloud dragging its veil on mountain-top. (See quotation from Ruskin in note-book). Poetic simile of mountain “Light of Asia” (227). Storm on mountain.
