The study of coast scenery is quite as full of changing beauty as the open sea, and it has certain types that belong to it alone. Breakers and surf, and the contrast of land and sea colors and forms, give great variety of subject and problem. In the drawing of rocks the study of character is quite as important, but not so evasive, as the study of wave forms. You must try to give the feeling of weight to them. The mass and immovability add to the charm and character of the water about them.

Subject.—Don't undertake too much expanse on one canvas. Of course there are times when expanse is itself the main theme; but aside from that, too much expanse will make too little of other things which you should study. Whether your canvas be big or little, to get expanse everything in the way of detail and form must be relatively small, otherwise there is no room on the canvas for the expanse. So if you would paint some surf, or a rock and breakers, or a ship, place the main thing in proper proportion to the canvas, and let the expanse take care of itself, making the main thing large enough to study it adequately. If it is too small on the canvas, you cannot do this.

Ships.—The painting of the sea necessarily involves more or less the painting of vessels of different kinds. You may put the ship in so insignificant a relation to the picture that a very vague representation of it will do, but you must have a thorough knowledge of all the details of structure and type if you give any prominence to the ship in your picture.

Detail.—You do not need to put in every rope in a vessel. You do not need to follow out every line in the standing rigging even, in order to paint a ship properly. To do this would miss the spirit of it, and make the thing rigid and lifeless. But ignorance will not take the place of pedantry for all that. Every kind of vessel has its own peculiar structure, its own peculiar proportions, and its own peculiar arrangement of spar and rigging. Whether you are complete or not in the detailing of the masts and rigging, you must know and represent the true character of the craft you are painting. You must take the trouble to know how, why, and when sails are set, and what are the kinds, number, and proportion of them, and their arrangement on any kind of vessel or boat you may paint. There is again only one way to know this. If you are not especially a painter of marines, you may find that the study of some particular vessel in its present condition and relation to surrounding things will serve your turn; but if you go in for the painting of marine pictures generally, you can only get to know vessels by being on and about them at all seasons and places. Your regular marine painter fills dozens and hundreds of sketch-books with pencilled notes of details and positions and accidents and incidents of all sorts and conditions of ships. Ships under full sail and under reefed canvas; ships in a squall and ships in dead calm—he can never have too many of these facts to refer to.

The true marine painter is nine parts a sailor. If he does not take, or has not taken a voyage at sea, at least has passed and does pass a large part of his time among vessels and sailors. He knows them both; his details are facts that he understands. And what he puts in or leaves out of a painting is done with the full knowledge of its relative importance to his picture and to the significance of the ship.

All this sounds like a good deal to undertake; but to the man who loves the water and what sails upon it, it is only following his liking, and any one who does not love all this should content himself with only the most incidental sea painting; for sea pictures are not to be painted from recipes any more than any other thing, and ships particularly cannot be represented without an understanding of them. And after all, you do not have to do all this study at once. If you will only study well each thing that you do, and never paint one vessel or boat without understanding that one; if you will study the one you are doing now, and will do the same every time,—eventually you will have piled up a vast deal of knowledge without having realized how much you were doing.

Color of Water.—You must study the color of water in the large when you paint it. Remember that its color depends on other things than what it is itself. The character of the bottom, whether it be rocky or sandy, and the depth of the water, will affect its color; and to one accustomed to see these things, the picture betrays its truth or falsity at a glance, especially as the character of the wave and the great movement of the whole surface are influenced by the same things.
