brook behind and the ceaseless song of the grasshopper among the weeds in front. A tired bumblebee hums past, rolls lazily over a clover blossom at your feet, and has his midday lunch. Under the maples near the river's bend stand a group of horses, their heads touching. In the brook below are the patient cattle, with patches of sunlight gilding and bronzing their backs and sides. Every now and then a breath of cool air starts out from some shaded retreat, plays around your forehead, and passes on. All nature rests. It is her noontime.

But you work on: an enthusiasm has taken possession of you; the paints mix too slowly; you use your thumb, smearing and blending with a bit of rag—anything for the effect. One moment you are glued to your seat, your eyes riveted on your canvas; the next, you are up and backing away, taking it in as a whole, then pouncing down upon it quickly, belaboring it with your brush. Soon the trees take shape; the sky forms become definite; the meadow lies flat and loses itself in the fringe of willows.

When all of this begins to grow upon your once blank canvas, and some lucky pat matches the exact tone of blue-gray haze or shimmer of leaf, or some accidental blending of color delights you with its truth, a tingling goes down your backbone, and a rush surges through your veins that stirs you as nothing else in your whole life will ever do. The reaction comes the next day when, in the cold light of your studio, you see how far short you have come and how crude and false is your best touch compared with the glory of the landscape in your mind and heart. But the thrill that it gave you will linger forever!

Or come with me to Constantinople and let us study its palaces and mosques, its marvellous stuffs, its romantic history, its religions—most profound and impressive—its commerce, industries, and customs. Come to revel in color; to sit for hours, following with reverent pencil the details of an architecture unrivalled on the globe; to watch the sun scale the hills of Scutari and shatter its lances against the fairy minarets of Stamboul; to catch the swing and plash of the rowers rounding their caiques by the bridge of Galata; to wander through bazaar and market, dotting down splashes of robe, turban, and sash; to rest for hours in cool tiled mosques, which in their very decay are sublime; to study a people whose rags are symphonies of color, and whose traditions and records breathe the sweetest poems of modern times.

And then, when we have caught our breath, let us wander into any one of the patios along the Golden Horn, and feast our eyes on columns of verd-antique, supporting arches light as rainbows, framing the patio of the Pigeon Mosque, the loveliest of all the patios I know, and let us run our eyes around that Moorish square. The sun blazes down on glistening marbles; gnarled old cedars twist themselves upward against the sky; flocks of pigeons whirl and swoop and fall in showers on cornice, roof, and dome; tall minarets like shafts of light shoot up into the blue. Scattered over the uneven pavement, patched with strips and squares of shadows, lounge groups of priests in bewildering robes of mauve, corn-yellow, white, and sea-green; while back beneath the cool arches bunches of natives listlessly pursue their several avocations.

It is a sight that brings the blood with a rush to one's cheek. That swarthy Mussulman at his little square table mending seals; that fellow next him selling herbs, sprawled out on the marble floor, too lazy to crawl away from the slant of sunshine slipping through the ragged awning; that young Turk in frayed and soiled embroidered jacket, holding up strings of beads to the priests passing in and out—is not this the East, the land of our dreams? And the old public scribe with the gray beard and white turban, writing letters, the motionless veiled figures squatting around him—is he not Baba Mustapha? and the soft-eyed girl whispering into his ear none other than Morgiana, fair as the meridian sun?

So, too, in my beloved Venice, where many years ago I camped out by the side of a canal—the Rio Giuseppe—all of it, from the red wall, where the sailors land, to the lagoon, where the tower of Castello is ready to topple into the sea.

Not much of a canal—not much of a painting ground, really, to the masters who have gone before and are still at work, but a truly lovable, lovely, and most enchanting possession to me their humble disciple. Once you get into it you never want to get out, and once out you are miserable until you get back again. On one bank stretches a row of rookeries—a maze of hanging clothes, fish-nets, balconies hooded by awnings and topped by nondescript chimneys of all sizes and patterns, with here and there a dab of vermilion and light red, the whole brilliant against a china-blue sky. On the other is the long brick wall of the garden—soggy, begrimed, streaked with moss and lichen in bands of black-green and yellow ochre, over which mass and sway the great sycamores that Ziem loved, their lower branches interwoven with cinnobar cedars gleaming in spots where the prying sun drips gold.

Only wide enough for a barca and two gondolas to pass—this canal of mine; only deep enough to let a wine barge slip through; so narrow you must go all the way back to the lagoon if you would turn your gondola; so short you can row through it in five minutes; every inch of its water-surface part of everything about it, so clear are the reflections; full of moods, whims, and fancies, this wave space—one moment in a broad laugh coquetting with a bit of blue sky peeping from behind a cloud, its cheeks dimpled with sly undercurrents, the next swept by flurries of little winds, soft as the breath of a child on a mirror; then, when aroused by a passing boat, breaking out into ribbons of color—swirls of twisted doorways, flags, awnings, flower-laden balconies, black-shawled Venetian beauties all upside down, interwoven with strips of turquoise sky and green waters—a bewildering, intoxicating jumble of tatters and tangles, maddening in detail, brilliant in color, harmonious in tone: the whole scintillating with a picturesqueness beyond the ken or brush of any painter living or dead.

These are some of the joys of the painter whose north light is the sky, whose studio door is never shut, and who often works surrounded by envious throngs, that treat him with such marked reverence that they whisper one to another for fear of disturbing him.

And now for a few practical hints born of these experiences; and in giving them to you, remember that no man is more keenly conscious of his limitations than the speaker. My own system of work, all of which will be explained to you in subsequent talks, one on water-color and the other on charcoal, is, I am aware, peculiar, and has many drawbacks and many shortcomings. I make bold to give these to you because of my fifty years' experience in outdoor sketching, and because in so doing I may encourage some one among you to begin where I have left off and do better. The requirements are thoughtful and well-studied selection before your brush touches your canvas; a correct knowledge of composition; a definite grasp of the problem of light and dark, or, in other words, mass; a free, sure, and untrammelled rapidity of execution; and, last and by no means least, a realization of what I shall express in one short compact sentence, that it takes two men to paint an outdoor picture: one to do the work and the other to kill him when he has done enough.
