“Details in the picture must be elaborated only enough fully to reproduce the impression. When more is done the impression is weakened and lost, and we see simply an array of external things which may be very cleverly painted and may look very real, but which do not make an artistic painting. The effort and the difficulty of an artist is to combine the two; namely, to make the thought clear and to preserve the unity of impression. Meissonier always makes his thought clear; he is most painstaking with details, but he sometimes loses in sentiment. Corot, on the contrary, is to some minds lacking in objective force. He tried for years to get more objective force, but he found that what he gained in that respect he lost in sentiment.”

This is Inness’s own statement of the case and it enables us to understand why many of his later canvases were vague, indefinite, often vapory. He was seeking to give a sentiment or feeling rather than topographical facts. When the facts looked too weak, he tried to strengthen them here and there by bringing out notes and tones a little sharper with the result of making them look hard or too protruding. After several passings back and forth from strength to weakness, from sentiment to fact, the canvas began to show a kneaded and thumbed appearance. Its freshness was gone and its surface looked tortured and “bready.” He was hardly ever free from this attempt to balance between two stools. It is a plague that bothers all painters, and no doubt many of them would agree with Inness in saying:

“If a painter could unite Meissonier’s careful reproduction of details with Corot’s inspirational power, he would be the very god of art.”

But Inness was much nearer to Corot than to Meissonier. He loved sentiment more than clever technique, and perhaps as a result left many “swampy” canvases behind him. His studio was filled with them. He used to take them from the floor and work upon them, sometimes half a dozen in a day. He never was “the perfect master of the brush” that we have heard him called, though he was an acceptable, and often a very powerful, technician. He usually began by basing a canvas in a warm gray or a raw umber tint, afterward sketching in with charcoal or pencil the general outline of forms and objects. His pigments at first were thin, and his canvas in its general distribution of masses was little more than stained. Upon that foundation he kept adding stronger notes, glazing his shadows to keep them transparent and push them back, and placing his opaque lights on top of the glaze. In this way he gradually developed the picture, keying up first one part and then another, until finally he drew the whole picture into unity and harmony.

It was most interesting to see Inness at work in this keying-up process. He always painted standing, and would walk backward and forward, putting on dabs here and rubs there with great expertness. He was a painter in oils, seldom employing any other medium, and yet he would use on his canvas almost anything that the impulse of the moment told him might prove effective. One day I watched him for fifteen minutes trying to deepen the shadows in a tree with a lead-pencil. The canvas was dry at the time and he did not want to put any more wet paint upon it. As he painted he talked, argued, declaimed, glared at you over the top of his glasses with apparently little embarrassment to himself or detriment to his canvas.

Painting he believed he had reduced to a scientific formula, but he kept changing the formula. Rules of procedure, too, he had in abundance, but they also kept shifting. At one time he insisted that a picture should have three planes—the middle plane to contain the centre of interest, the foreground to be a prologue, and the background an epilogue to this central plane. At another time he would spread a half-tone throughout the whole picture, keeping his sky low in key, and upon this neutral ground he would place lights and darks, making them brilliant and sparkling by contrast. Others before him—notably the Fontainebleau-Barbizon men—had worked with similar rules in mind, but Inness was quite original in his application. And he was always moving on to something new and better. Ripley Hitchcock quotes from one of his letters:

“I have changed from the time I commenced because I had never completed my art; and as I do not care about being a cake, I shall remain dough, subject to any impression which I am satisfied comes from the region of truth.”

What Inness was at the time he commenced may be gathered from another quotation from the same authority:

“My early and much of my later life was borne under the distress of a fearful nervous disease which very much impaired my ability to bear the painstaking in my studies which I could have wished. I began, of course, as most boys do, but without any art surroundings whatever. A boy now would be able to commence almost anywhere under better auspices than I could have had then, even in a city. I was in the barefoot stage, and, although my father was a well-to-do farmer, the boys dressed very much in Joseph’s coat style as to color, the different garments being equally variegated, while schooling consisted of the three R’s, and a ruler, with a rattan by way of change.”

At fourteen Inness received some instruction in drawing from a man named Barker, and at nineteen he was working as a map-engraver with Sherman and Smith in New York. It is said that he engraved several plates, but Inness himself evidently counted this apprenticeship of little value, for he later said:
