He was true to others. No accusation had ever been brought forward against Turner by his most envious enemies, of his breaking a promise, or failing in an undertaken trust. His sense of justice was strangely acute; it was like his sense of balance in color, and shone continually in little crotchets of arrangement of price, or other advantages, among the buyers of his pictures. For instance, one of my friends had long desired to possess a picture which Turner would not sell. It had been painted with a companion; which was sold, but this reserved. After a considerable number of years had passed, Turner consented to part with it. The price of canvases of its size having, in the meantime, doubled, question arose as to what was then to be its price. "Well," said Turner, "Mr. ---- had the companion for so much. You must be on the same footing." This was in no desire to do my friend a favor; but in mere instinct of equity. Had the price of his pictures fallen, instead of risen in the meantime, Turner would have said, "Mr. ---- paid so much, and so must you." But the best proof to which I can refer in this character of his mind is in the wonderful series of diagrams executed by him for his lectures on perspective at the Royal Academy. I had heard it said that these lectures were inefficient. Barely intelligible in expression they might be; but the zealous care with which Turner endeavored to do his duty, is proved by a series of large drawings, exquisitely tinted, and often completely colored, all by his own hand, of the most difficult perspective subjects; illustrating not only directions of line, but effects of light, with a care and completion which would put the work of any ordinary teacher to utter shame. In teaching generally, he would neither waste his time nor spare it; he would look over a student's drawing, at the academy,--point to a defective part, make a scratch on the paper at the side, saying nothing; if the student saw what was wanted, and did it, Turner was delighted, and would go on with him, giving hint after hint; but if the student could not follow, Turner left him. Such experience as I have had in teaching, leads me more and more to perceive that he was right. Explanations are wasted time. A man who can see, understands a touch; a man who cannot, misunderstands an oration.
