I am ashamed to give so many Drawings of my own, but I cannot find Studies by any other Draughtsman which unite the absolute fidelity to Natural Form, which I require from the Landscape student, with the Florentine Methods of outline. But also the very imperfections of these Drawings renders them, I think, a little more helpful as examples. If I could put a Study by Leonardo here, instead of this, though I fain would do so, the exquisiteness of his Shadow would make every student of good feeling so disgusted with his own work that he could scarcely proceed with it. It will be much better for him to advance less deE. spondently till he has learned to be disgusted with mine. Observe, also, that the method of this Study is, more or less, elementary. The outline is first made with the lead and then corrected and secured with the pen; so that the student following it may modify his lead-drawing till he is satisfied, and then pronounce the outline he has chosen. By Leonardo only one line would be drawn with his chalk or silver point, and in copying it, once missed it is missed for ever.
Pencil only, the outline secured by the pen. From a spray gathered at Verona, and now dry; you shall have a better one soon. It is of the real size, and too small for you to draw yet awhile; but it is placed here that Athena’s tree may be next Apollo’s. Take the next exercise instead.
