As to drawing, no one can have a better drawing-teacher than himself. Remember that. And whoever can learn to write can learn to draw. Of all the boys who have ever entered at the Worcester Technical School, it has proved that all could draw, and I think the same is true at West Point. Keep your drawings, not to show to other people, but to show yourself whether you are improving. And thank me, ten years hence, that I advised you to do so.
You do not expect me to go into detail as to the method in which you can teach yourself. This is, however, sure. If you will determine to learn to see things truly, you will begin to draw them truly. It is, for instance, almost never that the wheel of a carriage really is round to your eye. It is round to your thought. But unless your eye is exactly opposite the hub of the wheel in the line of the axle, the wheel does not make a circle on the retina of your eye, and ought not to be represented by a circle in your drawing. To draw well, the first resolution and the first duty is to see well. Second, do not suppose that mere technical method has much to do with real success. Soft pencil rather than hard; sepia rather than India ink. It is pure truth that tells in drawing, and that is what you can gain. Take perfectly simple objects, at a little distance, to begin with. Yes, the gate-posts at the garden gate are as good as anything. Draw the outline as accurately as you can, but remember there is no outline in nature, and that the outline in drawing is simply conventional; represent--which means present again, or re-present--the shadows as well as you can. Notice is the shadow under the cap of the post deeper than that of the side. Then let it be re-presented so on your paper. Do this honestly, as well as you can. Keep it to compare with what you do next week or next month. And if you have a chance to see a good draughtsman work, quietly watch him, and remember. Do not hurry, nor try hard things at the beginning. Above all, do not begin with large landscapes.
As for singing, there is nothing that so lights up a whole house as the strain, through the open windows, of some one who is singing alone. We feel sure, then, that there is at least one person in that house who is well and is happy.
