CHAPTER I
INTRODUCTION
OF all the difficulties that hamper the speedy efficiency of an amateur artist, perspective is the most general and obstinate. The books which I have been privileged to publish on sketching, drawing, and painting have brought to me hundreds of letters, many of appreciation I am happy to say, but mostly prompted by a desire to know more. Let me speak plainly here.
If my earnest and energetic readers would thoroughly master the books even to the extent of many readings, I should receive many less letters of inquiry and, I hope, more of appreciation. In nine cases out of ten I have to repeat certain portions of the book with which my correspondent is so delighted. All teachers find that severity is an essential quality.
Well, I dare not be severe with you who read my books or you will buy no more, perhaps, and then my publishers would not like me. But, believe me, not one word of these little guides has been written carelessly or to make up the number, and all I ask is that you do not pass over a page until completely understood and that you do not neglect the book until you know all it contains. Not that the knowledge is rare, but it is to a great extent essential and, I firmly believe, valuable.
Dozens of go-aheads write to me about perspective. They want simple principles and rules by which they can quickly sketch sea, town, and country. This book is not a textbook on perspective. There are many complete studies of the subject. Here I have tried to give you short cuts to sound drawing for pictorial purposes and not for architectural designs.
I suppose that everyone knows what is perspective. All who have tried to draw even in the slightest degree know that objects appear to get smaller as they recede, but many have not the slightest idea what rules govern such an illusion and their variation under different circumstances. Hold your finger close to your eye, shutting the other, and see how much is hidden. Hold your pencil up in line with a distant tree and you find they appear equal in thickness. Why is it that the feet of a table’s legs are not in a line? If railway lines tend to join one another in the distance, how is one to estimate their slope? Where does one place the horizon? How does one draw two sides of a house in order to make it look true? These are a few of the many questions buzzing in the beginner’s brain.
The main difficulty is caused by the unquestionable and all-important fact that you must not draw things as you know they are, but as your eye registers them. You know full well that the railway lines do not draw nearer to one another, for the resulting mishap to the train would wreck it as surely as your picture will be wrecked if you draw the lines parallel.
“ Tell me not in mournful numbers... that things are not what they seem,” wrote Tennyson. Well, mournful news it may be to the beginner in art, but things certainly are not what they seem. The artist is concerned with what they seem. If parallel lines seem to join, you must join them; if horizontal lines seem tilted, you must tilt them; just as in the realm of colour, if a brown door appears purple, purple you must paint, and if green grass appears blue or grey, then do not make it green.
I have said enough, I hope, to whet your appetite and inspire a mite of curiosity for this weird world of contradictions into which we are going to step. Round lines nearly straight, a mile dwindling suddenly to an inch or two, a perfectly sober horizontal line leaping skywards, hands becoming bigger than houses—what a delicious world for Mr. Chesterton to plunge and splash in! And all under the dreaded, horrid word “perspective.” But, as in all fairy tales there are certain laws, passwords, and magic rules, so in perspective there are a few simple principles which, once grasped, will open up a riotous mass of shapes and forms never before seen.

CHAPTER II
LINES IN PERSPECTIVE
THE secret of the railway lines is our first mystery story. But as in most mystery stories, having discovered the facts of the case, that the lines appear to meet and yet in reality do not, we must start from another angle.
The first thing to establish when you intend to draw anything in perspective is your eye level. When I say “ anything in perspective,” I mean any line that goes away from you. Vertical lines, generally speaking, remain vertical to us. That is to say, two corners of a house or two vertical poles do not appear to meet as do railway lines. See Plate I, Fig. A. Also two lines running parallel to our eyes as drawn at Fig. B do not appear to join. Only lines going away from us, whatever their angle, seem to meet. See Fig. C.
Let us return to the eye level. This is the level of your eye and should be represented on paper by a straight line from side to side. The position of this line on the paper i...
