Book Description:
THE PRACTICE & SCIENCE OF DRAWING
BY HAROLD SPEED
PREFACE
Permit me in the first place to anticipate the disappointment of any student who opens this book with the idea of finding wrinkles on how to draw faces, trees, clouds, or what not, short cuts to excellence in drawing, or any of the tricks so popular with the drawing masters of our grandmothers and still dearly loved by a large number of people. No good can come of such methods, for there are no short cuts to excellence. But help of a very practical kind it is the aim of the following pages to give; although it may be necessary to make a greater call upon the intelligence of the student than these Victorian methods attempted. It was not until some time after having passed through the course of training in two of our chief schools of art that the author got any idea of what drawing really meant.
