Have a holy horror of useless impasto, which gets sticky and dull, turns blue and heavy. When you have painted a bit of which you are doubtful, wait till the moment when it will be possible for you to take it out. Judge it; and if it is condemned, remove it firmly with your palette-knife, without rubbing by rags which spoil the limpidity of the pigment. You will have left a delicate foundation, to which you can return and finish with little labour, because your canvas will have received a first coating. Loading and massing the pigment is an abomination. In twenty-four hours gold turns to lead.

From the age of six I began to draw, and for eighty-four years I have worked independently of the schools, my thoughts all the time being turned towards drawing.
It being impossible to express everything in so small a space, I wished only to teach the difference between vermilion and crimson lake, between indigo and green, and also in a general way to teach how to handle round shapes and square, straight lines and curved; and if one day I make a sequel to this volume, I shall show children how to render the violence of ocean, the rush of rapids, the tranquillity of still pools, and among the living beings of the earth, their state of weakness or strength. There are in nature birds that do not fly high, flowering trees that never fruit; all these conditions of the life we live among are worth studying thoroughly; and if I ever succeed in convincing artists of this, I shall have been the first to show the way.
