LETTER I.
MY DEAR GEORGE AND ELIZA,
I shall commence my written instructions on the art of drawing, by informing
you that it is impossible to obtain proficiency in this delightful accomplishment,
without great industry and regular application. The student in drawing can derive
but little benefit from lessons given at irregular and distant intervals of time, as the
knowledge gained thus in one lesson, is lost before it can be applied in another. I
therefore advise you to devote an hour and a half, three days in the week, to this
pursuit; it is not of much consequence what part of the day, but were it convenient,
I should prefer the morning.
