[I] Pray do you remember carrying me to a picture-dealer's somewhere by Hanover Square, [London], and my being struck with the leaving and touch of a… - Thomas Gainsborough

Do you consider, my dear maggotty sir [cosy-name for his friend], what a deal of work history pictures require to what little dirty subjects of coal horses and jackasses and such figures as I fill up with; no, you don't consider anything about that part of the story.. .But to be serious (as I know you love to be), do you really think that a regular composition in the Landskip [landscape] way should ever be filled with History, or any figures but such as fill a place (I won't say stop a gap) or create a little business for the eye to be drawn from the trees in order to return to them with more glee.

When the streets are paved with brilliants and the skies made of rainbows I suppose you'll be contented and satisfied with red, blue and yellow.. ..how to satisfy your tawdry friends while you steal back into the mild evening gleam and quiet middle term[?]. I'll tell you, my sprightly genius, how this is to be done. Maintain all your lights, but spare the poor abused colours till the eye rests and recovers. Keep up your music by supplying the place of noise by more sound, more harmony and more tune, and split that cursed fife and drum.. ..he [Mr. Garrick] must feel the truth of what I am now saying, that neither our plays, paintings or music are any longer real works of invention, but the abuse of Nature's lights and what has been already invented in former times.

There is a branch of painting next in profit to Portrait and quite within your power without any more drawing them I'm answer for you having, which is Drapery & Land-skip.
