Sunshine is delicious, rain is refreshing, wind braces us up, snow is exhilarating; there is really no such thing as bad weather, only different kinds of good weather.
Expression, sentiment, truth to nature, are essential: but all those are not enough. I never care to look at a picture again, if it be ill composed; and if well composed I can hardly leave off looking at it.
