"Landscape," by Sontag. A mountain lake is curious about Sontag's pictures. They sell well and most people admire them, yet no one ever saw his colors authenticated in nature. He idealizes the views he finds, or creates what he never saw, but his pictures have a certain vigor and fanciful beauty that please. The best one we ever saw of his is now in the exhibition at the Fair. A mountainous region, with gray clouds rolling off the high land. The placid lake (an invariable feature in his pictures) is delineated in its steely calm with his usual power and usual defect; still the whole picture, particularly the clouds, fawns and mountains, has the freedom and force of genius, if a little crotchety and erroneous.
