"The old man [Turner's father] latterly was his son's willing slave, and had to strain his pictures, and varnish them when finished; which made Turner say that his father began and finished his pictures for him. But I doubt if he varnished many pictures; few of them, I believe, were varnished at all; still he was of great assistance to his son, and I think it was Mr. Turner the engraver who told me that, once making bold to enter Turner's studio, he found the old man on his knees colouring a canvas, when Turner made his appearance, and good-humouredly trundled out the visitor [Turner, the engraver], telling him he was on forbidden ground. Turner was much attached to his father, and at his death stayed with us a few days at Heston for change of scene. He was fearfully out of spirits, and felt his loss, he said, like that of an only child.. .Turner never appeared the same man after his father's death [in 1829]; his family was broken up.."
