The author of "Fors" had tried to show that the nineteenth-century commercialist spirit was not new; that the tyranny of capital was the old sin of usury over again; and he asked why preachers of religion did not denounce it--why, for example, the Bishop of Manchester did not, on simply religious grounds, oppose the teaching of the "Manchester School," who were the chief supporters of the commercialist economy. Not until the end of 1879 had Dr. Fraser been aware of the challenge; but at length he wrote, justifying his attitude. The popular and able bishop had much to say on the expediency of the commercial system and the error of taking the Bible literally; but he seemed unaware of the revolution in economical thought which "Unto this Last" and "Fors" had been pioneering. "I'm not gone to Venice yet," wrote Ruskin to Miss Beever, "but thinking of it hourly. I'm very nearly done with toasting my bishop; he just wants another turn or two, and then a little butter." The toasting and the buttering appeared in the _Contemporary Review_ for February 1880; and this incident led him to feel that the mission of "Fors" was not finished. If bishops were still unenlightened, there was yet work to do. He gave up Venice, and resumed his crusade. Brantwood life was occasionally interrupted by short excursions to London or elsewhere. In the autumn he had heard Professor Huxley on the evolution of reptiles; and this suggested another treatment of the subject, from his own artistic and ethical point of view, in a lecture oddly called "A Caution to Snakes," given at the London Institution, March 17th, 1880 (repeated March 23rd, and printed in "Deucalion"). He was not merely an amateur zoologist and F.Z.S., but a devoted lover and keen observer of animals. It would take long to tell the story of all his dogs, from the spaniel Dash, commemorated in his earliest poems, and Wisie, whose sagacity is related in "Præterita," down through the long line of bulldogs, St. Bernards, and collies, to Bramble, the reigning favourite; and all the cats who made his study their home, or were flirted with abroad. To Miss Beever, from Bolton Abbey (January 24th, 1875) he describes the Wharfe in flood, and then continues: "I came home (to the hotel) to quiet tea, and a black kitten called Sweep, who lapped half my cream-jugful (and yet I had plenty), sitting on my shoulder." Grip, the pet rook at Denmark Hill, is mentioned in "My First Editor," as celebrated in verse by Mr. W.H. Harrison.
