He took me over them, and it was very interesting, and some of it beautiful. You should see the liquid fire streaming on to the iron sheets, and then the sparkling lakes of gold, so intensely bright, like bits out of a setting sun sometimes. When I was going away, the manager pointed proudly to the mass of buildings we had been through, and said, 'This was all corn-fields a few years ago!' It sounded so cruel, and I could not help saying, 'Don't you think it was better growing corn than making glass?' He laughed, and seemed so amused; but I came away wondering, if this goes on, what will become of England. The tide is so strong--they will try to make money, at any price. And it is no use trying to remedy one evil, or another, unless the root is rooted out, is it?--the love of money." It is of use to remedy any evil you can reach: and all this will very soon now end in forms of mercantile catastrophe, and political revolution, which will end the "amusement" of managers, and leave the ground (too fatally) free, without "emigration." Oxford, 24th October. The Third Fors has just put into my hands, as I arrange my books here, a paper read before a Philosophical Society in the year 1870, (in mercy to the author, I forbear to give his name; and in respect to the Philosophical Society, I forbear to give its name,) which alleges as a discovery, by 'interesting experiment,' that a horizontal plank of ice laid between two points of support, bends between them; and seriously discusses the share which the 'motive power of heat' has in that amazing result. I am glad, indeed, to see that the author "cannot, without some qualifications agree" in the lucid opinion of Canon Moseley, that since, in the Canon's experiments, ice was crushed under a pressure of 308 lb. on the square inch, a glacier over 710 feet thick would crush itself to pieces at the bottom. (The Canon may still further assist modern science by determining what weight is necessary to crush an inch cube of water; and favouring us with his resulting opinion upon the probable depth of the sea.) But I refer to this essay only to quote the following passages in it, to prove, for future reference, the degree of ignorance to which the ingenuity of Professor Tyndall had reduced the general scientific public, in the year 1870:--
