"Yes," said he, "John Knox was a true hero. He stood up manfully and fearlessly for the right when almost all the world was against him; and to do that requires a great deal of courage, as well as great strength of character. Many people reviled and hated him while he lived, but now his memory is universally honored. "I hope you two boys, when you come to be men," continued Mr. George, "will follow his example. What you know is right, that always defend, no matter if all the world are against it. And what is wrong, that always oppose, no matter if all the world are in favor of it." "Yes, sir," said Waldron, "I mean to." Mr. George and the boys rambled about the Necropolis some time longer, and then went on. While they were in Glasgow the party visited several of the great manufacturing establishments. They were all very much surprised at the loftiness of some of the chimneys. There was one at a great establishment, called the St. Rollox Chemical Works, which was over four hundred and thirty feet high, and Mr. George estimated that it must have been thirty or forty feet diameter at the base. If, now, you ask your father, or some friend, how high the steeple is of the nearest church to where you live, and multiply that height by the necessary number, you will get some idea of the magnitude of this prodigious column. The lightning rod, that came down the side of it in a spiral line, looked like a spider's web that had been, by chance, blown against the chimney by the wind. CHAPTER VII. ENTERING THE HIGHLANDS. The Highland district of Scotland occupies almost the whole of the western part of the island north of the valley of the Clyde. It consists of mountains, glens, and lakes, with roads winding in every direction through and among them. Of course the number of different Highland excursions which a tourist can plan is infinite. Most visitors to Scotland are, however, satisfied with a short tour among these mountains, on account of the great uncertainty of the weather. Indeed, as it rains here more than half the time, the chance is always in favor of bad weather; and the really pleasant days are very few. The valley by which tourists from Glasgow most frequently go into the Highlands is the valley of Loch Lomond. The lower end of this lake comes to within about ten miles of the Clyde. The upper end of it extends about twenty-five miles into the very heart of the Highlands. There is an inn at the lower end of the lake, that is, the end nearest the Clyde, called Balloch Inn. At the upper end of the lake is another resting-place for travellers. A small steamboat passes every day through the lake, from one of these inns to the other, touching at various intermediate points on the way, at little villages or landing-places, where roads from the interior of the country come down to the lake.
