249 NINETEENTH EVENING. ON METALS.—PANT I, George and Harry, with their Tutor, one day in their walk were driven by the rain to take shelter in a blacksmith’s shed. The shower lasting some time, the boys, in order to amuse themselves, began to examine the things around them. The great bellows first attracted their notice, and they admired the roaring it made, and the expedition with which it raised the fire to a heat too intense for them to look at. They were surprised at the dexterity with which the smith fashioned a bar of iron into a horse-shoe ; first heating it, then hammering it well on the anvil, cutting offa proper length, bending it round, turning up the ends, and, lastly, punching the nail-holes. They watched the whole process of fitting it to the horse’s foot, and fastening 1b on; and it had become fair some ininutes before they showed a desire to leave the shop and proceed on their walk. “7 could never have thought,” said George, beginning the conversation, “ that such a hard thing as iron could have been so easily managed.” “ Nor J, neither,” said Harry. Tut. It was managed, you saw, by the help of fire. The fire made it soft and flexible, so that the smitk could easily hammer it, and cut it, and bend it to the shape he wanted ; and then dipping it in water, made it hard again. G. Are all other metals managed in the same manner 7. They are all worked by the help of fire in some way or other, either in melting them, or making them soft. G. There are many sorts of metals, are there not ?
