How brilliant this collection of gems looks; how the stones sparkle! they have been sent as specimens of the jewels which Ireland produces. But here are some pretty English agates; and a huge mass of Irish rock crystal, which is very bright and clear. In a compartment, at a little distance, we may see a book, bound according to a new method, by which the leaves are so firmly placed together, that they would not loosen in ten years' time, no matter how the book was tossed about, unless they were purposely taken out. We must now have a look at the machinery department. Firstly, there is the great steam-engine that works all the other steam-engines in the Exhibition, though, of course, you cannot understand it by looking at it; neither can I, although I know so much more than you do. Near it is a model of a new agricultural machine for cutting, turning up, and making into light mould, the clay of fields, so as to make it ready to receive the seeds to be set, without the farmers being obliged to plough the earth. There is a machine for making bricks and tiles, so that people may, if they like, form those materials for building houses cheaper and better than in the usual way. But here is a useful machine. It is a measuring machine, by which you could measure to the smallest size, even to the hundred-thousandth part of an inch! Here is a very pretty contribution; it is a model of the house of the great play-writer, Shakspeare,--of whom, perhaps, you may have heard,--and it is surrounded by figures representing different beautiful scenes from Shakspeare's plays. It was made by a workman in his leisure time: and it certainly does him credit. It is called the Shakspeare Jubilee. Yonder is another piece of ingenious industry; it is a group of figures showing all the various Scotch games; there is one figure dancing the Highland fling, another throwing the beam, and all the others engaged in similar sports. That came from Scotland, of course.
