China riveting is best left to practical men, but it can be done with a drill made from a splinter of a diamond fixed on a handle. If this is not to be had, get a small three-cornered file, harden it by placing it in the fire till red hot, and then plunging it in cold water. Next grind the point on a grindstone and finish on an oilstone. With the point pick out the place to be bored, taking care to do it gently for fear of breaking the article. In a little while a piece will break off, then the hole can easily be made by working the point round. The wire may then be passed through and fastened. A good cement may be made from 1 ounce of grated cheese, 1/2 ounce of finely powdered quicklime, and white of egg sufficient to make a paste. The less cement applied the better, using a feather to spread it over the broken edge.
