ion bricks, stones, bits of glass, etc., "Fly up through earth, water, and air, and combine into a perfect palace, with walls, buttresses, towers, and windows all in exact architectural harmony." But there is such a law and force for crystals, if not for palaces. There is wisdom to originate and power to manage such a force. It does not take masses of rock and stick them together, nor even particles from a fluid, but atoms from a gas. Atoms as fine as those of air must be taken and put in their place, one by one, under enormous pressure, to have the resulting crystal as compact as a diamond. The force of crystallization is used by us in many inferior ways, as in making crystals of rock candy, sulphur, salt, etc., but for the making of diamonds it is too much for us, except in a small way. While we cannot yet use the force that builds large white diamonds we can use the diamonds themselves. Set a number of them around a section of an iron tube, place it against a rock, at the surface or deep down in a mine, cause it to revolve rapidly by machinery, and it will bore into the rock, leaving a core. Force in water, to remove the dust and chips, and the diamond teeth will eat their way hundreds of feet in any direction; and by examining the extracted core miners can tell what sort of ore there is hundreds of feet in advance. Hence, they go only where they know that value lies. SOME CURIOUS BEHAVIORS OF ATOMS Ultimate atoms of matter are asserted to be impenetrable. That is, if a mass of them really touched each other, that mass would not be condensible by any force. But atoms of matter do not touch. It is thinkable, but not demonstrable, that condensation might go on till there were no discernible substance left, only force. Matter exists in three states: solid, liquid, and gas. It is thought that all matter may be passed through the three stages--iron being capable of being volatilized, and gases condensed to liquids and solids--the chief difference of these states being greater or less distance between the constituent atoms and molecules. In gas the particles are distant from each other, like gnats flying in the air; in liquids, distant as men passing in a busy street; in solids, as men in a congregation, so sparse that each can easily move about. The congregation can easily disperse to the rarity of those walking in the street, and the men in the street condense to the density of the congregat
