Lily. Oh, how nice of him! What a dear, brave crystal! But I can't bear to see his flanks all broken, and the clay within them.

L. Yes; it was an evil chance for him, the being born to such contention; there are some enemies so base that even to hold them captive is a kind of dishonour. But look, here has been quite a different kind of struggle: the adverse power has been more orderly, and has fought the pure crystal in ranks as firm as its own. This is not mere rage and impediment of crowded evil: here is a disciplined hostility; army against army.

Lily. Oh, but this is much more beautiful!

L. Yes, for both the elements have true virtue in them; it is a pity they are at war, but they war grandly.

Mary. But is this the same clay as in the other crystal?

L. I used the word clay for shortness. In both, the enemy is really limestone; but in the first, disordered, and mixed with true clay; while, here, it is nearly pure, and crystallises into its own primitive form, the oblique six-sided one, which you know: and out of these it makes regiments; and then squares of the regiments, and so charges the rock crystal literally in square against column.

Isabel. Please, please, let me see. And what does the rock crystal do?

L. The rock crystal seems able to do nothing. The calcite cuts it through at every charge. Look here,—and here! The loveliest crystal in the whole group is hewn fairly into two pieces.

Isabel. Oh, dear; but is the calcite harder than the crystal then?

L. No, softer. Very much softer.
