LILY (greatly relieved). Then may we only learn the three?

L. Certainly; unless, when you have got those three notions, you want to have some more notions;—which would not surprise me. But we'll try for the three, first. Katie, you broke your coral necklace this morning?

KATHLEEN. Oh! who told you? It was in jumping. I'm so sorry!

L. I'm very glad. Can you fetch me the beads of it?

KATHLEEN. I've lost some; here are the rest in my pocket, if I can only get them out.

L. You mean to get them out some day, I suppose; so try now. I want them.

(KATHLEEN empties her pocket on the floor. The beads disperse. The School disperses also. Second Interlude—hunting piece.)

L. (after waiting patiently for a quarter of an hour, to ISABEL, who comes up from under the table with her hair all about her ears and the last findable beads in her hand.) Mice are useful little things sometimes. Now, mousie, I want all those beads crystallized. How many ways are there of putting them in order?

ISABEL. Well, first one would string them, I suppose?

L. Yes, that's the first way. You cannot string ultimate atoms; but you can put them in a row, and then they fasten themselves together, somehow, into a long rod or needle. We will call these "NEEDLE-crystals." What would be the next way?
