Publisher's Synopsis
Some people think it great fun to build a house of cards slowly and anxiously, and then knock it to pieces with one little snip of the finger. Or to fix up a snow man in fine style and watch a sudden thaw melt him out of sight. Or to write a name carefully, like a copy-book, and with many curlicues, in the wet sand, and then scamper off and let the first high wave smooth it away as a boy's sponge wipes from his slate some such marvelous statement as, 12 x 12 = 120, or 384"
