"Are these inscriptions taken from the Obelisk?" she queried, archly.
"No; they are copied from an inscription carved upon my heart."
"Oh, another stone, eh?"
"I wish it were a stone"—with a sigh. "But try my puzzle. I am deeply interested in it."
Maggie turned it over and over, held it edgeways this side and edgeways the other, but could make nothing of it.
"I am surprised you can not find it out," said Charley; "it is very transparent."
"Transparent? Oh, it is very transparent, is it? I see." And she held it up to the light, which, shining through the thin card, blended the two unmeaning inscriptions together so that they revealed distinctly a sentence, which she began to read:
"I lo—" Then suddenly checking herself, she said, with a laugh, "No you don't, Mr. Sparks; you don't trap me into any expression of adoration, as you did Miss Gooch. But tell me, how do you make these cards?"
"The simplest thing in the world. You take a piece of thin card-board, and outline on it in pencil any sentence you wish, as I have done 'I love you'; then you blacken portions of the letters, as I have also done, and place the card with its face to a window-pane, so that the light shining through will show what you have done on the other side. Complete the letters on the opposite side to the one on which you wrote the first part of your inscription, and the thing is done."
