I was asleep on the deck of the _Mindinao_, dead tired after a fruitless hike.

I dreamed she came toward me through a young woodland all lighted by the sun, and in her hands she held masses of that wild flower we call Solomon's Seal.

And she said--in the voice I know must be like hers: 'If you could only read! If you would only understand the message I send you! It is everywhere on earth for you to read, if you only would!' "I said: 'Is the message in the seal?
Is that the key to it ?' "She nodded, laughing, burying her face in the flowers, and said: "'Perhaps I can write it more plainly for you some day; I will try very, very hard.' "And after that she went away--not swiftly--for I saw her at moments far away in the woods; but I must have confused her with the glimmering shafts of sunlight, and in a little while the woodland grew dark and I woke with the racket of a Colt's automatic in my ears."

"I am copying what I see through this magnifying glass written on the window pane in the photograph," said the Tracer calmly.

"Can't you see those marks ?" "I--I do now; I never noticed them before particularly--only that there were scratches there." When at length the Tracer had finished his work he sat, chin on hand, examining it in silence.
