does it all mean?” he kept repeating mechanically.
Upon my honour I could not have enlightened him. Besides he did not ask me, and he went on talking to himself.
“This is what is called a cryptogram, or cipher,” he said, “in which letters are purposely thrown in confusion, which if properly arranged would reveal their sense. Only think that under this jargon there may lie concealed the clue to some great discovery!”
As for me, I was of opinion that there was nothing at all, in it; though, of course, I took care not to say so.
Then the Professor took the book and the parchment, and diligently compared them together.
“These two writings are not by the same hand,” he said; “the cipher is of later date than the book, an undoubted proof of which I see in a moment. The first letter is a double m, a letter which is not to be found in Turlleson’s book, and which was only added to the alphabet in the fourteenth century. Therefore there are two hundred years between the manuscript and the document.”
I admitted that this was a strictly logical conclusion.
“I am therefore led to imagine,” continued my uncle, “that some possessor of this book wrote these mysterious letters. But who was that possessor? Is his name nowhere to be found in the manuscript?”
My uncle raised his spectacles, took up a strong lens, and carefully examined the blank pages of the book. On the front of the second, the title-page, he noticed a sort of stain which looked like an ink blot. But in looking at it very closely he thought he could distinguish some half-effaced letters. My uncle at once fastened upon this as the centre of interest, and he laboured at that blot, until by the help of his microscope he ended by making out the following Runic characters which he read without difficulty.
“Arne Saknussemm!” he cried in triumph. “Why that is the name of another Icelander, a savant of the sixteenth century, a celebrated alchemist!”
I gazed at my uncle with satisfactory admiration.
“Those alchemists,” he resumed, “Avicenna, Bacon, Lully, Paracelsus, were the real and only savants of their time. They made discoveries at which we are astonished. Has not this Saknussemm concealed under his cryptogram some surprising invention? It is so; it must be so!”
The Professor’s imagination took fire at this hypothesis.
“No doubt,” I ventured to reply, “but what interest would he have in thus hiding so marvellous a discovery?”
“Why? Why? How can I tell? Did not Galileo do the same by Saturn? We shall see. I will get at the secret of this document, and I will neither sleep nor eat until I have found it out.”
My comment on this was a half-suppressed “Oh!”
“Nor you either, Axel,” he added.
“The deuce!” said I to myself; “then it is lucky I have eaten two dinners to-day!”
“First of all we must find out the key to this cipher; that cannot be difficult.”
At these words I quickly raised my head; but my uncle went on soliloquising.
“There’s nothing easier. In this document there are a hundred and thirty-two letters, viz., seventy-seven consonants and fifty-five vowels. This is the proportion found in southern languages, whilst northern tongues are much richer in consonants; therefore this is in a southern language.”
These were very fair conclusions, I thought.
“But what language is it?”
Here I looked for a display of learning, but I met instead with profound analysis.
“This Saknussemm,” he went on, “was a very well-informed man; now since he was not writing in his own mother tongue, he would naturally select that which was currently adopted by the choice spirits of the sixteenth century; I mean Latin. If I am mistaken, I can but try Spanish, French, Italian, Greek, or Hebrew. But the savants of the sixteenth century generally wrote in Latin. I am therefore entitled to pronounce this, à priori, to be Latin. It is Latin.”
I jumped up in my chair. My Latin memories rose in revolt against the notion that these barbarous words could belong to the sweet language of Virgil.
“Yes, it is Latin,” my uncle went on; “but it is Latin confused and in disorder; ‘pertubata seu inordinata,‘ as Euclid has it.”
“Very well,” thought I, “if you can bring order out of that confusion, my dear uncle, you are a clever man.”
“Let us examine carefully,” said he again, taking up the leaf upon which I had written. “Here is a series of one hundred and thirty-two letters in apparent disorder. There are words consisting of consonants only, as nrrlls; others, on the other hand, in which vowels predominate, as for instance the fifth, uneeief, or the last but one, oseibo. Now this arrangement has evidently not been premeditated; it has arisen mathematically in obedience to the unknown law which has ruled in the succession of these letters. It appears to me a certainty that the original sentence was written in a proper manner, and afterwards distorted by a law which we have yet to discover. Whoever possesses the key of this cipher will read it with fluency. What is that key? Axel, have you got it?”
I answered not a word, and for a very good reason. My eyes had fallen upon a charming picture, suspended against the wall, the portrait of Gräuben. My uncle’s ward was at that time at Altona, staying with a relation, and in her absence I was very downhearted; for I may confess it to you now, the pretty Virlandaise and the professor’s nephew loved each other with a patience and a calmness entirely German. We had become engaged unknown to my uncle, who was too much taken up with geology to be able to enter into such feelings as ours. Gräuben was a lovely blue-eyed blonde, rather given to gravity and seriousness; but that did not prevent her from loving me very sincerely. As for me, I adored her, if there is such a word in the German language. Thus it happened that the picture of my pretty Virlandaise threw me in a moment out of the world of realities into that of memory and fancy.
There looked down upon me the faithful companion of my labours and my recreations. Every day she helped me to arrange my uncle’s precious specimens; she and I labelled them together. Mademoiselle Gräuben was an accomplished mineralogist; she could have taught a few things to a savant. She was fond of investigating abstruse scientific questions. What pleasant hours we have spent in study; and how often I envied the very stones which she handled with her charming fingers.
Then, when our leisure hours came, we used to go out together and turn into the shady avenues by the Alster, and went happily side by side up to the old windmill, which forms such an improvement to the landscape at the head of the lake. On the road we chatted hand in hand; I told her amusing tales at which she laughed heartilv. Then we reached the banks of the Elbe, and after having bid good-bye to the swan, sailing gracefully amidst the white water lilies, we returned to the quay by the steamer.
That is just where I was in my dream, when my uncle with a vehement thump on the table dragged me back to the realities of life.
“Come,” said he, “the very first idea which would come into any one’s head to confuse the letters of a sentence would be to write the words vertically instead of
