“I cannot say that I do,” answered Roger, “unless you mean that they are arranged in groups of four.”
“Yes, that is certainly so,” agreed Harry; “but there is somewhat else of significance, and that is, that, although they are grouped in fours for the most part, there are two groups of six figures, one of two, and one figure stands alone. These being different from the remainder of the cipher, we may at once set them down as denoting something different from the rest of the writing. I should say that possibly some direction, instruction, or it may even be a compass-bearing, is concealed in these two groups of six figures, while, to my mind, the figures 14 and 5, are to be read as they really are, that is as figures only; for I believe that the remainder of the figures stand for words or letters, as indeed they must, if any sense is to be made of the thing. Yes, the more I study this, the more certain am I that we have found something of value, and this, I am convinced, is the document you told me Alvarez was looking for while you were in the cabin of the sinking Gloria del Mundo.”
“By Saint George,” said Roger, “I am inclined to believe you are right, Harry; only I see not how it will benefit us if we cannot translate the cipher, and that seems to me impossible without the key thereto.”
“Nothing is impossible, my friend,” retorted Harry. “We have no key, it is true, but by repeated experiments we shall solve the thing eventually, I am sure.”
“Let us start trying right now, then,” suggested Roger.
“Well, starting from the beginning, let us take the first group of—”
“Mr Trevose, hie you on deck, if you please; I want you,” came Cavendish’s voice down the companion at this moment, putting an abrupt end to the operations on the cipher.
Leaving Harry to put away the document in safety, Roger ran up on deck, and touched his hat to his captain.
“Mr Trevose,” said Cavendish, “one of the boats has just come off from the shore with a load of fresh fruit and vegetables which the men have collected. They have now had a short spell ashore, and it is time for us to be thinking of work again; so I wish you to take this boat and proceed to the shore in her with instructions to Mr Leigh to collect all the men forthwith. Let them bring off as much fruit and vegetables as they can find, but they must not be very long about it. You can take your friend Edgwyth with you, if you will, and while the men are getting fresh provisions together you and he have my leave, after you have delivered my message, to do as you please until all are ready to come off aboard.
“And have a care,” added the skipper, “that you two lads do not get into any further scrapes. You had a particularly narrow escape this morning, both of you, and perchance may not get off quite so easily next time.”
