Now take the first group of figures, which is 2227. Divided into two groups of two figures each, and added to one another, as we intend to proceed, this makes 49. Now what letter corresponds to the number 49? We find that the letter I does. Take the next group, which is 1819. This resolves itself into 37, and H is the letter belonging to that figure. From 1919 we get 38, and the letter I; and from 2622 comes 48, and the letter S. Now you see, Harry, that by this method we have already got the English word `This'; and from that it would seem that we are at last on the right track for translating the cryptogram. From the next two groups we get the word `is', and from the following three the word `the'. I think now, Harry, that we may begin and write down the translation as we go along; for I feel sure that we are right at last. It would be more than mere coincidence if the words `This is the' were not part of a connected and intelligible whole. So just hand me that knife, Harry, boy, and I will produce the necessary ink.
