"Yes," I replied, "if you think them worth the price. But if you do, you rate them even more highly than they rate themselves; and English colonists are not much behind the citizens of the model Republic in honest self-esteem."
"Wal," he said, "how much du yew calc'late we shall hev to pay?"
"Not more, perhaps, than you can afford; only California, and every
Atlantic seaport from Portland to Galveston."
"Reckon yew may be about right, stranger," he said, falling back with tolerable good-humour; and, to do them justice, the bystanders seemed to think the retort no worse than the provocation deserved.
"I am sorry," said my friend, "you should have fallen in with so unpleasant a specimen of the character your countrymen ascribe with too much reason to Americans. I have been long in England, and never met with such discourtesy from any one who recognised me as an American."
After this our conversation became less reserved; and I found that I was conversing with one of the most renowned officers of irregular cavalry in the late Confederate service—a service which, in the efficiency, brilliancy, and daring of that especial arm, has never been surpassed since Maharbal's African Light Horse were recognised by friends and foes as the finest corps in the small splendid army of Hannibal.
Colonel A—— (the reader will learn why I give neither his name nor real rank) spoke with some bitterness of the inquisitiveness which rendered it impossible, he said, to trust an American with a secret, and very difficult to keep one without lying. We were presently joined by Major B——, who had been employed during the war in the conduct of many critical communications, and had shown great ingenuity in devising and unravelling ciphers. On this subject a somewhat protracted discussion arose. I inclined to the doctrine of Poe, that no cipher can be devised which cannot be detected by an experienced hand; my friends indicated simple methods of defeating the processes on which decipherers rely.
"Poe's theory," said the Major, "depends upon the frequent recurrence of certain letters, syllables, and brief words in any given language; for instance, of e's and t's, tion and ed, a, and, and the in English. Now it is perfectly easy to introduce abbreviations for each of the common short words and terminations, and equally easy to baffle the decipherer's reliance thereon by inserting meaningless symbols to separate the words; by employing two signs for a common letter, or so arranging your cipher that no one shall without extreme difficulty know which marks stand for single and which for several combined letters, where one letter ends and another begins."
After some debate, Colonel A—— wrote down and handed me two lines in a cipher whose character at once struck me as very remarkable.
"I grant," said I, "that these hieroglyphics might well puzzle a more practised decipherer than myself. Still, I can point out even here a clue which might help detection. There occur, even in these two lines, three or four symbols which, from their size and complication, are evidently abbreviations. Again, the distinct forms are very few, and have obviously been made to serve for different letters by some slight alterations devised upon a fixed rule. In a word, the cipher has been constructed upon a general principle; and though it may take a long time to find out what that principle is, it affords a clue which, carefully followed out, will probably lead to detection."
