The Mr. Ramirez who reached the busy thoroughfare again was so different from the Mr. Ramirez who twenty minutes before had entered the Arcade that his identity might have easily been doubted. He did not even breathe in the same way; his cheek, although haggard, had resumed its colour; his eyes, which hitherto had been fixed and contemplative, had returned to their usual restless vivacity. With the exception that at first he walked quickly on leaving the saloon, and once or twice hurriedly turned to see if anybody were following him, his manner was totally changed. And this without effusion of blood, or the indulgence of an insatiable desire for revenge! As I prefer to deal with Mr. Ramirez without affecting to know any more of that gentleman than he did himself, I am unable to explain any more clearly than he did to himself the reason for this change in his manner, or the utter subjection of his murderous passion. When it is remembered that for several hours he had had unlimited indulgence, without opposition, in his own instincts, but that for the last twenty minutes he had some reason to doubt their omnipotence, perhaps some explanation may be adduced. I only know that by half-past six Mr. Ramirez had settled in his mind that physical punishment of his enemies was not the most efficacious means of revenge, and that at half-past seven he had concluded _not_ to take the Sacramento boat. And yet for the previous six hours I have reason to believe that Mr. Ramirez was as sincere a murderer as ever suffered the penalty of his act, or to whom circumstances had not offered a Mr. Hamlin to act upon a constitutional cowardice. Mr. Ramirez proceeded leisurely down Montgomery Street until he came to Pacific Street. At the corner of the street his way was for a moment stopped by a rattling team and waggon that dashed off through the fog in the direction of the wharf. Mr. Ramirez recognised the express and mail for the Sacramento boat. But Mr. Ramirez did not know that the express contained a letter which ran as follows-- "DEAR MADAM,--Yours of the 10th received, and contents noted. Am willing to make our services contingent upon your success. We believe your present course will be quite as satisfactory as the plan you first proposed. Would advise you not to give a personal interview to Mr. Ramirez, but refer him to Mr. Gabriel Conroy. Mr. Ramirez's manner is such as to lead us to suppose that he might offer violence, unless withheld by the presence of a third party.--Yours respectfully, "PETER DUMPHY." CHAPTER II.
