muttering curses and clenching his fists

The door jerked open, and the man flung past Martin, with an angry countenance and went down the corridor, muttering curses and clenching his fists. Martin decided not to enter immediately, and lingered in the hallways for a quarter of an hour. Then he shoved the door open and walked in. It was a new experience, the first time he had been inside an editorial office. Cards evidently were not necessary in that office, for the boy carried word to an inner room that there was a man who wanted to see Mr. Ford. Returning, the boy beckoned him from halfway across the room and led him to the private office, the editorial sanctum. Martin's first impression was of the disorder and cluttered confusion of the room. Next he noticed a bewhiskered, youthful-looking man, sitting at a roll-top desk, who regarded him curiously. Martin marvelled at the calm repose of his face. It was evident that the squabble with the printer had not affected his equanimity. I - I am Martin Eden," Martin began the conversation. ("And I want my five dollars," was what he would have liked to say.)
But this was his first editor, and under the circumstances he did not desire to scare him too abruptly. To his surprise, Mr. Ford leaped into the air with a "You don't say so!" and the next moment, with both hands, was shaking Martin's hand effusively. Can't say how glad I am to see you, Mr. Eden. Often wondered what you were like. Here he held Martin off at arm's length and ran his beaming eyes over Martin's second-best suit, which was also his worst suit, and which was ragged and past repair, though the trousers showed the careful crease he had put in with Maria's flat-irons. I confess, though, I conceived you to be a much older man than you are. Your story, you know, showed such breadth, and vigor, such maturity and depth of thought. A masterpiece, that story - I knew it when I had read the first half-dozen lines. Let me tell you how I first read it. But no; first let me introduce you to the staff."
Still talking, Mr. Ford led him into the general office, where he introduced him to the associate editor, Mr. White, a slender, frail little man whose hand seemed strangely cold, as if he were suffering from a chill, and whose whiskers were sparse and silky. Martin found himself shaking hands with a cranky-eyed, bald-headed man, whose face looked youthful enough from what little could be seen of it, for most of it was covered by a snow-white beard, carefully trimmed - by his wife, who did it on Sundays, at which times she also shaved the back of his neck.
The three men surrounded Martin, all talking admiringly and at once, until it seemed to him that they were talking against time for a wager.
