and were content to be themselves, and with them Martin was content to forget how noble he was. He had for them an affection such as he had for no one at the University save Max Gottlieb.
He carried in his bag one book, Gottlieb’s “Immunology.” He could often get through half a page of it before he bogged down in chemical formulae. Occasionally, on Sundays or rainy days, he tried to read it, and longed for the laboratory; occasionally he thought of Madeline Fox, and became certain that he was devastatingly lonely for her. But week slipped into careless and robust week, and when he awoke in a stable, smelling the sweet hay and the horses and the lark-ringing prairie that crept near to the heart of these shanty towns, he cared only for the day’s work, the day’s hiking, westward toward the sunset.
So they straggled through the Montana wheatland, whole duchies of wheat in one shining field, through the cattle-country and the sagebrush desert, and suddenly, staring at a persistent cloud, Martin realized that he beheld the mountains.
Then he was on a train; the wire-gang were already forgotten; and he was thinking only of Madeline Fox, Clif Clawson, Angus Duer, and Max Gottlieb.
Chapter IV
I
Professor Max Gottlieb was about to assassinate a guinea pig with anthrax germs, and the bacteriology class were nervous.
They had studied the forms of bacteria, they had handled Petri dishes and platinum loops, they had proudly grown on potato slices the harmless red cultures of Bacillus prodigiosus, and they had come now to pathogenic germs and the inoculation of a living animal with swift disease. These two beady-eyed guinea pigs, chittering in a battery jar, would in two days be stiff and dead.
Martin had an excitement not free from anxiety. He laughed at it, he remembered with professional scorn how foolish were the lay visitors to the laboratory, who believed that sanguinary microbes would leap upon them from the mysterious centrifuge, from the benches, from the air itself. But he was conscious that in the cotton-plugged test-tube between the instrument-bath and the bichloride jar on the demonstrator’s desk were millions of fatal anthrax germs.
The class looked respectful and did not stand too close. With the flair of technique, the sure rapidity which dignified the slightest movement of his hands, Dr. Gottlieb clipped the hair on the belly of a guinea pig held by the assistant. He soaped the belly with one flicker of a hand-brush, he shaved it and painted it with iodine.
(And all the while Max Gottlieb was recalling the eagerness of his first students, when he had just returned from working with Koch and Pasteur, when he was fresh from enormous beer seidels and Korpsbrüder and ferocious arguments. Passionate, beautiful days! Die goldene Zeit! His first classes in America, at Queen City College, had been awed by the sensational discoveries in bacteriology; they had crowded about him reverently; they had longed to know. Now the class was a mob. He looked at them—Fatty Pfaff in the front row, his face vacant as a doorknob; the co-eds emotional and frightened; only Martin Arrowsmith and Angus Duer visibly intelligent. His memory fumbled for a pale blue twilight in Munich, a bridge and a waiting girl, and the sound of music.)
He dipped his hands in the bichloride solution and shook them—a quick shake, fingers down, like the fingers of a pianist above the keys. He took a hypodermic needle from the instrument-bath and lifted the test-tube. His voice flowed indolently, with German vowels and blurred W’s:
“This, gentlemen, iss a twenty-four-hour culture of Bacillus anthracis. You will note, I am sure you will have noted already, that in the bottom of the tumbler there was cotton to keep the tube from being broken. I cannot advise breaking tubes of anthrax germs and afterwards getting the hands into the culture. You might merely get anthrax boils—”
The class shuddered.
Gottlieb twitched out the cotton plug with his little finger, so neatly that the medical students who had complained, “Bacteriology is junk; urinalysis and blood tests are all the lab stuff we need to know,” now gave him something of the respect they had for a man who could do card tricks or remove an appendix in seven minutes. He agitated the mouth of the tube in the Bunsen burner, droning, “Every time you take the plug from a tube, flame the mouth of the tube. Make that a rule. It is a necessity of the technique, and technique, gentlemen, iss the beginning of all science. It iss also the least-known thing in science.”
The class was impatient. Why didn’t he get on with it, on to the entertainingly dreadful moment of inoculating the pig?
(And Max Gottlieb, glancing at the other guinea pig in the prison of its battery jar, meditated, “Wretched innocent! Why should I murder him, to teach Dummköpfe? It would be better to experiment on that fat young man.”)
He thrust the syringe into the tube, he withdrew the piston dextrously with his index finger, and lectured:
“Take one half c.c. of the culture. There are two kinds of M.D.’s—those to whom c.c. means cubic centimeter and those to whom it means compound cathartic. The second kind are more prosperous.”
(But one cannot convey the quality of it: the thin drawl, the sardonic amiability, the hiss of the S’s, the D’s turned into blunt and challenging T’s.)
The assistant held the guinea pig close; Gottlieb pinched up the skin of the belly and punctured it with a quick down thrust of the hypodermic needle. The pig gave a little jerk, a little squeak, and the co-eds shuddered. Gottlieb’s wise fingers knew when the peritoneal wall was reached. He pushed home the plunger of the syringe. He said quietly, “This poor animal will now soon be dead as Moses.” The class glanced at one another uneasily. “Some of you will think that it does not matter; some of you will think, like Bernard Shaw, that I am an executioner and the more monstrous because I am cool about it; and some of you will not think at all. This difference in philosophy iss what makes life interesting.”
While the assistant tagged the pig with a tin disk in its ear and restored it to the battery jar, Gottlieb set down its weight in a note-book, with the time of inoculation and the age of the bacterial culture. These notes he reproduced on the blackboard, in his fastidious script, murmuring, “Gentlemen, the most important part of living is not the living but pondering upon it. And the most important part of experimentation is not doing the experiment but making notes, ve-ry accurate quantitative notes—in ink. I am told that a great many clever people feel they can keep notes in their heads. I have often observed with pleasure that such persons do not have heads in which to keep their notes. This iss very good, because thus the world never sees their results and science is not encumbered with them. I shall now inoculate the second guinea pig, and the class will be dismissed. Before the next lab hour I shall be glad if you will read Pater’s ‘Marius the Epicurean,’ to derife from it the calmness which iss the secret of laboratory skill.”

As they bustled down the hall, Angus Duer observed to a brother Digam, “Gottlieb is an old laboratory plug; he hasn’t got any imagination; he sticks here instead of getting out into the world and enjoying the fight. But he certainly is handy. Awfully good technique. He might have been a first-rate surgeon, and made fifty thousand dollars a year. As it is, I don’t suppose he gets a cent over four thousand!”
Ira Hinkley walked alone, worrying. He was an extraordinarily kindly man, this huge and bumbling parson. He reverently accepted everything, no matter how contradictory to everything else, that his medical instructors told him, but this killing of animals—he hated it. By a connection not evident to him he remembered that the Sunday before, in the slummy chapel where he preached during his medical course, he had exalted the sacrifice of the martyrs and they had sung of the blood of the lamb,
