wisteria climbed high over the old bricks of the tall Georgian house. In
   the cobbled yard at the foot of the garden he looked up at the rooks
   making their din high in the overhanging elms and he gazed for a few
   moments through the trees to where you could see the bare ribs of the
   fells still showing the last white runners of winter.
   "Charming," he murmured. "Charming."
   I was glad enough to see him to his lodgings that evening. I felt I
   needed time to readjust my thinking.
   When we started out next morning I saw he had discarded his check suit
   but was still very smart in a hacking jacket and flannels.
   "Haven't you any protective clothing?" I asked.
   "I've got these." He indicated a spotless pair of Wellingtons in the
   back of the car.
   "Yes, but I mean an oilskin or a coat of some kind. Some of our jobs are
   pretty dirty."
   He smiled indulgently. "Oh, I'm sure I'll be all right. I've been round
   the farms before, you know."
   I shrugged my shoulders and left it at that.
   Our first visit was to a lame calf. The little animal was limping round
   its pen holding up a fore leg and looking very woebegone. The knee was
   visibly swollen and as I palpated it there seemed to be a lumpiness in
   the fluid within as if there might be a flocculus of pus among it. The
   temperature was a hundred and four.
   I looked up at the farmer. "This is joint ill. He probably got ah
   infection through his navel soon after birth and it's settled in his
   knee. We'll have to take care of him because his internal organs such as
   the liver and lungs can be affected. I'll give him an injection and
   leave you some tablets for him."
   I went out to the car and when I came back Carmody was bending over the
   calf, feeling at the distended knee and inspecting the navel closely. I
   gave my injection and we left.
   "You know," Carmody said as we drove out of the yard, 'that wasn't joint
   ill."
   "Really?" I was a bit taken aback. I didn't mind students discussing the
   pros and cons of my diagnoses as long as they didn't do it in front of
   the farmer, but I had never had one tell me bluntly that I was wrong. I
   made a mental note to try to keep this fellow away from Siegfried; one
   remark like that and Siegfried would hurl him unhesitatingly out of the
   car, big as he was.
   "How do you make that out, then?" I asked him.
   "Well there was only the one joint involved and the navel was perfectly
   dry. No pain or swelling there. I should say he just sprained that
   knee."
   "You may be right, but wouldn't you say the temperature was a bit high
   for a sprain?"
   Carmody grunted and shook his head slightly. Apparently he had no
   doubts.
   A few gates cropped up in the course of our next batch of calls and
   Carmody got out and opened them just like any ordinary being except that
   he did it with a certain leisurely elegance. Watching his tall figure as
   he paced across, his head held high, the smart hat set at just the right
   angle, I had to admit again that he had enormous presence. It was
   remarkable at his age.
   Shortly before lunch I saw a cow that the farmer had said on the phone
   might have To. "She's gone down t'nick ever since she calved, guvnor. I
   doubt she's a screw, but you'd better have a look at her, anyroad."
   As soon as I walked into the byre I knew what the trouble was. I have
   been blessed with an unusually sensitive nose and the sickly sweet smell
   of ketone hit me right away. It has always afforded me a childish
   pleasure to be able to say suddenly in the middle of a tuberculin test
   "There's a cow in here about three weeks calved that isn't doing very
   well," and watch the farmer scratch his head and ask me how I knew.
   I had another little triumph today. "Started going off her cake first
   didn't she?" and the farmer nodded assent. "And the flesh has just
   melted off her since then ?"
   "That's right," the farmer said, "I've never seen a cow go down as
   quick."
   "Well you can stop worrying, Mr. Smith. She hasn't got TB, she's got
   slow fever and we'll be able to put her right for you."
   Slow fever is the local term for acetonaemia and the farmer smiled in
   relief. "Damn. I'm glad! I thowt she was dog meat. I nearly rang Mallock
   this morning."
   I couldn't reach for the steroids which we use today, but I injected six
   ounces of glucose and 100 units of insulin intravenously - it was one of
   my pet remedies and might make modern vets laugh. But it used to work.
   The cow, dead-eyed and gaunt, was too weak to struggle as the farmer
   held her nose.
   When I had finished I ran my hand over the jutting bones, covered, it
   seemed, only by skin.
   "She'll soon fatten up now," I said. "But cut her down to once a day
   milking - that's half the battle. And if that doesn't work, stop milking
   her entirely for two or three days."
   "Yes, I reckon she's putting it in "'bucket instead of on her back."
   "That's it exactly, Mr. Smith."
   Carmody didn't seem to appreciate this interchange of home-spun wisdom
   and fidgeted impatiently. I took my cue and headed for the car.
   "I'll see her in a couple of days," I cried as we drove away, and waved
   to Mrs. Smith who was looking out from the farmhouse doorway. Carmody
   however raised his hat gravely and held it a few inches above his head
   till we had left the yard, wh:eh was definitely better. I had noticed
   him doing this at every place we had visited and it looked so good that
   I was playing with the idea of starting to wear a hat so that I could
   try it too.
   I glanced sideways at my companion. Most of a morning's work done and I
   hadn't asked him any questions. I cleared my throat.
   "By the way, talking about that cow we've just seen, can you tell me
   something about the causes of acetonaemia?"
   Carmody regarded me impassively. "As a matter of fact I can't make up my
   mind which theory I endorse at the moment. Stevens maintains it is the
   incomplete oxidation of fatty acids, Sjollema leans towards liver
   intoxication and Janssen implicates one of the centres of the autonomic
   nervous system. My own view is that if we could only pin-point the exact
   cause of the production of diacetic acid and beta-oxybutyric acid in the
   metabolism we'd be well on the way to understanding the problem. Don't
   you agree?"
   I closed my mouth which had begun to hang open.
   "Oh yes, I do indeed ... it's that oxy ... that old beta-oxy ... yes,
   that's what it is, without a doubt." I slumped lower in my seat and
   decided not to ask Carmody any more questions; and as the stone walls
   flipped past the w.indows I began to face up to the gradually filtering
   perception that this was a superior befog next to me. It was depressing
   to ponder on the fact that not only was he big, good-looking" completely
   sure of himself but brilliant as well. Also, I thought bitterly, he had
   every appearance of being rich.
   We rounded the corner of a lane and came up to a low huddle of stone
   buildings It was the last call befo 
					     					 			re lunch and the gate into the yard
   was closed.
   We might as well go through," I murmured. "Do you mind?"
   The student heaved himself from the car, unlatched the gate and began to
   brtog it round. And he did it as he seemed to do everything; coolly,
   unhurriedly, with natural grace. As he passed the front of the car I was
   studying him afresh, wondering again at his style, his massive
   composure, when, apparently from nowhere, an evil looking little black
   cur dog glided silently out, sank its teeth with dedicated venom into
   Carmody's left buttock and slunk away.
   Not even the most monolithic dignity can survive being bitten deeply and
   without warning in the backside. Carmody screamed, leaped in the air
   clutching his rear, then swarmed to the top of the gate with the agility
   of a monkey. Squatting on the top spar, his natty hat tipped over one
   eye, he glared about him "What the hell?" he yelled. "What the bloody
   hell?"
   "It's all right," I said, hurrying towards him and resisting the impulse
   to throw myself on the ground and roll about. "It was just a dog."
   "Dog? What dog? Where?" Carmody's cries took on a frantic note.
   "It's gone - disappeared. I only saw it for a couple of seconds." And
   indeed, as I looked around it was difficult to believe that that
   flitting little black shadow had ever existed.
   Carmody took a bit of coaxing down from the top of the gate and when he
   finally did reach ground level he limped over and sat down in the car
   instead of seeing the case. And when I saw the tattered cloth on his
   bottom I couldn't blame him for not risking a further attack. If it had
   been anybody else I'd have told him to drop his pants so that I could
   slap on some iodine but in this instance I somehow couldn't bring myself
   to do it. I left him sitting there.
   Chapter Twenty.
   When Carmody turned up for the afternoon round he had completely
   recovered his poise. He had changed his flannels and adopted a somewhat
   lopsided sitting position in the car but apart from that the dog episode
   might never have happened. In fact we had hardly got under way when he
   addressed me with a touch of arrogance.
   "Look, I'm not going to learn much just watching you do things. Do you
   think I could carry out injections and the like? I want actual
   experience with the animals themselves."
   I didn't answer for a moment but stared ahead through the maze of fine
   cracks on the windscreen. I couldn't very well tell him that I was still
   trying to establish myself with the farmers and that some of them had
   definite reservations about my capabilities. Then I turned to him.
   "OK. I'll have to do the diagnosing but whenever possible you can carry
   on from there."
   He soon had his first taste of action. I decided that a litter of ten
   week old pigs might benefit from an injection of E cold antiserum and
   handed him the bottle and syringe. And as he moved purposefully among
   the little animals I thought with gloomy satisfaction that though I may
   not be all fait with all the small I print in the text books I did know
   better than to chase pigs into the dirty end of the pen to catch them.
   Because with Carmody in close pursuit the squealing creatures leaped
   from their straw bed and charged in a body towards a stagnant lake of
   urine against the far wall. And as the student grabbed at their hind
   legs the pigs scrabbled among the filth, kicking it back over him in a
   steady shower. He did finally get them all injected but at the end his
   smart outfit was liberally spattered and I had to open the windows wide
   to tolerate his presence in the car.
   The next visit was to a big arable farm in the low country, and it was
   one of the few places where they had hung on to their horses; the long
   stable had several stalls in use and the names of the horses on the wall
   above; Boxer, Captain" Bobby, Tommy, and the mares Bonny and Daisy. It
   was Tommy the old cart horse we had to see and his trouble was a
   'stoppage".
   Tommy was an old friend of mine; he kept having mild bouts of colic with
   constipation and I often wondered if he had a faecolith lurking about in
   his bowels somewhere. Anyway, six drachms of Istin in a pint of water
   invariably restored him to normal health and I began automatically to
   shake up the yellow powder in a drenching bottle. Meanwhile the farmer
   and his man turned the horse round in his stall, ran a rope under his
   nose band, threw it over a beam in the stable roof and pulled the head
   upwards.
   I handed the bottle to Carmody and stepped back. The student looked up
   and hesitated. Tommy was a big horse and the head, pulled high, was far
   beyond reach; but the farm man pushed a ramshackle kitchen chair
   wordlessly forward and Carmody mounted it and stood swaying
   precariously.
   I watched with interest. Horses are awkward things to drench at any time
   and Tommy didn't like Istin, even though it was good for him. On my last
   visit I had noticed that he was becoming very clever at holding the
   bitter mixture at the back of his throat instead of swallowing it. I had
   managed to foil him by tapping him under the chin just as he was toying
   with the idea of coughing it out and he had gulped it down with an
   offended look. But it was more and more becoming a battle of wits.
   Carmody never really had a chance. He started off well enough by
   grasping the horse's tongue and thrusting the bottle past the teeth but
   Tommy outwitted him effortlessly by inclining his head and allowing the
   liquid to flow from the far side of his mouth.
   "It's coming out t'other side, young man!" the farmer cried with some
   asperity.
   The student gasped and tried to direct the flow down the throat but
   Tommy had summed him up immediately as an amateur and was now in
   complete command of the situation. By judicious rolling of the tongue
   and a series of little coughs and snorts he kept ridding himself of most
   of the medicine and I felt a pang of pity at the sight of Carmody
   weaving about on the creaking chair as the yellow fluid cascaded over
   his clothes.
   At the end, the farmer squinted into the empty bottle.
   "Well I reckon t'oss got SOME of it," he muttered sourly Carmody eyed
   him impassively for a moment, shook a few ounces of Istin solution from
   somewhere up his sleeve and strode out of the stable.
   At the next farm I was surprised to detect a vein of sadism in my
   makeup. The owner, a breeder of pedigree Large Whits pigs, was exporting
   a sow abroad and it had to be subjected to various tests including a
   blood sample for Brucellosis. Extracting a few c.c."s of blood from the
   ear vein of a struggling pig is a job which makes most vets shudder and
   it was clearly a dirty trick to ask a student to do it, but the memory
   of his coldly confident request at the beginning of the afternoon seemed
   to have stilled my conscience. I handed him the syringe with scarcely a
   qualm.
   The pigman slipped a noose into the sow's mouth and drew it tight over
   the snout and behind the canine teeth. This common method of restrain 
					     					 			t
   isn't at all painful but the sow was one of those who didn't like any
   form of mucking about. She was a huge animal and as soon as she felt the
   rope she opened her mouth wide m a long-drawn, resentful scream. The
   volume of sound was incredible and she kept it up effortlessly without
   any apparent need to draw breath. Conversation from then on was out of
   the question and I watched in the appalling din as Carmody put an
   elastic tourniquet at the base of the sow's ear, swabbed the surface
   with spirit and then poked with his needle at the small blood vessel.
   Nothing happened. He tried again but the syringe remained obstinately
   empty. He had a few more attempts then, as I felt the top of my head was
   going to come loose I wandered from the pen into the peace of the yard.
   I took a leisurely stroll round the outside of the piggery, pausing for
   a minute or two to look at the view at the far end where the noise was
   comparatively faint. When I returned to the pen the screaming hit me
   again like a pneumatic drill and Carmody, sweating and slightly
   pop-eyed, looked up from the ear where he was still jabbing fruitlessly.
   It seemed to me that everybody had had enough. Using sign language I
   indicated to the student that I'd like to have a go and by a happy
   chance my first effort brought a dark welling of blood into the syringe.
   I waved to the pigman to remove the rope and the moment he did so the
   big sow switched off the noise magically and began to nose, quite
   unperturbed, among the straw.
