Leaving Kabutri in Kalua's cart, Deeti headed alone towards the factory's entrance, nearby. Here stood the weighing shed to which the farmers of the district brought their poppy-leaf wrappers every spring, to be weighed and sorted into grades of fine and coarse, 'chandee' and 'ganta'. This was where Deeti would have sent her own rotis, had she accumulated enough to make the trouble worthwhile. Around harvest time there was always a great press of people here, but the crop being late this year, the crowd was relatively small.

A small troop of uniformed burkundazes was on duty at the gate, and Deeti was relieved to see that their sirdar, a stately white-moustachioed elder, was a distant relative of her husband's. When she went up to him and murmured Hukam Singh's name, he knew exactly why she had come. Your husband's condition isn't good, he said, ushering her into the factory. Get him home quickly.

Deeti was about to step in when she glanced over the sirdar's shoulder, into the weighing shed: the sight made her pull back, with a sudden start of apprehension. Such was the length of the shed that the door at the far end looked like a distant pinprick of light; in between, arrayed along the floor, stood many gigantic pairs of scales, dwarfing the men around them; beside each set of scales sat a tall-hatted Englishman, overseeing teams of weighmen and accountants. Buzzing busily around the sahibs were turbaned muharirs bearing armloads of paper and dhoti-clad serishtas with thick registers; swarming everywhere were gangs of bare-bodied boys carrying improbably tall stacks of poppy-flower wrappers.

But where to go? Deeti said to the sirdar, in alarm. How will I find my way?

Go straight through this shed, came the answer: and keep on going, through the weighing hall, to the mixing room. When you get through, you'll find one of our relatives waiting. He works here too: he'll show you where to find your husband.

With her sari draped over her face, Deeti stepped in and made her way past columns of stacked poppy-flower rotis, ignoring the stares of serishtas, muharirs and other lesser carcoons: not another woman to be seen, but no matter – everyone was too busy to ask where she was going. Yet, it still took an age to reach the far door and here she stood blinded for a moment, in the bright sunlight. Facing her was a doorway, leading into another immense iron-roofed structure, except that this one was even bigger and higher than the weighing shed – it was the largest building she had ever seen. She walked in, murmuring a prayer, and was brought again to a halt by the sight ahead: the space in front of her was so vast that her head began to spin and she had to steady herself by leaning against a wall. Bars of light were shining through slit-like windows that stretched from the floor to the roof; enormous square columns ran down the length of the hall and the ceiling soared so high above the beaten floor that the air inside was cool, almost wintry. The earthy, sickly odour of raw opium-sap hung close to the ground, like wood-smoke on a chilly day. In this hall too, gigantic pairs of scales stood against the walls, here used for the weighing of raw opium. Clustered around each set of scales were dozens of earthenware gharas, of exactly the kind she herself used in packing her harvest. How well she knew them, those vessels: they each held one maund of raw opium gum, of a consistency such that a ball of it would stick briefly to your palm if you upended it. Who would guess, in looking at them, how much time and trouble went into the filling of these vessels? So this was where they came, these offspring of her fields? Deeti could not help looking around in curiosity, marvelling at the speed and dexterity with which the vessels were whisked on and off the scales. Then, with paper battas attached, they were carried to a seated sahib, who proceeded to poke, prod and sniff their contents before marking them with a seal, allowing some through for processing, and condemning others to some lesser use. Nearby, held back by a line of lathi-carrying peons, stood the farmers whose vessels were being weighed; alternatively tense and angry, cringing and resigned, they were waiting to find out if their harvests for the year had fulfilled their contracts – if not, they would have to start the next year with a still greater load of debt. Deeti watched as a peon carried a slip of paper to a farmer and was rebuffed with a howl of protest: all over the hall, she noticed, there were quarrels and altercations breaking out, with farmers shouting at serishtas, and landlords berating their tenants.

Deeti saw now that she was beginning to attract attention, so she hunched her shoulders and stepped forward, hurrying through that endless cavern of a hall, not daring to pause till she found herself outside again, in the sun. Here, she would have liked to linger a little, to catch her breath, but from the cover of her sari she spotted an armed burkundaz striding in her direction. There was only one way to go – into a shed to her right. She did not hesitate; hitching up her sari she stepped quickly through the door.

Now once again Deeti was taken aback by the space ahead, but this time not because of the vastness of its dimensions, but rather the opposite – it was like a dim tunnel, lit only by a few small holes in the wall. The air inside was hot and fetid, like that of a closed kitchen, except that the smell was not of spices and oil, but of liquid opium, mixed with the dull stench of sweat – a reek so powerful that she had to pinch her nose to keep herself from gagging. No sooner had she steadied herself, than her eyes were met by a startling sight – a host of dark, legless torsos was circling around and around, like some enslaved tribe of demons. This vision – along with the overpowering fumes – made her groggy, and to keep herself from fainting she began to move slowly ahead. When her eyes had grown more accustomed to the gloom, she discovered the secret of those circling torsos: they were bare-bodied men, sunk waist-deep in tanks of opium, tramping round and round to soften the sludge. Their eyes were vacant, glazed, and yet somehow they managed to keep moving, as slow as ants in honey, tramping, treading. When they could move no more, they sat on the edges of the tanks, stirring the dark ooze only with their feet. These seated men had more the look of ghouls than any living thing she had ever seen: their eyes glowed red in the dark and they appeared completely naked, their loincloths – if indeed they had any – being so steeped in the drug as to be indistinguishable from their skin. Almost as frightening were the white overseers who were patrolling the walkways – for not only were they coatless and hatless, with their sleeves rolled, but they were also armed with fearsome instruments: metal scoops, glass ladles and long-handled rakes. When one of these overseers approached her she all but screamed; she heard him say something – what it was she did not wish to know, but the very shock of being spoken to by such a man sent her scurrying down the tunnel and out at the far end.

Not till she was through the door did she allow herself to breathe freely again: now, as she was trying to cleanse her lungs of the odour of raw, churned opium, she heard someone say: Bhauji? Are you all right? The voice proved to be that of their relative and it was all she could do not to collapse on him. Fortunately, he seemed to understand, without explanation, the effect the tunnel had had on her: leading her across a courtyard, he stopped at a well and poured water from a bucket, so she could drink and wash her face.

Everyone needs water after they come through the mixing room, he said. Better you rest here a bit, Bhauji.

Gratefully, Deeti squatted in the shade of a mango tree while he pointed to the buildings around them: there was the wetting shed, where the poppy-leaf wrappers were dampened before being sent into the assembly room; and there, set a little way back from the other buildings, was the house where medicines were made – all kinds of dark syrups and strange white powders that were much valued by the sahibs.
