This contraband medicine, intended for the sick on board, would eventually be sold for a most handsome profit when the ship berthed in Rio de Janeiro. Potbottom also saw to it that some small part of the profit was paid to the hospital matron, a professed Christian, who had a most remarkable propensity to see no evil when to be blind was to her benefit.
It was a foolproof method, for when the medical supplies remaining were checked by the authorities in Hobart Town against the surgeon-superintendent's prescription ledger and subtracted from the amount placed on board at the port of embarkation, the amounts would tally perfectly. If any convict should complain to the authorities that she had not received medication for an illness, the hospital matron would swear that this was a lie. Furthermore, if a member of the crew or prison staff required attention while on board they would be treated most generously with whatever physic was required, so that they would readily testify to the probity of the ship's surgeon and the diligence of its hospital matron.
The dispensary was situated in a small cabin behind a bulkhead at the end of the hospital and Mary, while recovering from the attack on her in the prison, had observed that Potbottom entered it alone each morning, leaving the door slightly ajar. He worked there unobserved and, at the same time, allowed sufficient air into the tiny room which lacked a porthole of its own.
Mary tried to recall every detail of Potbottom's early morning entry. He had never spoken, which was unusual, for his busy cackle was as much a part of him as his quick, nervous movements. He was a prattler of exceptional talent. Yet he would enter the hospital silently and, Mary now realised, in a most agitated state fumble the key into the lock of the dispensary as though he were on a most urgent mission.
However, when some time later he emerged he would be his usual vile self, cackling and quick-tongued, small cruel eyes sparkling as he stood at her berth to say something unpleasant. He would leave the hospital in a fine mood, delighted with himself, eager to embrace the task of making those around him afraid of the consequences of doing anything which might displease him.
Mary's berth had been almost beside the door of the dispensary and on the second morning in hospital Potbottom had entered in an even more agitated state than usual. His arms were clasped tightly across his chest and he shivered as though he were very cold. His tiny claws scratched with great irritation at the topmost part of his arms. Mary observed that his lips were cracked and without colour, a thin line of white spit bubbles stretching the length of his mouth. Feigning sleep, she watched as his hands fumbled to unlock the door to the dispensary. In his haste to enter he left the door somewhat more ajar than usual, and by craning her neck Mary could see into the tiny cupboard-sized cabin.
Potbottom, his hands trembling, quickly mixed an amount of raw opium in a small glass container into which he poured what looked to be a syrup from its distinctive blue bottle. Mary was most familiar with opium, it having come close in the past to taking her life. The syrup she took to be laudanum, a mixture of opium dissolved in alcohol, used by prostitutes on the way down. Only those most heavily addicted would think to use more opium in their laudanum, as she herself had done in that darkest time of her life.
Mary watched as the surgeon's assistant hastily swallowed the liquid and then waited, with eyes closed, for it to hit. She knew exactly how he felt. The jangled nerves suddenly straightened, the tension relaxed and his mind and thoughts once more collected. The muscles of his arms and legs no longer jumped and as his craving body received the devil's tonic the dreadful itching under his skin mercifully melted away.
Mary knew at once that Tiberias Potbottom was a helpless victim of the oriental poppy and, judging from the amount of opium grains he'd mixed with the laudanum, he was greatly dependent upon its effects and well accustomed to its constant use.
As Mary lay in the darkness of the coal hole a plan slowly began to emerge in her mind. She prayed that some small part of all her future luck, the golden luck which now dangled around the little monkey's scrawny neck, might be granted to her on credit. Her prayers were directed at whomsoever cared to hear them, whether God or the devil, she didn't much care.
After her flogging and the week spent in isolation, Mary became the subject of great admiration among the convict women. They had greatly missed Mary reading to them in the hot afternoons and the wry and cryptic comments she made about many of the morally uplifting books the Quakers had so generously supplied. Mary's readings of faraway places and of great journeys undertaken allowed for pictures to grow in their minds. And when she read of the lives of great men, for there were no biographies of women, the prisoners felt as though they too were a part of the grand story of the human race and not merely the scum and sweepings of a society which had rejected them. The children on board would clamour around her the moment she was free from her work, plucking at her skirt. 'Please, Mistress Mary, a story!' they would beg, pestering her until she would relent and gather them around her in a corner of the deck and read to them from Gulliver's Travels or from the books left for children by the Quakers.
Mary would also sometimes talk of the great journey they were themselves making. She would recount it, not as though it were themselves taking part, but as if it had happened to a group of intrepid adventurers cast adrift and sailing at the merciless whim of the winds to the outer reaches of the universe. Mary's story filled them with pride and hope at their own resolve, and told how the women in this strange and magnificent adventure would one day tame a wild land. Their eyes would shine as she envisaged how they would make this wild frontier a safe place for their sons and daughters, who would be free men and women possessed of handsome looks, sturdy of body and mind, prosperous in every circumstance.
Mary had also taken on the task of running the school for those who wished to learn to read and write, and her pupils, including the eleven children on board, had missed her greatly. For while Mary was a strict task mistress, they had almost all progressed and took great confidence from the new light which was beginning to shine within their minds.
Potbottom insisted that Mary still be allocated the most menial of tasks for her morning duties. She persuaded the matron of the prison hospital to allow her to be a cleaner, this being in return for reading religious tracts to the patients for half an hour each day. The matron, Mrs Barnett, readily agreed, as Mary had been prepared to accept the most onerous of tasks, to clean out the water closets and to act as the laundry maid.
Mrs Barnett had no cause to be suspicious as Mary's request was a common one, given that rations for the sick were greatly superior to the food served to the other prisoners and included preserved tinned vegetables and rice. Those prisoners who were fortunate enough to work in the prison hospital would sometimes benefit from the scraps and scrapings left in the pots or on the plates. Or, on a propitious day they might come upon half a mug of beefy broth with golden gobbets of fat swimming on its surface, or a portion of food left by a patient who was too poorly disposed to eat. In contrast to their usual fare, which consisted of salted beef or pork, or a helping of plum pudding, all of which was served with a portion of weevily ship's biscuit, the heavenly taste of an ounce of tender preserved beef, a mouthful of peas or a spoonful of rice gathered a few grains at a time from several plates, was well worth the lowliest task required in the hospital.
