IT was a dark night of storm and wind, but the people in the little farm on the western coast of Scotland were accustomed to stormy winds and the sound of breakers dashing upon the rocky shore, and they paid little heed to the wintry weather. They were all tired out with their day's work, and thankful, when the darkness closed in, to bar the doors and shut out the wild night as they gathered round the fire within. A rough set of people they looked in the light of the great peat fire that burned on the hearth. Only one, a boy of sixteen, seemed different to the rest, and had a gentler, more civilised look, while he held himself as if accustomed to command.
This boy was Patrick, son of the master Calponius, who belonged to the Roman colony at Dumbarton, and he had been brought up with care and taught all that a young Roman citizen should know. His gentle mother, niece of the holy Saint Martin of Tours, had brought with her many a cherished memory of courtly manners from the sunny land of her birth, and she had taught the boy to be courteous and knightly in his bearing. So it was that Patrick learned many things which were as yet unknown in the savage northern land  where he dwelt, but chiefest among all was the faith of Christ, taught to him by his father and mother, who were both Christians.
But all these lessons seemed very dull and uninteresting to the restless boy. It was such a waste of the golden hours to sit indoors and learn those endless psalms. Prayers, too, took such a weary time, when he might be out on the hillside, as free as the happy birds and all the wild creatures that lived under the open sky. Sometimes in his heart he almost wondered whether it might not be pleasanter to be a heathen rather than a Christian. The heathen had no psalms to learn and could do just as they pleased.
"Some day thou wilt grow wiser," said his mother, "and what is but a dull lesson to thee now will be like apples of gold in pictures of silver."
But Patrick could not understand what she meant, and he was only too glad when lesson-time was over and he was allowed to go off to the little farm close to the sea, where he could work with his hands and not with his head. How he loved the rough free life there; the days spent in the fields and woods, the evenings when the peat was heaped high on the glowing hearth, and he listened to the stories of brave deeds and wild adventures which were told or sung in the flickering firelight! What cared he for shrieking winds and the roar of the breakers outside? It was fitting music to echo around the splendid tales that made his heart beat like a drum and his eyes glow like the fire.
 "It is a wild night," said one of the men, "and black as the pit. We must needs have a wild song to match the night and chase away the blackness."
So the rude chant of savage deeds and wild adventures was taken up one by one, until the roar of the storm was drowned in their ears and the wail of the wind became part of the mournful music.
But outside in the blackness the wind had sterner work to do than to act as chorus to idle tales. What were those mysterious long black boats that fought their way so stubbornly through the angry waves? They seemed like phantoms of the night, so silently they moved, showing never a glimmer of light from stem to stern. In vain the icy wind swept down upon them and strove to beat them back. Slowly but surely they crept on until they reached a sheltered bay where sand was smooth and it was safe to land.
Black and silent as their boats the pirate crew landed one by one, and, like the ghosts of sea-monsters, crawled stealthily over the rocks and up the hill towards the farm that nestled in a hollow there. The light from the peat fire shone through the little window; a burst of wild song came floating out into the dark night: there was no thought of lurking danger or surprise.
Closer and closer crept the black figures until they too could listen to the story that was chanted by the fireside, and they laughed aloud to hear such brave words coming from the lips of men who sat safe and warm within, little dreaming of the real danger that beset them without.
 "Hark!" cried one of the singers suddenly, "surely the wind hath a strange voice to-night. To me it soundeth like the laughter of demons."
With one accord the company started to their feet, for the sound they heard was no voice of the storm. The door was burst inwards with a tremendous crash, and well might the little company think for a moment that demons were abroad. Fearlessly and bravely they fought, but one by one they were overpowered, and either killed outright or bound hand and foot. The captain stood and looked at the row of sullen captives.
"Away with them to the boats," he cried. Then, pointing to Patrick, he added, "See that ye handle that one carefully, for he is a strong lad and will fetch a good price when we land on the other side."
There was nothing to be done, no rescue to hope for, and resistance only made matters worse. Patrick lay stunned and despairing in the bottom of the boat which was to carry him away from his home and his friends. It was all like a bad dream, the tossing of that stormy sea, the long dark night, the landing in a strange country, and the knowledge that he was now a slave to be sold to the highest bidder.
So Patrick came to Ireland, and was sold to a man whom they called Michu, and sent out into the fields to feed his master's swine.
Strong and hardy as the boy was, the life which he had now to lead taxed his endurance to the uttermost. There was little rest or leisure, for a  slave's work is never finished, and he was often so hungry and so bitterly cold that he felt half stunned with misery. Even when the snow was on the ground he had to drive out his herd of pigs to find food for them, and often he was out all night upon the hillside, sheltering in some rocky corner as best he could from the biting wind that swept over the mountains.
In those long dark nights there was plenty of time for thinking, and the boy's thoughts were always of the far-off home and all that he had lost. Strangely enough it was not of the happy careless hours that he dreamed, but rather of the times that had once seemed so tiresome and so long. He loved to think of his mother, and those dull lessons which had once made him so impatient. Little by little all that he had learned came back to him, but instead of being only tiresome lessons, the psalms and prayers held a curious comforting message, as if a friend were speaking to him. Then their meaning became clearer and clearer until he realised that they were indeed a message from a real Friend. Though he was alone, homeless and utterly friendless, God was still there.
"Our Father," said the boy to himself, and the very words seemed to change everything around. God was here in this terrible unknown country, and God was his Father. To be a slave lost half its bitterness when he could stand upright and know himself to be God's servant as well.
For six long years Patrick served his master, Michu, diligently and well, for all this time he was  learning also to serve God. With that love in his heart, he learned to care for all helpless things, and to see what was beautiful in common things around. Years afterwards, when he was a great teacher and the heathen priests scoffed at his teaching, and asked how he could explain the Trinity "Three Persons in One God," Patrick stooped down and plucked a leaf of the little green shamrock, which had taught him one of his lessons on the lonely hillside, and, showing its three leaves in one, gave a simple illustration of the great Mystery.
It was at the end of his sixth year of slavery, that one night Patrick drove his pigs to a distant hill overlooking his master's farm, and there, under the stars, in the shelter of a rock, he lay down to rest. It was not long before he fell asleep; but in his sleep he heard a voice close at hand speaking to him.
"Thy fasting is well," said the voice; "thou shalt soon return to thy country. Behold a ship is ready for thee, but thou must journey many miles."
Patrick started up, never doubting for a moment but that this was the message of an angel. He had lived so close to God that he was ever ready to receive His commands. In the story of his life, which he has written himself, he says, "I went in the power of the Lord, who directed my way for good, and I feared nothing until I arrived at that ship."
Weary, footsore, and worn after the long journey on foot, Patrick presented himself before the ship's captain, and prayed that he might be taken  aboard and carried over to Britain. It was perhaps small wonder that the captain looked with suspicion at the wild figure of the runaway slave, and bade him angrily begone.
It was a bitter ending to Patrick's hopes, and he turned very sorrowfully away. The journey had been so long, and he had felt so sure that all would be well at the end. Then, as ever, his first thought was to turn to his One Friend, and so he knelt down on the shore and prayed for help and guidance. The answer came even as he prayed, and he heard a shout from one of the sailors, who had followed him.
"Come along," he cried, "they are asking for thee."
Back went Patrick in all haste, and found that meanwhile the captain had changed his mind.
"Come, we will take thee on trust," he said, meaning that Patrick should work out his own passage, or repay him when they landed. "We are about to sail, and hope to reach land in three days."
Those were three days of great happiness to Patrick, as he saw Ireland growing fainter and fainter in the distance, and knew that before him lay freedom and home, and all that he had lost.
But although the ship reached land in three days, it was not the land he knew, and he was still far off from home. The crew of the ship landed somewhere on the coast of Brittany, and tried to find their way to some town, having to travel across a strange, desolate country where there were no  inhabitants and nothing to guide them. Day by day their store of food grew less, until they had nothing left to eat, and it seemed as if they must die of starvation.
Now the captain had found that Patrick was to be trusted, and had watched him often at his prayers, and came to think there must be some truth in a religion that made a man so honest and ready to do his duty. So now he called Patrick to him to ask his advice.
"Christian," he said, "thy God is powerful; pray for us, for we are starving."
"I will pray," answered Patrick, "but thou too must have faith in the Lord."
So just as a hungry child turns to his father and asks for bread, Patrick knelt and prayed to God, and suddenly there was a sound of rushing and tearing through the wood, and a herd of wild boars came sweeping along. The men gave chase, and soon captured and killed enough to provide food for many days.
After many adventures Patrick at last reached home, and for a while forgot all the hardships he had endured in the joy and happiness of that wonderful home-coming.
But the careless happy days of boyhood were over now, and a man's work was waiting for him.
"Only let the work be here," prayed his mother. "O my son, promise that thou wilt never leave us again, now that we have so wonderfully found thee."
For a while that too was Patrick's only wish,  never to leave the dear home and those he loved so well.
But, as he lay asleep one night, the heavenly messenger came once more to him and pointed out the path which God would have him tread. It seemed to Patrick that the angel held in his hand a bundle of letters, and on one was written "the voice of the Irish." This he gave to Patrick, who, as he read, seemed to hear the call of many voices echoing from the land where he had been a slave. Even the voices of little children rang in his ears, and all of them were calling to him and saying, "We entreat thee, come and walk still in the midst of us."
The thought of those poor untaught people who had never heard of God had often made him long to help them, and this call decided him. He would enter God's service as a priest, and then go back to the country of his captivity to carry the torch of God's love in his hand, and spread abroad the glorious light in every corner of the dark land.
After a long time of preparation and study, Patrick was at last consecrated bishop, and then set out at once to return to the country where he had suffered so much.
It was a very different coming this time to the arrival of the boy-slave many years before. With his train of clergy and helpers, the bishop, pastoral staff in hand, landed on the sandy shore of Strangford Lough, and he bore himself as a conqueror marching to victory.
Strangely enough, the first person to greet the band of strangers was a swineherd guarding his pigs,  just as Patrick had done in those long years of slavery. The lad was terrified when he saw these strange men, and although Patrick spoke kindly to him in his own tongue, the swineherd fled away to the woods. With all haste he returned to his master, Dichu, and told his news.
"There are pirates landing at the bay," he cried, "strange men who come to rob and kill."
Dichu in alarm immediately armed himself and his followers and set out to meet the enemy. But instead of the savage pirates he expected, he found a band of peaceful unarmed men, with one at their head whom it was easy to see was no robber.
Patrick came forward then to meet the chief, and the two men talked a while earnestly together.
"Put up your weapons," cried Dichu, turning to his followers, "these men are friends and not enemies."
As friends, then, Dichu led them to his house and made them welcome. The fearless bravery of Patrick and his strong kind face had won the chieftain's heart, and he prepared to entertain him royally. But Patrick could neither rest nor eat until his message was delivered, and as Dichu listened to his burning words, they seemed to seize him with a strange power and made him long to hear more. Gladly would he have kept Patrick with him, but there was much work to be done, and the bishop wished first of all to seek out his old master Michu, and pay the money due to him as the price of the runaway slave.
How well he knew every step of the way to the  old farm! It seemed as if he must be walking in a dream, that he must be still the barefooted, hungry, ill-clad boy of long ago. There were the woods through which he had so often driven his pigs, the banks where he had found the first spring flowers, the rocks which had so often sheltered him, the little green friendly shamrock which he had loved so dearly. Up the steep hillside he climbed, and at the top he paused and knelt in prayer, remembering the vision he had seen there and the message of the angel. Then, rising up, he looked eagerly towards the spot where his master's farm nestled in the hollow beneath.
Alas! he had come too late; nothing but a thin grey curl of smoke marked the place where the smouldering ashes of the farm lay, and, saddest of all, his master too had perished in the fire.
So there was naught to do but turn back and carry the message to others. But Patrick's heart was sad for his old master.
