But a difficulty arose. He was unwilling, at least at first, to ask his bride to exchange the comparative quietude of her father's home for the restless life of a ship of war. In dire perplexity he sought the advice of his friend the saint of Isle Maree. The wise old man proposed that another and a larger dwelling should be erected in the form of a tower to the west of the enclosure in the centre of which stood his own humble cell. To this tower Olaf might bring his bride and there they might take up their abode, within easy reach of the prince's galley on Loch Ewe. To hasten on. The prince eagerly adopted this plan, and in a short time the tower was built, and Olaf brought his bonny bride to the island. Here they were married by the aged hermit, amid the rejoicings of their followers. The princess and her maidens were delighted with the romantic and secure retreat. Olaf's attendants pitched their tents around, and the leafy grove grew gay with joyful laughter and with genial song. For a while all went smoothly. The life of the young lovers was a continual delight; their passion for one another only increased as months rolled on. In vain his comrades sent message after message entreating the presence of the prince on board his ship. He could not tear himself away from his darling, and she in turn was more than unwilling that he should leave her. At length there came word that a long-planned expedition, in which other leaders were to take part, was ready to start, and Olaf was expected to assume the command. He dared no longer remain in retirement. With aching heart he told the princess of his approaching departure. Her tears were unavailing; on the morrow he must leave. Meanwhile strange forebodings of evil filled the minds of both. What if he should be slain in battle! What if some unknown danger should cause her death in his absence! A scheme was concocted for shortening the final moments of suspense. It was agreed that when the prince should return, a white flag would be displayed from his barge on Loch Maree if all were well; if otherwise, a black flag would be shewn. The maidens prepared these flags, and the prince took them with him. The princess was to leave the island in her barge whenever her lord's boat should come in sight, and she in like manner was to display a white or black flag to denote her safety or the reverse. The morning came, and they parted. The prince arrived at Poolewe, was received by his men with wild enthusiasm, and set sail at once. It is not necessary that we should follow him through the perilous campaign. Enough that all ended well, and the victorious prince returned safely to Poolewe. In hot haste, and half crazy with excitement, he sought his boat on Loch Maree, raised with his own hand the snow-white banner of success, and mustered the faithful attendants who were to row him to Isle Maree.
