"Ferry well, Sheila, I will do that," he said, knowing well why the girl wished it.

So father and daughter bade good-bye to each other; and Mackenzie went on shore with his face down, and said not a word to any of his friends on the quay, but got into the wagonette, and, lashing the horses, drove rapidly away. As he had shaken hands with Lavender, Lavender had said to him, "Well, we shall soon be back in Borva again to see you;" and the old man had merely tightened the grip of his hand as he left.

The roar of the steam-pipes ceased, the throb of the engines struck the water, and the great steamer steamed away from the quay and out of the plain of the harbor into a wide world of gray waves and wind and rain. There stood Mackenzie as they passed, the dark figure clearly seen against the pallid colors of the dismal day; and Sheila waved a handkerchief to him until Stornoway and its lighthouse and all the promontories and bays of the great island had faded into the white mists that lay along the horizon. And then her arm fell to her side, and for a moment she stood bewildered, with a strange look in her eyes of grief, and almost of despair.

"Sheila, my darling, you must go below now," said her companion: "you are almost dead with cold."

She looked at him for a moment, as though she had scarcely heard what he said. But his eyes were full of pity for her: he drew her closer to him, and put his arms round her, and then she hid her head in his bosom and sobbed there like a child.

THE EMERALD.

Dutens and several others who have written upon gems and precious stones during the last two centuries have asserted that the ancients were unacquainted with the true emerald, and that Heliodorus, when speaking nearly two thousand years ago of "gems green as a meadow in the spring," or Pliny, when describing stone of a "soft green lustre," referred to the peridot, the plasma, the malachite, or the far rarer gem, the green sapphire. But the antiquary has come to the rescue with the treasures of the despoiled mounds of Tuscany, the exposed ashes of Herculaneum and Pompeii, and now exhibits emeralds which were mounted in gold two thousand years before Columbus dreamed of the New World, or Pizarro and his remorseless band gathered the precious stones by the hundred-weight from the spoils of Peru. Although these specimens of antique jewelry set with emeralds may be numbered by the score or more in the museums and "reliquaries" of Europe, but very few engraved emeralds have descended to us from ancient times: This rarity is not due to the hardness of the stone, for the ancient lapidaries cut the difficult and still harder sapphire: therefore we must believe the statement of the early gem-writers that the emerald was exempted from the glyptic art by common consent on account of its beauty and costliness.

The emerald is now one of the rarest of gems, and its scarcity gives rise to the inquiry as to what has become of the abundant shower of emeralds which fairly rained upon Spain during the early days of the conquest of Mexico and Peru, bringing down the value of fine stones to a trifling price. As with all commercial articles, there is a waste and loss to be accounted for during the wear of three centuries, but this alone will not explain their present rarity in civilized countries. Even in the times of Charles II., when the destitution of the country was extreme, the dukes of Infantado and Albuquerque had millions in diamonds, rubies and precious stones, yet hardly possessed a single sou. So impoverished was the land, and so slender were the purses of all, that the duke of Albuquerque dined on an egg and a pigeon, yet it required six weeks to make an inventory of his plate. At this period, when the nobles gave fêtes the lamps were often decorated with emeralds and the ceilings garlanded with precious stones. The women fairly blazed with sparkling gems of fabulous value, while the country was starving. Most, if not all, of this missing treasure was transferred to Asia, and with the silver current which flowed steadily from the Spanish coffers into India went many of the emeralds also; for in those regions this gem is regarded as foreign stone, and the natives, investing it with the possession of certain talismanic properties, prize it above all earthly treasures.

When the Spaniards commenced their march toward the capital of Mexico, they were astonished at the magnificence of the costumes of the chiefs who came to meet them as envoys or join them as allies, and among the splendid gems which adorned their persons they recognized emeralds and turquoises of such rare perfection and beauty that their cupidity was excited to the highest degree. During the after years of conquest and occupation the avaricious spoilers sought in vain for the parent ledge where these precious stones were found. Recent times have, however, revealed the home of the Mexican turquoise, which has proved to be in the northern part of Mexico, as the Totonacs informed the inquiring Spaniards. The first of these mines, which is of great antiquity, is situated in the Cerrillos Mountains, eighteen miles from Santa Fé. The deposit occurs in soft trachyte, and an immense cavity of several hundred feet in extent has been excavated by the Indians while searching for this gem in past times. Probably some of the fine turquoises worn by the Aztec nobles at the time of the Spanish Conquest came from this mine. Another mine is located in the Sierra Blanca Mountains in New Mexico, but the Navajos will not allow strangers to visit it. Stones of transcendent beauty have been taken from it, and handed down in the tribe from generation to generation as heirlooms. Nothing tempts the cupidity of the Indians to dispose of these gems, and gratitude alone causes them to part with any of these treasures, which, like the mountaineers of Thibet, they regard with mystical reverence. The Navajos wear them as ear-drops, by boring them and attaching them to the ear by means of a deer sinew. Lesser stones are pierced, then strung on sinews and worn as neck-laces. Even the nobler Ute Indians, when stripping the ornaments of turquoise from the ears of the conquered Navajos, value them as sacred treasures, and refuse to part with them even for gold or silver.
