Through Spain and Portugal, every object of interest was photographed, from the wild and thrilling scenery of the Pyrenees in the north to that bold headland rock of Gibraltar in the south, and from the calm Mediterranean in the east to the turbulent waters of the Atlantic on the west. Of Switzerland, we exhibit its snow-capped peaks of perpetual ice and snow; Mont Blanc, Matterhorn and Jungfrau; its placid lakes; mountain passes, like shelves cut in rock; its bridges of ice and variety of wild scenery that is seen nowhere but in Switzerland. Through sunny Italy we gathered photographs from lakes Lugano, Maggiore and Como with perpetual spring, in the north, to the fiery crater of Mount Vesuvius in the south; Venice, the "Queen of the Adriatic;" Genoa, the home of Columbus; Pisa, its leaning tower; Florence, the "flower of cities," with its galleries of statues and paintings that the wealth of nations could not purchase; and Rome, that mighty city by the Tiber, that once ruled the world, and is still the abode of the Pope; St. Peters and its ruins; yet now calm, peaceful and powerless. Austria, where the Catholic bows his head to every shrine, favored us with its sublime mountain scenery; the picturesque Tyrol; the blue Danube, famous in history and song; and Vienna, the home of the Emperor and the former abode of Maria Theresa, strangely fascinating and unlike any other city in the whole world. Turkey, the land of the Sultan and the followers of Mahomet, with its strange people and curious habits, is represented by Constantinople, with its mosques and minarets, from the top of which the Mussulman sings out his daily calls for prayer, Ali! Ali!--there is but one God, and Mahomet is his prophet; its streets, gates and squares; the Bosphorus and Golden Horn. Classic Greece, once the centre of art and learning, adorns our collection with Athens, the Acropolis and Parthenon, the latter almost completely and shamefully bereft of those famous marbles, chiseled by Phidias nearly five hundred years before Christ. In ancient Egypt we photographed the Suez Canal; Alexandria, the former city of Cleopatra; Cairo, the home of the Khedive and his harems; the Sphynx and Pyramids, the latter the tombs of the selected Ptolemies; the river Nile, fed by the melting snows from the mountains of the Moon, and pouring its waters over this ancient valley with a regularity as though the ruined temples on its banks give it command. Palestine, the Holy Land, made famous in the history of the Christian Church, added Jeruselem, the City of David; Bethlehem, the cradle of Christ; Jordan, where He was baptized; the Sea of Galilee, on whose shores He preached to the multitude; Nazareth, from which He was called a Nazarene; Gethsemane, where He suffered; Calvary, where He was crucified.
