base to the summit, are rows of buildings, each succeeding row being shorter than the one below it, till at the top sufficient space is left only for a single building which overlooks all the others. These buildings are all small, and nearly of uniform size, each consisting of a single apartment. The walls are constructed of irregular blocks of granite cemented together, and the front walls are all pierced with loop-holes, both near the floor and about five feet above. The floors are of cement, and are on a level with the top of the wall of the building in front. Each building is provided with a large earthen jar, sunk below the floor, capable of holding from thirty to forty gallons. These were probably used for storing water. A short distance from this old town is a small fertile valley, watered by streams from the Andes, while the rest of the country for many leagues round is entirely destitute of vegetation." Such, it is obvious, can only illustrate to us the ruder arts and domestic habits of an outlying settlement in an exposed situation remote from the centres of highest Peruvian civilisation. But the most enduring memorials of Inca sovereignty are those associated with the construction and maintenance of the great public roads, post-houses, and telegraphic corps, by means of which a coherent unity was preserved throughout the singularly diversified regions of the vast empire. "Of the great artificial roads," Mr. Blake notes, "that which leads from Quito to Cuzco, and thence southward over the valley of the Desaguadero, is the most extensive. It is constructed of enormous masses of porphyry, and is still perfect in many parts. Where rapid streams were encountered, suspension bridges were constructed by means of ropes formed of fibres of the maguey. Some of these bridges exceeded two hundred feet in length, and so well did this kind of bridge answer the purpose for which it was designed, that it was adopted by the

Spaniards, and to this day affords the only means of crossing many rivers both in Peru and Chili. The remains of one of these great roads are still to be seen in the most barren and uninhabitable part of the desert of Atacama, as also the tambos, or houses for rest, erected at intervals throughout the whole length for the accommodation of the Inca and his suite. Numerous canals and subterranean aqueducts were formed to conduct the waters of lakes and rivers for irrigating the soil. Some of these have been preserved, and are still used by the Spaniards. One in the district of Condesuyer is of great magnitude, more than four hundred miles in length; but these great works, like the roads, were not confined to the more fertile parts of the country. In the southern part of Peru, and in the midst of the desert, extensive and numerous tunnels were excavated horizontally in sandstone rock, through which the water still runs, and is conducted into reservoirs from whence it is taken to the various gardens of Pica; producing in this arid and desert land one spot which, in the luxuriousness of its vegetation, is rarely found surpassed in places the most favourably situated for cultivation."

A diversity of construction is found in various of those aqueducts and other erections, indicating an intelligent skill in adapting the resources of the locality to the exigencies of the works. Some of the aqueducts, such as that in the valley of Nasea, are constructed of large blocks of masonry, while others, like the one which conveyed the waters of the spring of Amiloe to the city of Tenochitlan, are formed of earthen pipes. But such works not only exhibit diverse adaptations of engineering art to the special circumstances of the structure, they illustrate the skill of very different eras; and while they survive to shame the scepticism of modern critics as to the marvellous native civilisation of Peru, they also, as

in some of the ruined works around Lake Titicaca, point to the memorials of centuries to which the Peruvians themselves looked back as an ancient and half-forgotten past in the days of the Incas. On the shores of Lake Titicaca, extensive ruins still remain, which are believed to have been in the same condition at the date of the Conquest, and to have furnished the models of that architecture with which the Incas covered their wide. domains. Valueless as much of the Mexican chronology is, their mode of recording events gave some definite hold on the chronicles of the nation; whereas the system of Peruvian quipus, under their quipucamayus, or keeper, could have transmitted accurate records, at the most, only to a few generations, and render valueless the pretended history of the dynasty of Manco Capac. In the megalithic character of their architecture, however, the elements of a self-originated and primitive art are strikingly apparent. It is one of the most characteristic features pertaining to the development of human thought in the earliest stages of constructive skill. There seems to be an epoch in the early history of man, when what may be styled the megalithic era of art develops itself under the utmost variety of circumstances. In Egypt, it was carried out with peculiar refinement by a people whose mastery of sculpture and the decorative arts, proves that it had its origin in a far deeper source than the mere barbarous love of vast and imposing masses. In Assyria, India, Persia, and throughout the Asiatic continent, this taste appears to have manifested itself among many and widely severed races; and in northern Europe and the British Isles its enduring memorials are seen in such rudely massive structures as Stennis and Stonehenge. The same mental condition finds expression in the pyramidal terraces and vast temple façades of Central America and Yucatan, and is more fully present in the

massive solidity of Peruvian masonry. It is the uncon scious aim at the expression of abstract power, which attests its triumphs in such barbaric evidence of difficulties overcome; and although it fails even to strive after the beautiful, it not unfrequently impresses us with a sense of sublimity in the very embodiment of that power by which it was achieved.

In this respect the most ancient architectural remains of the southern continent have a higher ethnological value than those of Mexico, Central America, or Yucatan; for they reveal to us the only truly primitive and apparently self-originating architecture of the New World and, therefore, suggest a possible centre from whence that intellectual impulse went forth, pervading with its elevating and refining influences the nations who were first discovered, by the European adventurers of the sixteenth century, on the mainland of America; although at that date the distinct centres of Mexican and Peruvian arts were in operation wholly independent of each other, and had moved in opposite directions, unconscious of the rivalry thus carried on in the development of a native civilisation for the nations of the Western Hemisphere.

CHAPTER XVIII.

THE CERAMIC ART: POTTERY.

AMONG the primitive arts, in which the first rude requirements of primeval man were supplemented by evidences of taste and skill, the plastic or ceramic art merits, on many accounts, a foremost place. The plasticity of the potter's clay, which furnishes so many beautiful and striking metaphors of the Hebrew Scriptures, supplied a means whereby the varying phases of rudimentary national art, and the peculiar habits and tastes of diverse races, could perpetuate the minutest traits of intellectual development. The delicate shades of variation which give individuality and local character to tribes and national subdivisions, are scarcely more minute or expressive than those which the plastic clay has received from the potter's hand, to perpetuate local habits and tastes. On the plains of Shinar, the fathers of the undeluged world wrought and burnt the clay where still some of the most remarkable chronicles of early Asiatic civilisation are recovered, including their cuneatic bricks and cylinders, eloquent with a definite written history. Egypt, too, had her sun-dried bricks and pottery of diverse forms; in working which the Egyptian taskmasters made the lives of their Hebrew serfs bitter with hard bondage, in mortar and in brick. These sun-dried bricks, which in the humid climates of temperate zones would perish in a few seasons, survive amid the sculp tured granite and limestones of ancient Egypt, with the
