second story is usually composed of a wooden frame-work, upon both sides of which canes are nailed, or fastened by leather thongs, and the whole is then plastered over, and painted to imitate stone, the deception being aided by the apparent massiveness of the construction. The division walls are also made of canes plastered over. The roofs are flat, composed of rafters, covered with mats or cane, with a layer of clay spread above them, sufficient to exclude the rays of the sun and the heavy dews. A single prolonged shower would be sufficient to dissolve the whole city; but as it never rains there, these slight walls and roofs are all that is required. Lima is justified in placing her dependence in architecture upon a reed, rather than upon stone. The more solid and massy the walls, the less protection do they afford against the terrible earthquakes which are of periodical occurrence, and by which more than once the city has been reduced to a heap of ruins; while these light cane fabrics yield to the shock, and when it has passed resume their places, with little apparent injury; and even if demolished they do not occasion that fearful peril of life which results from the overthrow of more stable fabrics. There are few places the inhabitants of which present so great a diversity of complexion and physiognomy as in Lima. There is every gradation and intermixture of race, from the fair Creoles of unmixed European descent, who pride themselves upon the purity of their Spanish blood, to the jet black negro of Congo, whose unmitigated ebony hue bears testimony equally unequivocal to his pure African lineage. Between these two extremes is an almost innumerable variety of mixed races, each having its own peculiar designation, indicating the precise proportion of European, Indian, and negro blood in their veins, each marked with its own peculiar physical, intellectual, and moral characteristics; and each finding its chief boast in the nearness of its relation to the white race, and looking down with contempt upon those a shade darker than its own. [Illustration: PERUVIAN CAVALIER.] In 1836, when the population of the city was a little more than 54,000, it was composed of about the following proportion of the different races: white _Creoles_, all of European, and mostly of Spanish descent, 20,000; _Negroes_, 10,000; of whom a little less than one half were slaves; Indians, 5000; mixed races, 19,000; these are of every shade of complexion, from the _Mestizo_, the child of a white father and an Indian mother, whom only a keen and practiced eye can distinguish from a White, and to whom no higher compliment can be paid than to inquire whether he is not a Spaniard, to the _Zambo_ who can only show claim to a portion of white blood, on the ground that to all the vices of the negro race, he adds others peculiar to the Whites.
