Photo by Hiram Bingham INGENIOUS STONE-FITTING: MACHU PICCHU A section of the ornamental wall, showing how ingeniously the joint was made with the next house wall, so as to form a brace which would prevent the house and ornamental wall from leaning apart. Notice the exquisite precision with which each block, after all these centuries in a land where earthquakes are not uncommon, fits snugly into its neighbors. There is no cement nor mortar, and yet there is scarcely a place where a pin can be driven between the stones.

The tiers of stones gradually decrease insize toward the top of the wall. The utmost care was exercised inselecting the purest white granite, so as to produce aneffect like that ofthemarble temples in the Old World (seepage 471).
