BRIDGE OF ATTOYAC.

From Cordoba to Paso del Macho the fine scenery continued, the train winding among hills and mountains, disappearing into tunnels, crossing deep valleys upon graceful bridges, and steadily unfolding a panorama of great beauty. Frank made note of the bridge of Attoyac, 330 feet long; the Chiquihuite bridge, 220 feet long; and that of San Alego, three miles before reaching Paso del Macho, which is 318 feet long. In twenty miles there was a descent of 1200 feet, and the scenery steadily assumed more and more a tropical aspect.

But beyond Paso del Macho the country changed again and grew sterile, as though they were once more in the region of the tierra fria.

"How is this?" queried Fred. "Here we are coming all the time nearer the sea both in elevation and distance; I thought we should have it a perfect forest of tropical growths all the way to Vera Cruz."

IN TIERRA CALIENTE.
