"You are mistaken," I replied.

"How is it then that you gentlemen speak such good Castillian. You speak it much better than I do."

"I learned it in Spain," I answered. "The señor with me is a Spaniard."

"Ah, I understand," answered the official. I could see by his amazed and ignorant look that he did not understand but was unwilling to have us know the extent of his ignorance.

"We are in a hurry to be on our journey to Moquegua; you had better return the passport," I said as I tendered him two silver pieces of the one sol denomination, the standard monetary unit of Peru. A sol is worth fifty cents.

"Mil gracias, señor, mil gracias," answered the official thanking me profoundly. Prat, who had ridden on, now turned back and wanted to know what was delaying me. He was on the point of letting off steam anew at the cholo, but upon seeing me give him a tip, he threw a piece of silver on the ground at the fat official's feet. It was comical to see the latter grovel in the dust to pick it up.

"Adios, señores," he yelled after us as we spurred our horses into a gallop and were soon lost to sight.

Upon our reaching the top of a high, barren hill, a vista of a parched and sandy, barren imitation of the Sahara unveiled itself before us. Everywhere lay the bones of oxen and mules. This was the horrible desert of Pampa Zorra about twenty miles wide, which it took us over four hours to cross, in a hot, desiccating, blazing sun. The thermometer must have been in excess of 120 degrees Fahrenheit. With our eyes smarting with dust and our throats parched (we partook sparingly of the water from our canteens), we arrived shortly after midday at a dry ravine named the Coari. Following this downwards between high hills of shale rock we came in half an hour to the Curibaya River at the cluster of mud huts and ranch house of Coari. Here were some green fields of alfalfa surrounded by eucalyptus trees.

The Curibaya River is much like the Sama, only its river bed is narrower. It also has more water, there being plenty to wet one's feet in. The reason for this is that cultivation does not extend as high in its bottom as in the Sama so less is drawn off for irrigation. About twenty miles below Coari it widens out into a broad valley of great fertility; most of its water is used at that point to supply the large vineyards in that neighborhood. The small remainder loses itself in the sand and never reaches the ocean excepting during times of cloudbursts in the mountains. In the fertile valley is the small city of Locumba, which is famous for its grapes and wines said to be the best in Peru. We forded Curibaya before we reached Coari and then turned eastward again, ascending the valley. This soon forked the Ilabaya joining it from the north. The latter is a swiftly rushing and jumping rivulet; our trail lay up its defile and we must have crossed it two dozen times in the eight miles that it took us to reach the town of the same name which is situated in a high open valley, surrounded on all sides with hills not entirely devoid of vegetation. The landscape instead of being sandy was rocky and abounded with gray boulders. There were several varieties of cactus and a plant not unlike the yucca.

Ilabaya is a typical town of the coastal region of Peru, differing greatly from Andean cities in so far that the houses were all built of adobe. The roofs instead of being of mud, were tiled, because it rains several times a year in the summer months and the mud roofs would be washed away. In Copiapó, where it rains only once in a decade, and in Tacna where it never rains, the roofs are of mud, but in Tarata and here, tiles were in evidence. Ilabaya is a larger place than Tarata, but is a dirtier, and more poverty-stricken place. It is also a terribly hot place, and swarmed with flies and vermin; mangy curs abounded and the odor of the streets abounding with house slops and garbage was disgusting. There were numerous street stands in front of which Indian women sat offering for sale melons, oranges, and pears, but not once during the part of the afternoon that I was there, did I see any purchaser.
