The grounds were a succession of orchards, fields, and vineyards. Scores of Indians lived and worked on the place, cultivating the ground, building stone fences, and taking care of the stock. At night they met and played very well on reed flutes of various sizes, each musician taking a separate part, so that the combined effort was somewhat like that produced by a well-organized band. Their favorite piece was “Red-Wing”--apparently learned from a phonograph record. The evening parties were always enjoyable affairs. They began with a sumptuous dinner--including several kinds of wine; then a series of eight or ten well-chosen courses, followed by liqueurs and smoking. The women did not smoke. After that there were charades, story-telling, music, singing, dancing, and perhaps a walk _en masse_ in the moonlit grounds, through arbors of honeysuckle and other flowering vines and over paths bordered with hedges of roses. There were always more refreshments just before the party broke up at midnight. All the Bolivians we met at Peras Pampa were charming, and we heartily regretted that our time for combined work and play was not unlimited. The majority of the people who formed the gay evening crowd lived in separate cottages on the estate--the guests of the owner. Each day they repaired faithfully to the river for a dip, although the water was usually very muddy, and there was about an even chance whether one would emerge without yesterday’s coat of grime or with an additional one. December is chosen for this purpose because it is the warmest and most pleasant month of the year. The time allotted us for work in Bolivia had nearly expired. We had thoroughly enjoyed our lengthy sojourn in the republic, and look forward to revisiting it in the future. Our schedule called for rather extensive work in the Argentine, so, after a great deal of difficulty, we succeeded in collecting a caravan of riding and pack mules for the ride of over three hundred miles to La Quiaca, on the Argentine frontier. Ordinarily the trip from Sucre to La Quiaca should not be undertaken on mule-back. One should go to Potosi in one day’s time, utilizing the semiweekly motor-car service. A railroad connects the latter place with a small station a few miles this side of Tupiza, and from this point one may reach La Quiaca in two days by carriage. During the rainy season, however, both automobile and carriage service are suspended; and the difficulty of twice securing mules on which to cover the two stretches of road between railway terminals and the delays and other inconveniences are so great that we decided to travel the entire distance with a pack-train. This also gave us an opportunity to see the country.
