the promised dinner, but at half-past-one climbed up a steep hill, in the rear of the town-house, to the home of the presidente’s father, where a very elaborate meal had been prepared, with wine and luxuries.  All payment was refused, and, after we had rested and refreshed ourselves, we left at half-past-two.  The road was long; it followed the side of a great gorge, into which it descended abruptly; in this gorge we saw magnificent vegetation.  The trees were heavily hung with long vines and ferns; parasitic fig trees, hugging victims whose life sap they were stealing, were abundant.  The country was of limestone.  On the whole, the road was good, but, here and there, were patches where we traveled over sharp and jagged out-croppings of rock, and near Huehuetla we were forced to make some stiff climbs up the cliff sides.  Flocks of parrots were numerous, especially toward evening.  The stream was a handsome one, with clear, deep water; we crossed and recrossed many times.  The foot-paths rarely crossed, being cut sometimes, as a narrow trail, in the rock of the cliff.  Noticeable were numerous silvery lines of water falling over the cliff, several of which must have been hundreds of feet in height; these little threads of water were impregnated with lime, and deposited material in a sheet upon the bank over which they flowed, so that trails of brown tufa marked their location; the lower ends of these deposits expanded into fan-like masses of tufa, over which the water trickled, dripped or fell.  Where there was not sufficient water to produce a stream and fall, but enough to keep the tufa moist, the growth of ferns, and other delicate vegetation, was brilliant and striking.  We passed a number of coffee and sugar ranches on the road.  It was dark long before we reached Huehuetla, and had it not been for the moonlight struggling through the clouds, we should have had difficulty in traveling the last portion of the road.  At 7:35 we arrived, and went at once to the large and handsome house of Don Pablo himself, where we were expected, and where an elaborate supper was being made ready.  The largest room in the house was put at our disposal and good beds and cots, beautifully clean and carefully made, were ready.  Formerly, Don Pablo was the presidente of the town.  His successor was at the house to meet us, within five minutes after our arrival, and took supper with us.  It is needless to say that in this town we met with no delays in our work.  To our surprise, we found a fellow countryman, a civil engineer named Culin, from Philadelphia, who has done and is doing much work for the pueblos of this region.
