Even in the city of La Plata, the second of importance in Argentina, I once had the misfortune to fall into an open drain while passing down one of the principal streets. The night was intensely dark, and yet there was no light left there to warn either pedestrian or vehicle-driver, and _this sewer was seven feet deep_. Simple rusticity and ignorance are the chief characteristics of the country people. They used to follow and stare at me as though I were a visitor from Mars or some other planet. When I spoke to them in their language they were delighted, and respectfully hung on my words with bared heads. When, however, I told them of electric cars and underground railways, they turned away in incredulity, thinking that such marvels as these could not possibly be. Old World towns they seem to be. The houses are built of sun-baked mud bricks, kneaded by mares that splash and trample through the oozy substance for hours to mix it well. The poorer people build ranches of long, slender canes or Indian cornstalks tied together by grass and coated with mud. These are all erected around and about the most imposing edifice in the place--the whitewashed adobe church. All houses are hollow squares. The _patio_, with its well, is inside this enclosure. Each house is lime-washed in various colors, and all are flat-roofed and provided with grated windows, giving them a prison-like appearance. The window-panes are sometimes made of mica. Over the front doors of some of the better houses are pictures of the Virgin. The nurse's house is designated by having over the doorway a signboard, on which is painted a full-blooming rose, out of the petals of which is peeping a little babe. If you wish to enter a house, you do not knock at the door (an act that would be considered great rudeness), but clap your hands, and you are most courteously invited to enter. The good woman at once sets to work to serve you with _máté_, and quickly rolls a cigar, which she hands to you from her mouth, where she has already lighted it by a live ember of charcoal taken from the fire with a spoon. Matches can be bought, but they cost about ten cents a hundred. If you tell the housewife you do not smoke she will stare at you in gaping wonder. Their children use the weed, and I have seen a mother urge her three-year-old boy to whiff at a cigarette.
