Reference has been made to buying hot water. In a sampan managed by a woman and her daughter, who took us ashore, the middle section of the boat was furnished in the manner of a tiny sitting-room, and on the sideboard sat the complete embodiment of our fireless cookers, keeping boiled water hot for making tea. This device and the custom are here centuries old and throughout these countries boiled water, as tea, is the universal drink, adopted no doubt as a preventive measure against typhoid fever and allied diseases. Few vegetables are eaten raw and nearly all foods are taken hot or recently cooked if not in some way pickled or salted. Houseboat meat shops move among the many junks on the canals. These were provided with a compartment communicating freely with the canal water where the fish were kept alive until sold. At the street markets too, fish are kept alive in large tubs of water systematically aerated by the water falling from an elevated receptacle in a thin stream. A live fish may even be sliced before the eyes of a purchaser and the unsold portion returned to the water. Poultry is largely retailed alive although we saw much of it dressed and cooked to a uniform rich brown, apparently roasted, hanging exposed in the markets of the very narrow streets in Canton, shaded from the hot sun under awnings admitting light overhead through translucent oyster-shell latticework. Perhaps these fowl had been cooked in hot oil and before serving would be similarly heated. At any rate it is perfectly clear that among these people many very fundamental sanitary practices are rigidly observed. One fact which we do not fully understand is that, wherever we went, house flies were very few. We never spent a summer with so little annoyance from them as this one in China, Korea and Japan. It may be that our experience was exceptional but, if so, it could not be ascribed to the season of our visit for we have found flies so numerous in southern Florida early in April as to make the use of the fly brush at the table very necessary. If the scrupulous husbanding of waste refuse so universally practiced in these countries reduces the fly nuisance and this menace to health to the extent which our experience suggests, here is one great gain. We breed flies in countless millions each year, until they become an intolerable nuisance, and then expend millions of dollars on screens and fly poison which only ineffectually lessen the intensity and danger of the evil.
