"The kind of water is believed to have great influence over the process; soft water is preferred. The Chinese direction is, 'Take it from a running stream; that from mill-springs is the best, river-water is the next, and well-water is the worst;' that is to say, take water well mixed with air. Hence avoid hard water, but prefer tap-water or running water to well-water. It is the practice of a good housewife in the country to send to a brook for water to make tea, whilst she will use the well water for drinking." The mode of making tea in China is to put the tea into a cup, to pour hot water upon it, and then to drink the infusion off the leaves. While wandering over the tea-districts of China, Mr. Fortune only once met with sugar and a tea-spoon. "The merchant invited us to drink tea," writes the Rev. Dr. Lansdell, who recently visited the Mongolian frontier at Maimatchin, "and told us that the Chinese use this beverage without sugar or milk three times a day; namely, at rising, at noon, and at seven in the evening. They have substantial meals at nine in the morning and four in the afternoon." Dr. King Chambers considers tea most refreshing to the dyspeptic if made in the Russian fashion, with a slice of lemon on which a little sugar-candy has been sprinkled, instead of milk or cream. One small cup of an evening is enough. He also gives the following receipt for making invalids' tea:-- "Pour into a small china or earthenware teapot a cup of quite boiling water, empty it out, and while it is still hot and steaming put in the tea and enough boiling water to wet it thoroughly, and set it close to the fire to steam three or four minutes. Then pour in the quantity of water required, boiling from the kettle, and it is ready for use." Miss Nightingale offers a word of advice to nurses upon the amount of tea which should be given. "A great deal too much against tea is," she remarks, "said by wise people, and a great deal too much of it is given to the sick by foolish people. When you see the natural and almost universal craving in English sick for their tea, you cannot but feel that Nature knows what she is about. But a little tea or coffee restores them quite as much as a great deal; and a great deal of tea, and especially of coffee, impairs the little power of digestion they have; yet a nurse, because she sees how one or two cups of tea or coffee restore her patient, thinks three or four cups will do twice as much. This is not the case at all: it is, however, certain that there is nothing yet discovered which is a substitute to the English patient for his cup of tea." CHAPTER V. TEA AND PHYSICAL ENDURANCE.
