Thus prepared the guest will silently approach the sanctuary, and, if a samurai, will leave his sword on the rack beneath the eaves, the tea-room being preeminently the house of peace. Then he will bend low and creep into the room through a small door not more than three feet in height. This proceeding was incumbent on all guests,--high and low alike,--and was intended to inculcate humility. The order of precedence having been mutually agreed upon while resting in the machiai, the guests one by one will enter noiselessly and take their seats, first making obeisance to the picture or flower arrangement on the tokonoma. The host will not enter the room until all the guests have seated themselves and quiet reigns with nothing to break the silence save the note of the boiling water in the iron kettle. The kettle sings well, for pieces of iron are so arranged in the bottom as to produce a peculiar melody in which one may hear the echoes of a cataract muffled by clouds, of a distant sea breaking among the rocks, a rainstorm sweeping through a bamboo forest, or of the soughing of pines on some faraway hill. Even in the daytime the light in the room is subdued, for the low eaves of the slanting roof admit but few of the sun's rays. Everything is sober in tint from the ceiling to the floor; the guests themselves have carefully chosen garments of unobtrusive colors. The mellowness of age is over all, everything suggestive of recent acquirement being tabooed save only the one note of contrast furnished by the bamboo dipper and the linen napkin, both immaculately white and new. However faded the tea-room and the tea-equipage may seem, everything is absolutely clean. Not a particle of dust will be found in the darkest corner, for if any exists the host is not a tea-master. One of the first requisites of a tea-master is the knowledge of how to sweep, clean, and wash, for there is an art in cleaning and dusting. A piece of antique metal work must not be attacked with the unscrupulous zeal of the Dutch housewife. Dripping water from a flower vase need not be wiped away, for it may be suggestive of dew and coolness.
