     A story tells that a senior villager led some other villagers carrying salt day and night to a town in order to

trade rice as food the winter. One night they camped in a wilderness with a starry sky above. The senior

villager, obeying the tradition passed down from forefathers, took out three blocks of salt and threw them into

the campfire, probably to predict the changes of weather in the mountains.

     All eagerly waited for the old man's" weather report":if the salt in the fire produced crackling sound, they

would have good weather in store;if no sound was produced, it then meant the good weather would soon end

and a storm would come at any moment.

     The senior villager looked serious. The salt in the campfire made no sound at all. Convinced by this bad

sign, he urged (催促) the whole team to set out immediately after daybreak. A young man in the group,

however, insisted that they should not start in such a hurry, considering it superstitious to" forecast weather by

using salt.

     It was not until the next afternoon that the young man caught up on the wisdom of the old man when the

weather suddenly changed, with cold winds blowing and a snowstorm raging. In fact, the method used by the

clan head could be well explained by modem science:whether or not salt produces sound in campfire depends

on air humidity (湿度).That is to say, when a storm approaches, due to high humidity, the dampened salt

blocks will not produce any sound in fire.
