London.-Bees have a language, expressed in dances and by scent, which enables them to "say" that there is food to be had in plenty, and on which kind of flower it is to be found, Prof. K. von Frisch of Munich, who has spent 27 years in deciphering this language, told a gathering of scientists at University college.
Frisch brought with him a collection of films to prove his points. Here is his story of what happens when a bee brings home a message of plentiful food:
First, the wanderer disgorges its own supply, feeding the younger bees, which is the first duty to the hive. Then it begins a "round dance," moving slowly around in circles.
The dance conveys the one word, "sugar," and there must have been found enough of it to make it worth while for other bees to seek out its source. Otherwise, or if the extraction of the sugar is difficult, the bee will refuse to dance. It will merely go back and collect more.
It will not invite friends to hard labor.
Bees who have found pollen have what Professor Frisch calls the "tail-wagging" dance. Of this, too, he has a cinema record.

Bees use dances to inform hive mates of food sources: a round dance for abundant sugar like honey, and a tail-wagging dance for pollen. The discovering bee feeds younger bees first and dances only if extraction is easy.
