To find out whether bees (蜜蜂) can see colours, the following experiment is made. A round table is put in
a garden, and on the table is a piece of blue cardboard (硬纸版) with a drop of syrup (糖浆) on it. After a short
time, bees come to the syrup. The bees then fly to their hive (蜂房) and give the syrup to other bees in the
hive. Then they return to the feeding-place which they have found. After a while, the blue cardboard with the
syrup on it is taken away. Instead of this card, a blue card is now put on the left side of the first feeding-place

To find out whether bees can see colours, the following experiment is made. A table is put in a garden, and on the table is a blue card with some sugar on it. As soon as one bee finds the sugar, many more come to it one after another in a short time. It seems that one bee is able to tell the news of food to the other bees in their “ home”. After a moment, the blue card with sugar on it is taken away. Instead of this card, another blue card is now put on the left side of the first feeding place and a red card to its right. Nothing can be seen on the two cards. Very soon bees arrive again, and fly towards the blue card. No bees go to the red card.
