"October 10. Called them out at 6.5 A.M. Out of six, five were marked. Shortly afterwards I did the same again, when out of eleven, seven were marked ones. 5.30 P.M. called them out again. Out of seven, five were marked. "October 11. 6.30 A.M. called them out again. Out of nine, seven were marked. 5 P.M. called them out again. Out of seven, five were marked. After this they took hardly any notice of the scents. "Thus in these nine experiments, out of the ninety-seven bees which came out first, no less than seventy-one were marked ones." Many interesting questions connected with the workers remain for future investigation: such, for instance, as whether the same bee returns to the same part of the hive after each foraging expedition; whether the same bees go out in search of stores day after day, or sometimes take holidays or rest from out-door fatigues, by applying themselves to some of the internal labours of the hive; whether those who become more or less exhausted from long-continued flights die, for the most part, on their journeys, or come back home to end their lives. One point not known to general readers is, that a bee on each separate going out for stores confines herself to one particular kind of flower for that expedition. That is to say, a worker who begins on violets, will not visit any other flowers than violets before returning to the hive. If lime-blossoms are chosen, they will be adhered to. If a bee searching white-clover heads be watched, she will be seen to go only to similar sources of supply. This fact may be verified by any one who will take the trouble to notice in field or garden the customs of the hive-bee. It does not seem to be the habit of wild bees thus to confine themselves to particular flowers for each journey they make. The importance of this circumstance in the case of our domesticated species, and its influence on the vegetable world, will be noted in a later chapter, when we discuss the relation of bees to flowers.
