The bees did not see the Institute, but in nearly every case 
started in the right direction before flying up over the tops of 
the houses which were between them and the hive. Memory 
pictures do not seem to aid them on their homeward journey, but 
some unknown force, which from the following experiments seems 
to guide them not to the hive but to a point in space which may or 
may not be the one in which the hive stands or stood. 
Of a number of bees carried in a box a long distance from the hive 
and liberated, not all returned to the hive, but some, after circling in 
the air for some seconds, returned to the box, which had been set on 
a rock before being opened. 
These bees were thrown into the air again, and the box removed. 
This time the bees came to the spot where the box had been. 
The bees were again liberated while holding the box in the hand 
above the ground, then stepping back some distance the bees were 
observed to come to the space where the box had been and to circle 
about it some time.
