BEES AND WASPS— SENSE OE DIRECTION.

substance such as glass. But to this latter point we shall 
presently have occasion to return. 
Next we must adduce evidence to show that in way- 
finding the 6 sense of direction 5 in bees appears to 
be largely supplemented by observation of particular 
objects. 
Sir John Lubbock observes : 6 1 never found bees to 
return if brought any considerable distance at once. By 
taking them, however, some twenty yards each time they 
came to the honey, I at length trained them to come to 
my room ; 5 that is to say, bees require to learn their way 
little by little before they can return to a store of honey 
which they may have been fortunate enough to find ; their 
general sense of direction is not in itself a sufficient 
guide. This, at least, is the case where, as in the experi- 
ments in question, the bees are carried from the hive to 
the store of honey (here a distance of less than 200 
yards) : possibly if they had found the honey by them- 
selves flying towards it, and so probably taking note of 
objects by the way, one journey might have proved suffi- 
cient to teach them the way. But, whether or not this 
would have been the case, the fact that when carried they 
required also to be taught the way piece by piece, is con- 
clusive proof that their sense of direction alone is not 
sufficient to enable them to traverse a route of 200 yards 
a second time. 
The same result is brought out by other experiment ? 
conducted on a different plan, though not apparently 
with this object. 6 My room is square, with two windows 
on the south-west side, where the hive was placed, and 
one on the south-east. 5 Besides the ordinary entrance 
from outside, the hive had a small postern door opening 
into the room. 
At 6.50 a bee came out through the little postern door. After 
she had fed, she evidently did not know her way home ; 
so I put her hack. 
At 7.10 she came out again. I again fed her and put her 
back. 
At 10.15 she came out a third time; and again I had to put 
her back.
