BEES AND WASPS — SENSE OF DIRECTION. 147 
six journeys, the way between the postern entrance and 
the food. 
But the following observation on a wasp is in this con- 
nection the most conclusive. 
A marked wasp visited honey exposed in the room 
before mentioned. 4 The next morning she came — 
A.t 7.25, and fed till 7.28, when she began flying about the 
room and even into the next ; so I thought it well to 
put her out of the window, when she flew straight 
away to her nest. My room, as already mentioned, 
had windows on two sides ; and the nest was in the 
direction of a closed window, so that the wasp had to 
go out of her way in going out through the open one. 
At 7.45 she came back. I had moved the glass containing the 
honey about two yards ; and though it stood conspi- 
cuously, the wasp seemed to have much difficulty 
in finding it. Again she flew to the window in the 
direction of her nest, and I had to put her out, which 
I did at 8.2. 
At 8.15 she returned to the honey almost straight. 8.21, she 
flew again to the closed window, and apparently could 
not And her way; so at 8.35 I put her out again. It 
seems obvious from this that wasps have a sense of 
direction, and do not find their way merely by sight. 
At 8.50 back to honey, and 8.54 again to wrong window ; but 
finding it closed, she took two or three turns round 
the room, and then flew out through the open 
window. 
At 9.24 back to the honey; and 9.27 away, first, however, 
paying a visit to the wrong window, but without 
alighting. 
At 9.36 back to the honey, and 9.39 away, but, as before, going 
first to wrong window.

She was away therefore 9 minutes, 
away, this time straight. „ 11 „
