This was her last visit for the evening, and she thus 
made no less than 116 visits in the day, during which 
time only three other wasps found the honey, though it 
was lying exposed on a table at an open window. It 
will be seen that she worked with the utmost industry. 
No doubt, however, if a wasp is put to honey in an 
exposed place, other wasps gradually find their way to 
it. In the preceding experiments some few, though 
but few, did so. I then thought I would try a similar 
experiment with concealed honey. Accordingly, on 
September 20, I marked a wasp and put her to some 
honey, which she visited assiduously. The following 
morning I opened my window at 6, and she made her 
first visit at 6.27, the temperature being 61° Fahr. I 
then placed the honey in a box communicating with 
the outside by an india-rubber tube 6 inches long and 
4 inch in diameter. The wasp, however, soon got accus- 
tomed to it, and went in and out without much loss of 
time. The 22nd was finer; and when I opened my 
window at 6 in the morning, she was already waiting 
outside, the temperature being 61°. The 28rd was 
rather colder, and she came first at 6.20, the temperature 
being again 61°. 
I was not at home during these days ; but, as far as
