found the true. Not one flew straight into the nest. One, dis¬ 
tinguished by carrying a long worm, entered the false hole four 
times and then rose, and circling more widely, flew into the 
true. 
From 9:20-9:25 of 152 which entered the false 89 afterward 
found the true hole. Not one flew straight into the nest, al¬ 
though the wasps were coming out in a steady stream which 
might have indicated the entrance. 
We now moved the false hole two feet to the south of the 
nest, leaving it just east of a tree while the true hole was north 
east 
From 9:28-9:33 107 entered the true hole, 103 the false. 
None flew straight into the true hut some did not go near the 
false. Some settled on the ground trying to find the hole. We 
received no stings although excited swarms w ere fl} ing a out 
us. The wasps found their nest under a paper of a color new to 
them much more readily than they found it when the paper 
was taken away entirely and the ground left exposed. 
In the afternoon of the same day we moved the yellow paper 
so that the hole in it was six inches south of the entrance, and 
put a red paper over the nest. 
From 4:18-4:23 10 entered false hole, 37 the true hole.

The wasps seemed to remember these changes and to look f 
the entrance itself. We thought that many flew a itte way 
toward the false hole and then turned back to the true, 
though so many entered the false hole not one leturne o l 
uor circled about it as they had so commonly done. e 
changed the position of the yellow paper severa times wi 
few hours and once while we were absent it flew over the ho e 
and remained there for some time. # 
On the morning of August 23, the red paper having been over 
the nest for two days and a half, we substituted the green paper ^ 
and moved the red twelve inches to the^south.
