out intermission the whole day, and was more or less 
regularly visited by the marked bees and wasps. 
My experiments, then, in opposition to the state- 
ments of Huber aud Dujardin, serve to show that wasps 
and bees do not in all cases convey to one another in- 
formation as to food which they may have discovered, 
though I do not doubt that they often do so. Of 
course, when one wasp has discovered and is visiting 
a supply of syrup, others are apt to come too; but I 
believe that in many instances they merely follow one 
another. If they communicated the fact, considerable 
numbers would at once make their appearance ; but I 
have not often found this to be the case. The frequent 
and regular visits which my wasps paid to the honey 
put out for them, prove that’ it was very much to their 
taste; yet: few others made their appearance. 
These and other observations of the same tendency 
seem to show that, even if wasps have the power of in- 
forming one another when they discover a store of good 
food, at any rate they do not habitually do so. 
On the whole, wasps seem to me more clever in 
finding their way than bees. I tried wasps with the 
glass mentioned on p. 278, but they had no difficulty 
in finding their way out. 
My wasps, though courageous, were always on the 
alert, and easily startled. It was, for instance, more 
difficult to paint them than the bees; nevertheless, 
though I tried them with a set of tuning-forks covering
