MATTERS, INCLUDING PETS AND INSECTS 



fat caterpillars to be pushed in head first, is hermet- 

 ically sealed up and another room begun and joined 

 on to it. This is repeated till ten or twelve rooms 

 are built, measuring eight inches long or so. The 

 hornet brings a round lump of mud and joins it on 

 to the building by making it damp and flattening it 

 into shape. Presently my hornet returned no more 

 and I left the mud alone for some time ; curiosity 

 got the better of me, however, for one day I pulled 

 it down, partly because I did not want a dozen black 

 hornets flying about, and partly to see what was 

 happening inside. I found a perfect white hornet 

 in the first and hornets in different stages of de- 

 velopment in the others. My boys say these insects 

 can sting very badly.
