 large to permit the Wasps to cross each other. In this, as in the 

 former terrace, all the mouths of the cell are downward and their 

 bases upward, so that the bases of the second terrace form a floor 

 on which the Wasps can walk while feeding the young contained 

 in the first. A third, fourth, and fifth terrace are added in this 

 manner, all alike, the cells being so small that the mother Wasp 

 can not even put her head into them.

It will be seen, therefore, that, as insects never grow after they 

 have assumed the perfect form, the Wasps which have been bred 

 in these cells must be very much smaller than their parent. They 

 are, in fact, the worker wasps, or neuters, as they are sometimes 

 called, whose entire life is devoted to labor, and who, in fact, are 

 undeveloped females.
