AND THE CHILDREN.

Alia! Here it is behind the pan. She likes to hide 
herself. 
Let us take a nest that seems to be aoancloned, for 
there are plenty of them here. 
Clay seems to be the make-up of the walls of the 
house. But it is strange how the little workers could 
have gotten together so much material. Here however 
is a good lesson—it was done little by little. By 
small pieces the dirt was brought and stuck together, not 
all in one lump. So it is in life. No great thing has 
been done with unusual exertion but it has been done 
little by little. There is a similarity between the Mud- 
wasp and Paper-wasp in that the eggs are laid in separate 
cells or apartments, not like the Humble-bee which lays 
all its eggs together. 
But very unlike the Paper-wasp, its humble, little 
home is a “clay house.” In the little chambers of the 
house are the eggs, one in each chamber. Carefully 
break away the outside wall. Notice the brown cocoon. 
Tear it open to see what it contains.—At one end, the 
grub of the young wasp but that does not fill up the 
whole chamber. At the other end are three or four little 
spiders which I think, are intended for food for the little 
wasp when it is old enough to eat.
