MR. AND MRS. TUMBLE-BUG 
know by instinct why those 
powerful front feet were given 
to him, and he is quickly 
working his way to the 
surface, and in a day or 
so is seen in the barn- 
yard rolling his ball as 
skilfully as his mother 
had done before him. 
Such is the method 
always employed by the 
tumble -bug as I have 
seen him. And yet I 
have read in many nat- 
ural histories, and have 
heard careful observers 
claim, that the hole is 
dug first and the ball 
rolled in. Perhaps they 
vary their plan, but I 
doubt it. Here is a mat- 
ter for some of our boys and girls to look into.
