 dling depth; the females go down rather 

 lower. Some of these strenuous workers 

 have already, without the aid of a helper, 

 completed or very nearly completed the well 

 required for the laying. On the loth of De- 

 cember, I unearth one of them at a depth of 

 almost four feet. These early diggers are 

 not what I want. Wishing to observe the 

 work when in full swing, I choose subjects 

 buried not too low down In the fields. 



In the centre of the column of earth In 

 each apparatus, I make a shallow hole, 

 which marks the beginning of the burrow. 

 I drop the prisoner down It; and this Is 

 enough to accustom her to the place. A re- 

 corded number of Sheep-droppings are dis- 

 tributed around the opening. Henceforth 

 things proceed of themselves : I have merely 

 to renew the provisions when the need arises. 



The cold season Is spent In the balmy at- 

 mosphere of a green-house; and nothing re- 

 markable happens. A small mound is 

 formed, hardly big enough to fill the hollow 

 of my hand. The hour has not yet come for 

 serious operations.
