246 THE UNIVERSE. 



When, as a result of innumerable journeys, the heap has 

 grown large enough, the female lays its eggs in it. Know-

 feet in diameter. The Tartars frequently appropriate the 

 fruits of its labor in order to feed their horses. Some day 

 perhaps man will in the same way make use of the nests of 

 the Talegallas, which are even more laborious gleaners.

WORK AND THE FAMILY. 



THE whole tribe of wrens and titmice make us forget 

 their tiny size in the skilful finish of their work, and the 

 delightful love which reigns in every family ; their house-

Among these charming guests of our thickets we may

 mouse, the globular abode of which does not exceed the size
