72 THE WONDERS OF INSTINCT 



But those who in the other races are unemployed in this 

 case labor valiantly, now in the interest of their own 

 family, now for the sake of another's, without distinction. 

 If a couple is in difficulties, helpers arrive, attracted by 

 the odor of carrion; anxious to serve a lady, they creep 

 under the body, work at it with back and claw, bury it and 

 then go their ways, leaving the householders to their

 When all is in order, the couple go forth, dissolving their

 elsewhere, even if only as a mere auxiliary. 



Twice and no oftener hitherto have I found the father 

 preoccupied by the future of his sons and laboring in 

 order to leave them rich : it happens with certain Dung- 

 beetles and with the Necrophori, who bury dead bodies. 

 Scavengers and undertakers both have exemplary morals. 

 Who would look for virtue in such a quarter? 



What follows — the larval existence and the metamor- 

 phosis — is a secondary detail and, for that matter, fa-

 About the end of May, I exhume a Brown Rat, buried by 

 the grave-diggers a fortnight earlier. Transformed into

 are also stirring amid the infected mass. The period of 

 hatching is over now; and food is plentiful. Having
