OnMoles. 139 



6. At what season of the year does the mole bring 

 forth her young ? Or has she not at least, two litters in 

 the year ? What is the number of young produced by 

 a single pair, in the year ? 



7. May we not, by preserving moles from unneces- 

 sary destruction, turn their beautiful fur to useful pur- 

 poses in the United States ? 



I am, dear Sir, 



Very respectfully, yours, &c.
