THE STRENUOUS MOLE 231 
I don’t believe it! My Ockley mole has proved 
to me that insect parasites cannot be got rid of in 
that way. The hare’s twitching muscle is not more 
powerful than that of the generality of animals. I 
have seen him make the water fly like a mist out 
of his fur, but the dog can do it nearly as well. 
In the mole the movement is more sustained and, 
I imagine, more rapid, yet the fleas must be able 
to keep their hold on him since we always find him 
much infested by them.
