THE SABELLA. 417 



up to the curious Perforated Kock, I saw a tube pro- 

 jecting, just beneath the surface of the water, about 

 H inch long. I could just get my arm into the 

 crevice, and feel the tube with my fingers ; it resembled 

 both in consistency and appearance half-boiled maca- 

 roni. I thought it was a sponge, and tried to pull it

 which I could still dimly see in the muddy water. 



By feeling carefully 1 got hold of the animal, and

It was a large stout w^orm, beset along each side

 pencils, of a golden colour. There was no proper
