92 FISHES I HAVE KNOWN 



thickens hourly, and finally, if the ship's course be 

 through the centre of the sea, which it seldom is, 

 it becomes dense enough to impede navigation, and 

 the water looks like a meadow thick with grass. 

 We only touched the edge of it, but contrived with 

 a bucket to scoop up a fair quantity for examination. 



The weed is the home of all kinds of small 

 creatures crabs, strange molluscs, delightful little

 their paddles send out iridescent hues on the waten 

 and thus catch the eye.

 mounted on a long rod, but I had to improvise 

 one out of some stout muslin and an iron cask
