282 THE INCOMING WA VE. CHAP. xiv. 



athwart the pool, its bright colours had a most beauti- 

 ful appearance. The spot on the first dorsal is rather 

 of a dark-purplish colour than black, and very con-

 aware of this species ever before having been detected 

 on this part of the coast." 



Knowing from observation that many marine 

 objects are cast on shore at the rising of each tide, 

 especially when the weather is stormy, Edward walked 

 along the margin of the incoming wave, ready to pick 

 up anything that might be driven ashore. Sometimes 

 he would observe some object in the water a fish or 

 a shrimp of some unusual kind which he desired to 

 capture. He followed it into the sea with a piece of 

 gauze tied on a small hoop ; and fished for it until he 

 had caught it. He discovered many new objects in 

 this way. 



It is almost incredible what may be got along the 

 sea-margin, by carefully searching the incoming wave. 

 This, however, required unwearied assiduity. Edward 

 discovered many of his rarest insects amongst those 

 driven ashore by the wind. It was thus that he 

 obtained most of his rare Crustaceans. He himself 

 had no doubt, that, had his health been prolonged, he 

 would have discovered many more. 



Besides these methods for collecting marine objects, 

 he found that tangle roots were a special hiding-place 

 for many species that were beyond the power of 

 the dredge, and that never entered the traps set by
