OTHER PLACES TO BE VISITED.

ing heavy gales of wind has the effect of loosening, and 

 detaching from their place of growth, many species, and 

 more especially those growing in deep water, that are 

 advanced to maturity, which are soon afterwards washed 

 ashore, and will generally repay the algologist for his 

 trouble in searching for them. He ought, indeed, never 

 to miss so favourable an opportunity of adding to his 

 collection. Moreover, he will frequently meet with some 

 of the rarer species which he could not otherwise obtain, 

 except by dredging, a rather troublesome operation, and 

 one which must always be regarded as attended with 

 very doubtful success. 



Although all parts of the strand should be diligently 

 examined, yet the collector should direct his attention 

 especially to three different points, viz., high-water mark, 

 low-water mark, and half-tide level, for in these places 

 he will find the largest masses of sea- weeds accumulated.* 



Many species are found which flourish and vegetate 

 more luxuriantly in localities where small rills of fresh 

 water run into the sea. 



* To persons collecting at Plymouth, it may be desirable 

 for them to know that they will find the largest quantity of 

 rejectamenta thrown up at the following localities, viz., 

 under the Hoe, on the mud-bank of Cremell Passage, at 

 Redding Point, opposite the ballast-pond at Tor Point, and 

 on the shore leading from Bovisand down as far as the 

 Rennie rocks.
