entrance of Poole harbour and foundered ; tlie crew were 

 saved, but tlie vessel and cargo remain to tliis day at the 

 bottom. Since that period the shoal at the entrance of the 

 harbour has so extended itself in a westerly direction towards 

 Peveril Point in Purbeck, that the navigable channel is thrown 

 a mile nearer that point.^ The cause is obvious : the tidal 

 current deposits the sediment with which it is charged around 

 any object which checks its velocity. Matter also drifted 

 along the bottom is arrested by any obstacle, and accumulates 

 round it, just as the African sand-winds, before described, 

 raise a small hillock over the carcass of every dead camel 

 exposed on the surface of the desert. 



I before alluded to an ancient Dutch vessel, discovered in 

 the deserted channel of the river Eother, in Sussex, of which 

 the oak wood was much blackened, but its texture unchanged. 

 (See above. Vol. I. p. 528.) The interior was filled with fluvia- 

 tile silt, as was also the case in regard to a vessel discovered
