continually shifting its place, and the 

 attrition of the various parts is so great, that even the 

 hardest rocks contained in it are, at length, ground down to 

 powder. But when sand and sediment are swept by a flood 

 over lands bordering a river, such an alluvium may envelop 

 trees or the remains of animals, which, in this manner are 

 often permanently preserved. In the mud and sand pro-

 channels are left high and dry beyond the reach of floods, in 

 which case the organic remains may be preserved for ages
