Mr. R. T. Baker, on behalf of Mr. P. U. Oakes, exhibited 

 several turpentine piles, which had been driven in the 

 waters of Leycester Creek, Lismore, about five years age; 

 these waters are fresh, but have a tide rise and fall of from 

 two to three feet. These piles have been absolutely 

 destroyed by the ravages of the Teredo navalis during that 

 time.
