302 Col. Beaujoy's Astronomical Observations, [April, 



when it was put on; but I never saw a ship^s bottom more thickly 

 studded with barnacles, nor any that were more difficult to scrape 

 off. They were all rather small. It was only on the lower part 

 of the bows, and about two inches above, and four inches below 

 the iron bars that the copper was not covered with barnacles; 

 excepting the upper part of it which had been little under water. 

 " Several vessels are expected to return from the East and 

 West Indies in the ensuing montli, having had wrought iron 

 applied in the same manner that the cast iron was in the Tickler.
