 the contents of Vol. 47, but will cite the following interesting fact. 



The vessels employed in the New Foimdland fishery, which ex- 

 port salt, and return salted fish in hxdk, are known to be exempt 

 from destruction by rot. This fact induced Mr. Carey, in 1786, when 

 building in the Gulf of Canso, a schooner, of timber green from the 

 woods, to fill the spaces between the timbers with a mixture <^ 

 salt, fish oil and pounded charcoal, with stops of wood inserted 

 here and there, to keep the composition in place. Thirty years after, 

 this schooner was in perfect preservation, since which her history 

 has been lost ; but it is not impossible that she may be still safe and 

 sound. Mr. Carey received a prize medal from the society.
