 to procure fish in the rivers which are become 

 deeper, as when you are sailing on the open sea. 

 It often fails the poor missionaries, on fast days

 crust has a tint inclining to red, owing to the 

 oxid of iron which is mingled with it. We 

 brought away some of this earth, which we took 

 from the winter provision of the Indians ; and it
