Gives the opinions held as to the origin of lake iron-ore. Instances 



from Swedish and Finlandic lakes are given showing that the growth 



of the ore is very slow, and, perhaps, almost imperceptible. The 



bottom of the lake Tisken, near the Falun copper-mine in Sweden, has 



been, in a period of 600 years, covered with a layer of loose earthy 



ochre 10 feet thick, which, during this long period, has not attained 



either the consistency or any other property of the ordinary lake-ore 



used for iron-melting. E. E.
