NATIVE IRON (Page 382). 
Prof. Shepard refers to the occurrence of a mass of supposed native iron in the town of 
Scriba, near Oswego. The weight was about eight pounds. It was found to be composed 
of iron 99.68, silicon 0.20, calcium 0.09, aluminum traces. Specific gravity 7.50. Asso¬ 
ciated with the above iron, there is a brittle mineral resembling graphite, a part of which is 
magnetic, while the rest is not acted on by the magnet. It is thought to be ordinary magnetic 
iron ore.*
