CORRECTIONS AND ADDITIONS.

Page 142, 16th line from bottom, for Bellaire, read Meigs Creek or Barnesville. 
Page 283, 5th line from bottom, before Barnesville, read Meigs Creek or. 
Page 654, 6th line from top, for 100, read 10. 
Page 714, 16th line from top, for 4s, read 1-12. 
An unfortunate omission occurs in the list of the Early Blast Furnaces of Ohio, on page 450, and 
one or two corrections need to be made. 
The list should begin as follows: 
1808, Hopewell Furnace, Poland, Mahoning Co., Daniel Heaton. 
1806, Montgomery Furnace, Struthers, Mahoning Co., Montgomery and Struthers. 
1807, Rebecca Furnace (Dale), New Lisbon, Columbiana Co., Gideon Hughes, kidney and lime- 
stone ores. 
Hopewell Furnace was sold in 1807 to Montgomery, Clendennin & Co., and it becomes the Yellow 
Creek Furnace, which heads the list on page 450. 
Lhe list should be supplemented by the insertion of the following item: 
1840, 
Furnace, Calcutta, Columbiana Co., Arnold Downey, kidney and block ores.
