The analyses were made from crude ore, but the quantity o 

 sulfur shown is rather low for the run of mine, specially in the 

 second sample which also contains very little phosphorus. It is of 

 interest in this connection to quote Professor Silliman's analyses 

 of the pig iron made from the Clifton ores in the old Clarksboro 

 furnace. The ore was fluxed with an impure limestone containing 

 a considerable proportion of silica.

In the same vicinity occur two other deposits that were found 

 by the early prospectors and were known as the Tooley Lake and 

 Sheridan veins. They outcrop in a swampy tract, 7 and 2\ miles 

 distant respectively from the Clifton mines. The localities were 

 not visited by the writer. In character the ores are similar to 

 those just described, as shown by the following analyses, no. 1 

 being from a sample of the Tooley Lake vein and no. 2 of the 

 Sheridan vein.
