In this ochre, which forms large beds on the outcrops of the more fer- 
ruginous feldspathic rocks, one has a superior flux for any heavy burden 
ore, especially fora close titaniferous ore. The ochre must become a fluid 
double silicate, without robbing the ore, and will carry off the titanic acid 
in excess. 
One of the constituent elements of the whole formation is Ochre, in 
beds of various sizes. What the exact geological relationship of these 
ochre beds to the magnetic ore-beds is, I do not know. But the ochre 
outcrops seem to be always in the immediate vicinity of the ore-beds. 
The largest exhibition of ochre which I saw is on the J. Somers Planta- 
tion on Brushy Creek. Here an ochre bed twenty feet thick rises, nearly 
vertical, out of a gully in a hillside covered with small pieces of fine com- 
pact ore. 
Bar-iron Analysis, by A. A. Fesquét, April 4, 1870. 
“The samples of iron bars which you gave me to analyze have the fol- 
lowing composition :

“T would judge from the nature of the samples, and former. analysis, 
that the proportion 0.47 per cent. under head of Carbon, &c., is too con- 
siderable to be formed by Carbon alone, and comprises, very likely, carbon 
and oxygen. Therefore I would judge that part of the impurities is from 
oxide of iron, and the remainder from slag, which I have ascertained ex- 
perimentally. In other words, the impurities are due to a highly basic 
slag, which cannot be expelled or squeezed out by the hammer and the 
rolls.”’

by Jas. Rowland & Co., not cut and piled.
