The ore of *Jowli* (No.15) is the *ochrey* variety of red oxide, it is almost a pure oxide, and affords a good pigment; it soils the fingers deeply, and its stain on cloth is difficult to wash out; it melts more easily than the former, and on actual experiment 185 sers, smelted by 165 of charcoal, produced 77 sers of crude iron *en masset*, in something less than ten hours, which is nearly 42 per cent; it is associated with a compact variety, (No.16 and 17) which appears to contain *specular ore*, from the blood red colour reflected from its small crystals when fresh from the mine; it lies near the border of a range of trap hills, and is clearly a deposit, or a vein, in the fissure of a rock resembling *hornstone* (No.18) which has probably been thus changed by contact with the trap.
