The additions consisted of 13-2 Ibs. of siliceous sand and 12-2 
Ibs. of limestone. 
The charcoal used in the last experiment, per 100 lbs. of ore, was 
25-75 lbs; and 4-7 lbs. (per 100 lbs. of ore) remained in the furnace. 
The net amount used, 21-0 lbs. was therefore intended for this run, 
but only 20-5 lbs. wasactually charged. The fine material was agglom- 
erated with water and 7 lbs. of water glass; a larger amount being 
needed for this charge. 
The smelting operation was carried out satisfactorily and the 
slag and metal were tapped out three times during the run which 
lasted three hours; the slag was quite fluid.
