THE “ COMMITTEE ” TARGET. 
Experiment carried on 4th March, 1862, against a Target proposed by the 
Special Committee on Iron, constructed by Messrs Eairbairn and Co. of 
Manchester. 
The target (20x10 ft.) was composed of two plates 20' x 3' 4" x 4J", and 
two plates of 9' x 3'4" x 4i", the upper and lower of which were secured by 
fifteen 2" bolts, and the two centre by eight 2" bolts each. 
The armour-plates were fastened to 1" plates, which latter formed the skin 
of the ship, which was supported by ribs 18" deep, and 18" apart, made of 
J" plates secured by angle irons 4" x 4" x f"; the back of the ribs were 
secured by four strips of plate 12" x 4". 
Strips 10' x 9" x f" were behind the skin along each line of bolts. 
The armour-plates were rolled by Messrs John Brown and Co., Sheffield.
