Extract from the report of Prof W. R. Johnson^ of experiments 

 made on the Iron manufactured at the village of McLifyre^ Essex 

 county^ Kew- York. 



After presenting a detail of experiments, by which he tests and 

 confirms '-'• the freedom of this iron from the defects known either as 

 hot shortness cr cold shortness, and its softness and malleability, by 

 the cutting and hammering incident to these experiments," Prof. 

 JohDSon continues, " the next step was to determine the absolute 

 force of cohesion, together with the extensibility, when subjected 

 to longitudinal strain, and the interior structure of the metal 

 under various circumstances, including that of welding in the or- 

 dinary way." 



For this purpose, five bars were drawn out and prepared from 

 the specimens, numbered I, II, III, IV and V, each about nine or 

 ten inches long one inch wide, and two inches thick. 



No. I after being reduced to a nearly uniform size, throughout 

 its length, w^as annealed at a red heat and allowed to cool slowly 

 in the air. 



No. II w^as hammer hardened, or beaten with moderate force 

 throughout its length, until it had been for several minutes black, 

 the hammer being occasionally moistened during the process. 



No. Ill was forged out and hammered till it was only visibly red 

 in day light, being left at about the temperature at which the
