 cited for this report, and been furnished with a copy of the 

 analysis by Dr. Chilton, of ihe ore, whieh presents the following 

 very favorable results.

"The proportion of pure iron in the sample is 68.80 per cent.' 



Numerous veins of iron ore have been discovered in the town 

 of Chesterfield, but no one has been extensively worked. These 

 veins ; the Mihill's vein, in Keene ; the several Johnson's beds 

 in Jay ; a new vein just discovered on the premises of Mr. 

 Clark, in St. Armand, and the various other vei^s in different sec- 

 tions of the county, specimens of whlcli have been transmitted to 

 the rooms at Albany, will, I have no doubt, be found when suffi- 

 ciently explored, of great extent, and an excellent quality of ore. 

 I examined in North Elba several large deposits, evidently of a 

 high character of ore. They were singularly overlooked, when 

 the original veins, worked by ihe Elba company, were abandon- 

 ed, and it was judged necessary to transport the raw material 

 from the Arnold bed in Clinton county. It is unnecessary to 

 pursue this topic. The deposits of iron pervade almost every 

 section of the county, and to such a degree, as often to embarrass 

 the operations of the engineer, in the use of the ordinary com- 

 pass. The past history and progress of these mines sustain the 

 conviction, that deposits remain undeveloped of equal magnitude' 

 and high properties, as those already revealed, which will be 

 explored when the demands of business require their develop- 

 ment. 



^ Graphite or Hack lead prevails extensively in various sections 

 of the county, but Ticonderoga and the eastern part of Schroon 

 seemsto hd its peculiar distiict. I obtained very pure and ehoico
