ELIZABETHTOWN AND PORT HENRY QUADRANGLES 99 



early mining industry was prompted by the call for ore for the 

 small blast furnaces which still remain in states of indifferent 

 preservation. Plate 13 is from a photograph of the old Colburn 

 furnace which was built in 1848, and which still stands about a 

 mile west of Moriah Center. Another one is represented by a pile 

 of collapsed masonry, at Fletcherville, also called '' Seventy five " 

 a mile and a half north of Mineville. At Port Henry there was a 

 furnace at Cedar point, even in Professor Emmons's time, and 

 this is the site of the large plant now in full blast. Twenty years 

 ago there were two other blast furnaces called the Bay State, and 

 situated just west of the steamboat clock. The abundant slag 

 along the. shore at this point came from them, but they have since 

 been torn down. 



The old bloomaries or forges were located where there was a 

 water power sufficient to run the blast and the trip hammer. But 

 for 25 years or so they have been extinct. In their day they con- 

 sumed an appreciable fraction of the output of those mines which 

 were low in phosphorus and sulfur. The ore was hauled many 

 miles to them. By 1890, except perhaps at Standish, in Clinton 

 county they had practically gone to the scrap pile."^

Following the map [pi. 17] the ore deposits will be briefly out- 

 lined in order from south to north. 



No. I. This pit now abandoned was opened by Butler and 

 Gillette and continued under the name of the Essex Mining Co. 

 The work was based upon a band of ore and is represented by an 

 excavation 40 feet long and 8 to 10 feet high, sloping at an angle 

 of about 60° and striking approximately n. 12° w. magnetic. 

 The dump alone reveals a rather lean ore with much hornblende 

 and feldspar intermingled. The walls are reddish granitic gneiss. 

 No analyses of the ore are available nor were any samples taken 

 or notes recorded by B. T. Putnam for the Tenth Census. 



In the hill standing in the angle of the highways and northeast 

 of Bullpout pond there is a belt of attraction running in a north- 

 easterly direction. It has led to the opening of some small pits. 

 Attraction apparently extends for a mile, since on the northea::stern
