REPORT OF THE DIRECTOR 1923 25 
In the judgment of Mr Nevin there seems to be considerable 
available molding sand of good quality still remaining although the 
deposits in this field have been worked for many years; in fact 
since the early days of the iron industry in this country. The region 
still to be developed seems to lie principally in the upper Hudson 
valley in the vicinity of Corinth and Glens Falls, and it appears 
now that future development will probably be in a general northerly 
direction. 
Iron ore. With the recent issue of the report by Mr R. J. Colony 
on the Magnetic Iron Deposits of Southeastern New York, the 
description of the main iron ore areas which at present have the 
most important iron ore deposits has been completed. The Clinton 
iron ore beds of central and western New York, and the magnetic 
iron ore deposits of the Adirondacks have been described in bulletins 
already issued. The rounding out of this subject will enable this 
office to give fairly exhaustive information to those making inquiry 
regarding the main iron-producing areas in the State.
