Report of the State Geologist. 



The open cut gives no indication of the actual size of the ore-body except 

 so far as the failure to reach the walls implies that it is large. A line of 

 attraction has been traced down to the lake, however, across it and on the 

 other side where the name Sanford appears again. A second line of attraction 

 has also been noted crossing the lake further south. 



In Professor Emmons's day, four sections were uncovered on the east side 

 of the lake, across this vein by trenching. The longest were 564 feet and 610 

 feet respectively, and they exposed ore with occasional streaks of rock for the 

 entire distance. These trenches have long since become filled in, but there is 

 no doubt that the supply of ore is enormous. By the -heavy lines running 

 into the Sanford ore-bed I have endeavored to locate these trenches as 

 accurately as possible from the descriptions of Professor Emmons. Were 

 mining again begun, the Sanford ore would naturally be the one first attacked 

 and the indications are favorable to many years of open cut work above the 

 level of the lake. 



The composition of the ore is shown by the following analyses of which 

 the first four are given by Mr. Rossi in the Iron Age, February 6, 1896 :

Experimental attempts to concentrate the ore with magnetic machines 

 were made some years ago in the hope that the richly titaniferous portions 

 could be separated from the non-titaniferous, on the assumption that the 

 latter variety was more highly magnetic than the former. All such ex peri-
