The other sections are not so detailed but show about the same 

 relations. Section No. 2 was run 268 feet south of No. 1 or middle 

 section and gave a width of 610 feet of ore without apparently 

 encountering the walls. Section No. 3 crossed the ore body 21a 

 feet south of No. 2, and No. 4 was run 231 feet north of No. 1; 

 their length is not stated. On the basis of this work Professor 

 Emmons estimated the ore body to contain 6,830,000 tons at a 

 depth of 2 feet below the adjoining surface. The results obtained 

 by diamond drilling during the years 1906 and 1907 have demon- 

 strated that the ore continues westward practically to the lake 

 side considerably farther than Emmons was able to trace it, while 

 they have also proved its continuity to a depth of 300 or 400 feet, 

 as far as the drills have penetrated. Recent magnetic surveys 

 show the existence of lines of attraction which cross the lake to 

 the western shore where they merge with the smaller ore body
