Notes on the Dispersion of Drift Copper. 49 



sociated formations about the Bay, but does not note native 

 copper, which seems not yet to have been discovered. If it 

 should be found to exist there, this would furnish a second 

 center of dispersion, but as it is nearly north of the Lake Su- 

 perior region, this would not greatly facilitate the explana- 

 tion of the extensive east-west dispersion. 



Fuller notes, which it is proposed to collect at an early 

 date, will doubtless throw fuller, and, it is to be hoped, im- 

 portant light on the question of the dispersion of drift cop- 

 per, the agency or agencies by which it was effected, and 

 their method of action, and this solution may in turn have 

 some bearing upon other interesting geological problems. 



Since the above notes were presented in 1881, the follow- 

 ing additional facts have been secured through the kindness 

 of the parties to whom they are accredited. In Ohio, Mr. M. 

 C. Read states that " there is an important belt of drift run- 

 ning through Licking, Knox and Richland counties, in 

 which many fragments of copper have been found." Mr. C. 

 R. Barnes reports from Indiana, a specimen weighing 3,125.8 

 grams, somewhat flattened, from Moot's Creek, White 

 county. Another piece " four inches long by two and one- 

 half broad, and three-fourths of an inch thick, worn smooth,'' 

 was found " in glacial gravel," in Vermillion county, near 

 Eugene (J. T. Scovell). From the same state, Mr. Joseph 

 Moore gives information of four specimens. One was found 

 near Richmond, Wayne county, weighing 17 oz. Another of 

 two pounds weight was found three miles from Elkhart, 

 Elkhart county. A third piece (mostly carbonate), has been 

 found in Henry county, and a fourth near Brookville, Frank- 

 lin county. Besides these finds, Mr. Moore also states on 

 the authority of Mr. Farrar, that copper is frequently found 

 about Peru, Miami county, in isolated lumps, also that a 

 piece weighing 30 pounds was found " in shelly limestone, 

 where they were excavating for a road." From Michigan, 

 Prof. I. W. McKeever, gives information of a piece of cop- 

 per from Jackson county, which the finde?- (Dr. Baker, of 

 Adrian) believed to be of meteoric origin. It is claimed 

 that it was seen while falling, and taken the next day from 

 the opening found in the earth where the meteor was seen
