that the apex of the fan of diamond distribution probably lies 

 somewhere in the strip of territory bordering James Bay on 

 the east. 



DATA NEEDED TO DEFINITELY LOCATE THE SOURCE OF SUPPLY 



OF DIAMONDS 



Before the home of the diamonds can be located with 

 definiteness, it will be necessary to carry out several lines of 

 investigation. Of first importance is it that the direction of ice 

 movement be studied in as much detail as possible in the terri- 

 tory surrounding Hudson Bay on the southwest, south, and 

 east. It will be important also to search the moraines south of 

 the lakes, and particularly the marginal ones, for diamonds, since 

 the evidence points to them as the principal repository of the 

 emigrated stones. It is especially important to examine the 

 moraines of Ohio, western New York and western Pennsylvania, 

 in order to determine whether the fan of distribution extends 

 farther in that direction. If this is true, the apex of the fan 

 would seem to be located very near to the center of the 

 Labradorean neve. 



It has seemed to the writer that much might be gained by 

 arousing an interest in the problem in the people who reside on 

 or near the moraines, and suggesting to them that children 

 particularly be urged to use their keen eyes in search for the 

 diamonds that have been sown in the drift. To this end a brief 

 statement has been prepared which sets forth what has already 

 been learned regarding the lake diamonds, and explaining how 

 rough diamonds may be distinguished from the ever present 

 quartz pebbles. For identification of stones the persons finding 

 them are referred to mineralogists, who are competent to pass 

 upon gem stones, and who are willing to do so without com- 

 pensation because of their interest in the problem. It is hoped 

 that the editors of local newspapers in the morainal belt, to 

 whom the statement will be mailed, will be willing to cooperate 

 by printing it, and thus aid materially in disseminating the 

 needful information. Wm. H. Hobbs.
