In March, 1896, a stone was brought to the office of the 

 Wisconsin state chemist, at Milwaukee, which, on examination, 

 proved to be a white diamond of nearly 6]/ 2 carats weight. It 

 was found by Conrad Schaefer, a German farmer at Saukville, 

 Ozaukee county, Wisconsin. In a letter to the writer, Mr. 

 Schaefer says of this stone (translation): 



This diamond is from a little collection of gems, stones, and fossils, also 

 Indian implements, all collected on my land. My land adjoins the Milwau- 

 kee River, and is a drift range running northeast and southwest. I had the 

 stone about fifteen or sixteen years in my possession. 



This diamond was purchased by Messrs. Bunde & Upmeyer, 

 the well-known Milwaukee jewelers. 1 



In 1893 Messrs. Bunde & Upmeyer purchased from Mrs. G. 

 Pufahl a white diamond of about 2 carats weight, said to have 

 been found at Burlington, Racine county, Wisconsin. Little was 

 learned at the time of the circumstances attending the finding of 

 this stone, and the writer's subsequent attempts to get into com- 

 munication with Mrs. Pufahl, though kindly assisted by Messrs. 

 Bunde & Upmeyer, have not been successful. Like most of the 

 others, this diamond was probably found in the glacial drift. 2 



The latest diamond to come from the region under considera- 

 tion was found so recently that nothing is in print concerning it, 

 except in the newspapers. It is a diamond of purest water, 

 weighing 6 carats, and was found in 1897 Dv two small daugh- 

 ters of J. R. Taylor, at the town of Milford, Clermont county, 

 Ohio. It is now owned by Herman Keck, of Cincinnati, and has 

 recently been cut into the form of a brilliant. Before cutting a 

 cast was taken of it and the stone is now being studied by Pro- 

 fessor Thomas N. Norton, of the University of Cincinnati. 



It is seen from the foregoing that no less than seventeen well- 

 identified diamonds, varying in weight from ]/ 2 carat to over 

 21 carats, have been discovered in the region of the Great Lakes 

 of North America. That a considerable number of others have 

 been found which have not been reported because they have
