On (i Recent Diamond Find in Wisconsin. — Hobbs. 33 
stone is about 16 carats. Col. Boynton has given me the fol- 
lowing facts concerning the section of material penetrated by 
the Eagle well in which this stone was found. Loose gravel 
extends from the surface to a depth of 25 feet. This is fol- 
lowed by 45 feet of clay. Below the clay is a layer 6 feet 
thick of hard yellow "matrix.'* which is doubtless gravel or 
clay cemented by oxide of iron. It was in this material that 
the diamond was found. Below it the well was sunk for two 
feet through clean gravel. Two small diamonds are said to 
have been subsequently taken from the well. There is also a 
report of a stone that is said to have been found when the 
well was begun in 1868. It was the size of a robin's egg. 
Parties who saw both this stone and the Eagle diamond claim 
that the onlj- noticeable difference was in size. This stone 
may have been a diamond, but the evidence is insufficient. 
While prospecting for gold in the summers of 1887, 1888, 
and 1889, Mr. G. H. Nichols of Minneapolis and two compan- 
ions found a number of small diamonds in the bed of Plum 
creek in Rock Elm township, Pierce county.* Three of these 
stones, weighing 25-32. 7-16, and 3-32 of a carat respectively, 
were sent to Mr. Kunz for examination. All were found to 
be hexoctahedra and either white or yellowish. 
I am informed by Col. Boynton that a diamond very much 
like the Eagle diamond was found in 1NN4 by Heniy Endlich 
on his farm at Kollsville near West Bend in Washington 
county. Mr. Boynton describes this stone as wine 3'ellow and 
of the same form as the Eagle diamond. It was harder than 
emery and weighed 21]- carats. The same hard yellow fer- 
ruginous "matrix'" which is found in the Eagle well occurs on 
Mr. Endlieh's farm at Kollsville. I learn by correspondence 
that Mr. Endlich has since died and his family has moved 
away from Kollsville. I have not yet Succeeded in getting 
into communication with any member of the family, but I 
think there can be little doubt that the stone found by .Mr. 
Endlich was a diamond.f At the time Mr. Boynton examined 
the stone he was in possession of the Eagle diamond, and he

ef Kewaskum, Wis., now has the stone, bul I have had no opportunitj 
to examine it.
