318 G. F. Kunz — New American Meteorites. 



the mound specimens the body of the meteorite is iron, in 

 which are imbedded circular masses or crystals of olivine. 

 The fact that in connection with the large Kiowa masses a 

 number of small portions, weighing from half a pound to six 

 pounds each, were found, makes it v.ery probable that a small 

 mass, of perhaps three or four pounds, had been conveyed by 

 the Indians to the Ohio valley. Probably the two ear-rings in 

 the collection of Mr. "Warren K. Moorhead, recently found by 

 him at Fort Ancient, Ohio, may have been made from a part 

 of the mass weighing 767*5 grams, which is now in the Har- 

 vard University collection. 



I must here express my indebtedness to Professor F. H. 

 Snow for information, and particularly to Professor Robert 

 Hay for aiding me in procuring many of the meteorites and 

 assisting greatly to obtain exact data by visiting the place of 

 discovery, and to secure the illustrations ; as also to Mr. L. G. 

 Eakins for making the analyses, and to Professor F. W. Clarke, 

 of the U. S. Geological Survey, for his courtesy in having 

 them made at the Survey Laboratory. 



2. On the Winnebago County, Iowa, Meteorite*' 



On Friday, May 2, 1890, at 5.15 P. M., standard "Western 

 time, a meteor was observed over a good part of the State of 

 Iowa. It is described as a bright ball of fire, moving from 

 west to east, leaving a trail of smoke which was visible for 

 from ten to fifteen minutes ; it was accompanied by a noise, 

 likened to that of heavy cannonading or of thunder, and many 

 people rushed to their doors, thinking it was the rumbling of 

 an earthquake. Substantiated reports have been received 

 from DesMoines, Mason City, Fort Dodge, Emmetsburg, Al- 

 gonia, Ruthven, Humboldt, Britt, Garnet, Grinnell, Sioux 

 City and Forest City; the noise was also heard at Chamber- 

 lain, South Dakota. Some of these places were distant more 

 than a hundred miles from the point where the meteor fell. 

 It exploded about eleven miles northwest of Forest City, at 

 Leland, Winnebago County, in the center of the northern 

 part of Iowa, latitude 43° 15', longitude 93° 45' west of 

 Greenwich, near the Minnesota State line, and the fragments 

 were scattered over an area one mile wide and nearly two miles 

 long. Up to the present time, there have been found masses 

 weighing respectively eighty pounds, sixty-six pounds and ten 

 pounds, two of four pounds and about five hundred fragments 

 weighing from one-twentieth of an ounce to twenty ounces 

 each, while a part of the mass is believed to have passed over 

 into Minnesota. The pieces are all angular, with rounded 

 edges.
