whole, intermediate between typical tracliytes and andesites, as recognized by 

 F. D. Adams from a few specimens in 1876. Among the dikes and sills there 

 is a tendency to shade off toward the basalts without developing typical and 

 markedly basic types. A greatly contrasted variety, less frequently seen in 

 both sills and dikes, is the minette, already described by Weed and Pirsson 

 from a specimen gathered by Dr. Dawson from an outlying dike to the north 

 of East Butte. One sill of minette is packed with inclusions of Precambrian 

 rocks brought up from a great depth. One or two pipes have afforded still 

 different varieties of igneous rocks. Contact zones have been developed by 

 the main laccolith of East Butte from the Madison limestone of the Carbon- 

 iferous with attendant deposits of magnetic and specular iron ore.

CUUBERLAXD FALL8, KENTUCKY, METEORITE 

 BY ARTHUR M. MILLFJR 



(Al)Stract) 



The paper describes the phenomena and incidents connected with the 

 meteoric fall in McCreary County, Kentucky, near the Falls of the Cumber- 

 land, on the McCreary-Whitley County line, at midday, on April 9, 1919. 



Recognizing that the event chronicled in the local newspapers of south- 

 eastern Kentucky as an earthquake was a falling meteorite, the writer im- 

 mediately took steps to obtain information concerning it with a view to deter- 

 mining its trajectory and obtaining as much of the meteorite itself as possible. 

 The methods employed in this investigation are recounted. A summary of the 

 facts obtained is as follows : 



The meteor in its fall was seen or heard throughout an area of about 22,700 

 square miles, extending from Neubert, 12 miles south of Knoxville, Tennessee, 

 on the south, to Lexington, Kentucky, on the north ; and from Rogersville, 

 Tennessee, on the east, to Jamestown, Kentucky, on the west. In that part of 

 this region lying in Tennessee the sky was clear and the meteor, shining with 

 a light which exceeded in brightness that of the sun, was seen descending 

 toward the northwest. In that portion of Kentucky near where it fell the 

 sky was cloudy, and the inhabitants were advised of its presence only by the 

 deafening sounds produced by the concussions. Farther north in the area the 

 sky was again clear, and people both saw the descending body in the south 

 and heard the detonations as it neared the earth. The horizontal component 

 in its trajectory is computed to be north .31 degrees west. In its passage over 

 Kentucky till it fell it paralleled on the east side the line of the Queen and 

 Crescent Railroad. 



In this stretch the signal-tower men along the line of railroad heralded its 

 coming ahead by telephone, after the manner of keeping track of an "extra." 

 At Coal Creek, Tennessee, a little east of south of Cumberland Falls and 45 

 miles distant, a telegraph operator saw it disappear to the northwest at 12.21 

 p, m, (daylight-saving schedule time for this meridian). At Tatesville, Ken- 

 tucky, about 13 miles northwest of Cumberland Falls, it was heard by a 

 towerman at 12.27. The telegraph operator at Danville, 50 miles north of
