METEOKITES OF NORTH AMERICA. 47 



Ward removed about 11 pounds of the meteorite and distributed it among various col- 

 lections. The remainder of the mass lies in its original position. 



A model of the mass was exhibited by the U. S. National Museum at the Louisiana Pur- 

 chase Exposition.

BALD EAGLE. 



Lycoming County, Pennsylvania. 



Here also Williamsport. 



Latitude 41° W N., longitude 77° 3' W. 



Iron. Medium oetahedrite (Om) of Brezina. 



Found 1891; described 1892. 



Weight, 3.3 kgs. (7 lbs.). 



This iron is described by Ward 2 as having been found about September 25, 1891, by some 

 Italian laborers on the east side of Bald Eagle Mountain, 7 miles south of Williamsport, Penn- 

 sylvania. It was covered with a fungous growth, as were the stones under which it was buried 

 to the depth of several feet. Nothing is known as to the time of its faU, although the stones 

 under which it lay buried have not been sensibly moved since the valley of the river on whose 

 banks it was found — the Susquehanna — has been inhabited by white men. 



Its weight was 3.3 kgs. (7 pounds 1 ounce). 



In form it resembled a human foot, the flat face corresponding to the sole, measuring 16.6 

 by 8 cm., with a height at the heel of 14 cm. It was very irregular in outline and was covered 

 with many rough notches and depressions, few of which are well-defined pittings. The upper 

 part of the "ankle" only had a well smoothed surface with a fine granulation akin to a "skin" 

 or crust. The surface was covered with a reddish brown iron rust, which scaled off easily 

 and showed the bright metal beneath. 



As far as can be learned this is the only specimen of the fall that has been found. 



Two cavities were seen on the back above the "heel," one round and three-eighths of an 

 inch in depth and diameter; the other a parallelogram, half as deep and three-fourths of an inch 

 long by one-third of an inch wide, and both having vertical walls — cavities probably produced 

 by the erosion of troilite nodules. On top of the front part of the "foot" was a deep cavity, 

 due to the folds of the iron, which passed nearly through to the sole. The sole was very flat, 

 which permitted the cutting of a slice from it like the "sole" of a shoe. Sharp and peculiar 

 Widmannstatten figures were easily etched on the polished surface with dilute acid, showing 

 a typically octahedral structure. The figures were composed mainly of short kamacite blades, 

 with an average thickness of about 1 mm. and from 5 to 10 mm. in length, which departed 

 from the usual angular figures, being largely curved or shake-like in form and forming a pattern 

 resembling floss or tangled yarn. Many of these kamacite blades were club shaped. The patches 

 of plessite were minute, sometimes showing clearly the alternate layers of kamacite and taenite.
