From the fact that the ridged side is so free from crust and 
the flat side so thickly coated; that the ridged side is covered 
with strize and marks of flowing, and the other has so few 
marks of this kind, and from the fact that at the edges, espe- 
cially at the indentation the back looks as though a flame 
had come from the other side—from all these facts the writer 
concludes that after entering our space the iron traveled with 
the ridged surface forward (see fig. 1, Plate XIII), the iron 
burning so rapidly as to be torn off, leaving part of the surface 
bright. The flame thus passed over the sides, and the indented 
edge being downward, the flame was driven upward as the iron 
advanced. The flat side, not being so much exposed, the iron 
was not so completely consumed, hence a crust and large but 
shallow pittings. These conditions would perhaps have been 
entirely different had the mass been round or thicker, for it 
evidently moved as straight as possible without rotating at all. 
That it was found in the hole with the flat side down was due 
perhaps to the fact that having lost its impetus it turned in 
falling, or, as Professor Newton suggests, it may have been 
turned by striking the tree, and then have fallen downward 
almost in a straight line. 
As the iron only penetrated to a depth of three feet (90™) 
the earth where it struck must have been very compact and the 
force of the body itself nearly spent. The Agram iron pene- 
trated 14 to 15 feet (425~450™) in a freshly ploughed field, 
which shows that in the case of that meteorite there must have 
been considerable force left, the small mass falling very near it. 
The Mazapil mass, one tenth of the weight, penetrated only 12 
inches (80%). 
I must herewith thank Mayor B. Caraway and Ool. J. C. 
Betten for information furnished me, and Professor F. W. 
Clarke and Mr, J. E. Whitfield for their courtesy and for the 
analysis.
