W. FE. Hidden—Mazapil Meteorie tron. 223 
Looking up to the sky we saw from time to time exhalations or 
stars, which soon went out, but without noise. We returned 
after a little and found in the hole a hot stone, which we could 
barely handle, which on the next day looked like a piece of iron; 
all night it rained stars but we saw none fall to the gr ound as 
they seemed to be extinguished while still very high up.’ 
“The above is the simple recital of the ranchman, and the 
uranolite which fell is the one I send to you. From the numer- 
ous questions I have asked Sr. Mijares, I am convinced that there 
was no explosion or breaking up on falling. Others who saw 
the phosphorescence, etc., were Luz Sifuentes, Pascual Saenz, 
Miguel Martinez, Justo Lopez and some whose names I have not 
obtained.

“Upon visiting the place of the fall (see accompanying map of 
the northern section of Mazapil in the State of Zacatecas) I was 
particular to examine the earth in and around the hole, and by 
careful search and: washing the earth I found a few small bits of 
iron, which must have become detached from the uranolite when 
it penetrated the earth. 
‘““The hole was thirty centimeters deep. Probably the hehe 
which was seen came from the volatilization of the surface of the 
celestial body due to the high temperature acquired by friction 
with the atmosphere, and of this volatilized matter falling to the 
earth as an incandescent powder.”
