of February 16 over northern Kansas was just that, inasmuch as meteorites have been recovered from it." There were found, beginning April 24, first several smaller fragments up to one of 4 1/2 pounds. Then a disturbed spot in a clover field led to the digging up of a piece of some 109 pounds embedded about two feet in the soil. The stone is what is termed as an "achondrite", a technical name for an unusual type of stony meteorite. It is reported to be of a type which will deteriorate rapidly.

A photograph of the trail of the meteor, made by amateur photographer Duane N. Wray of Norton, shows the vapor trail left in the sky by the explosion of a meteor which was seen in Oklahoma, New Mexico, Colorado, Kansas, and ebraska. It was made at Wray's home, nine miles north of Norton, just four minutes after the meteor exploded. A smudge of blue-white smoke remained in the sky for an hour February 18th. This photograph is in file under Incident #101.
