SUPERMAN’S GIRL FRIEND, LOIS LANE 124 launches a new letter column in addition to the regular "Letters to Lois and Rose" column edited by E. Nelson Bridwell.
The new column is hosted by the Mystery Columnist, Alexander the Great, and gets the title "The Boneyard" in issue 125.
Why Boneyard? Presumably because an error is called a "boner" (although the other meaning of boner was quite well known at this time). So this is a column for letters about mistakes and other curiosities that fans picked up on.

SUPERMAN’S GIRL FRIEND, LOIS LANE 125 (August 1972)--1st story, "Death Rides the Wheels" by Bates, Rosenberger and Colletta:
Kristin Cutler behaves oddly in front of her roommates. And the biker gang, the Spike Helmets, are revealed to be led by a Nazi. Lois suspects that Kristin is also a Nazi.
Note: Don't get your hopes up Lois. The Kristin Cutler subplot goes nowhere after this. One less Pulitzer Prize for you.
