During the summer of 1873 a number of cadets, who were on furlough, visited Mammoth Cave. While there they noticed on the wall, written in pencil, the name of an officer who was an instructor in Spanish at West Point. One of them took occasion to add to the inscription the following bit of information:

"Known at the U. S. Military Academy as the 'Spanish
Inquisition.'"

A number of cadets accosted a plebe, who had just reported in May, 1874, and the following conversation ensued:

"Well, mister, what's your name?"

"John Walden."

"Sir!" yelled rather than spoken.

"John Walden."

"Well, sir, I want to see you put a 'sir' on it," with another yell.

"Sir John Walden," was the unconcerned rejoinder.

Now it was not expected that the "sir" would be put before the name after the manner of a title, but this impenetrable plebe put it there, and in so solemn and "don't-care" a manner that the cadets turned away in a roar of laughter.
