The Spur Question

[RJNorton]

Conger testified that he took a spur from Booth's remains. He was asked about it at the trial:

Q. [Exhibiting a spur.] Is that the spur?
A. I cannot swear that it is positively; I turned the spur over to Mr. Stanton; and, if that is the spur that has been in his department, its history can be easily traced.
Q. There was a spur?
A. There was a spur very similar to that: I judge that to be the one; but I cannot say so with certainty.
