In the prior episode "It Tolls for Thee", which aired only one week earlier, the year as shown when the Virginian writes a receipt is 1884. In this episode, the Virginian narrates at the opening that the year is 1897. This a gap of 13 years but none of the characters have aged and Judge Garth still owns Shiloh.
Then they have the gang head off to fight the Spanish Americans War in 1898 in a later Virginian.
