Young Betty Craig, a friend of Jack's sister Florence, bets her that she can disguise herself as a man and get a job at the ranch, fooling all the cowboys As "Bob Craig", she gets hired, but although Jack and the cowboys aren't fooled by her "disguise", they decide to have some fun with "Bob" and put her through a series of practical jokes to test "Bob's" mettle.

Joe's wound is not serious and that night he takes his place as fireman on the freight.
