The Son of His Father is a 1917 American silent drama film directed by Victor Schertzinger and written by Ridgwell Cullum.

Gordon meets Silas Mallinsbee (Nichols) at Buffalo Falls, where the son is eager to have the railroad build a station at that point.

Mallinsbee cannot come to an agreement with David Slosson (McKim), the representative of Gordon's father.

Using his father's code, Gordon orders a train crew to come to Buffalo Falls and construction of the station begins.

After work is well underway, Gordon brings his report to his father, who is proud of his son.
