He was reelected to the twelve succeeding Congresses and served until his death in Houston, Texas.

In 1970 the Izaak Walton League of America bestowed its highest honor, the Founders' Award, to Saylor "for two decades of unprecedented leadership in the Congress of the United States for sound resource management, the preservation of natural scenic and cultural values, the maintenance of a quality environment, and the unalienable right of citizens to be involved in resources and environmental decisions.

While the operation was reported to be a success, he had a heart attack in his hospital room shortly after midnight on October 28 and died at the age of 65.
