8 September 1910

Amos Arnold's sister, Eunice Abigail Arnold (also known as "Abigail"), married Jehial B. White in upstate New York. They made their home in Peru, New York. J. B. and Abigail White had one child, Mary, affectionately nicknamed "Pet" by her family.
On September 8, 1910, Mary is returning home from "the fair" and is fatally injured after the car in which she is riding is hit by a train at a crossing about three mile south of Peru.  Mary was 51 years old.
Mary was married at the time of her death to Hiram Heyworth and had two daughters, Abigail and Sarah.

One of the saddest automobile accidents which has ever occurred in this section took place at the crossing of the Chateaugay railroad on the Peru road, about three miles south of this city, shortly before six o'clock last evening, resulting in the instant death of Mrs. H. E. Heyworth of Peru and serious injury of Russell Clark and Miss Bessie Clark, children of Datus Clark of the same village.
Mr. and Mrs. Heyworth and Mr. Clark and his son and daughter had spent the day at the fair and were returning home in Mr. Clark's automobile, which was driven by Russell Clark.  Mr. Heyworth occupied the front seat with the chauffeur, Miss Clark the center seat and Mrs. Heyworth and Mr. Clark the rear seat.  At least two other automobiles were on the road with the Clark car and one of these had passed over the crossing and young Clark, evidently thinking that no train was approaching started to follow.  When within a few feet of the crossing he saw the passenger train from Saranac Lake, due here at six o'clock, bearing down upon him. Realizing the danger he applied the emergency brakes and turned his car to the east, hoping to avoid an accident.  He was too late, however, and his automobile struck the side of the baggage car as it rapidly passed by.  All of the occupants were thrown out, Mr. Heyworth falling near his wife.  He escaped with practically no injuries and when he turned to where his wife lay he found that she was dead.  A gash about four inches in length had been cut in her forehead, indicating that she had in some way struck the baggage car as she flew through the air.
Miss Clark was unconscious when picked up and remained so far some time.  Her brother was suffering great pain from a dislocated shoulder.  The brother and sister were hurriedly brought to the post hospital, where an examination showed that Miss Clark's shoulder was dislocated, her spine probably injured and she also suffered other injuries.  Mr. Clark, like Mr. Heyworth, escaped without injury.  The remains of Mrs. Heyworth were as soon as possible taken to her home in Peru. 
The automobile was practically demolished in its collision with the train.  Conductor Long, who was in charge of the train, stopped within a short distance of the accident and offered every possible assistance to the unfortunate people.
