His labors also included " personal visitation of every spot of interest and nearly every person of advanced age.'' In addition to his History of the county, he published a " Guide to New Kochelle " and a " History of the Protestant Episcopal Church in Westchester County." At the time of his death he had nearly completed a revision of his History of the county, which was issued under the editorship of his brother, the Rev. C. W. Bolton, of New Kochelle, in 1881. On the 4th of December, 1851, occurred the first serious railway accident in the history of the county. This was of a decidedly sensational nature. An afternoon up train from New York was stopped by the conductor above Croton to put off two men who did not pay their fare, and was run into by an engine without cars, several passengers suffering injury. Another up train which followed it -- an express train -- was switched off to the west track and halted to render assistance; whereupon it was run into by a down train, resulting in more casualties. This double accident caused much newspaper comment. The Village of Tarrytown was the scene of a notable monument dedication on the 7th of October, 1853. On the spot where Major Andre was captured by Paulding, Williams, and Van Wart, September 23, 1780, a monument in commemoration of that event was unveiled with much ceremony, the governor of the State and other distinguished guests being in attendance. In a previous chapter the particulars of this event and also of the dedication of the " new " monument on the same spot in 1880 have been given (see p. 493). The burning of the Hudson River steamboat " Henry Clay " on the 28th of July, 1857, the most terrible disaster of that period, is vividly remembered by many citizens of Yonkers still living.
