Admitting, therefore, that ill luck or hard fortune must fall to the lot of certain unascertainable persons, yet the chances of incurring that ill fortune are so small that they are not materially increased by any amount of traveling which can be accomplished within the limits of a human life. So far from exhausting a fair average immunity from accident by constant traveling, the statistics of Massachusetts during the last eight years would seem to indicate that if any given person were born upon a railroad car, and remained upon it traveling 500 miles a day all his life, he would, with average good fortune, be somewhat over 80 years of age before he would be involved in any accident resulting in his death or personal injury, while he would attain the highly respectable age of 930 years before being killed. Even supposing that the most exceptional average of the Revere year became usual, a man who was killed by an accident at 70 years of age should, unless he were fairly to be accounted unlucky, have accomplished a journey of some 440 miles every day of his life, Sundays included, from the time of his birth to that of his death; while even to have brought him within the fair liability of any injury at all, his daily journey should have been some 120 miles. Under the conditions of the last eight years his average daily journey through the three score years and ten to entitle him to be killed in an accident at the end of them would be about 600 miles. CHAPTER XXII. THE RAILROAD DEATH RATE. In connection with the statistics of railroad casualties it is not without interest to examine the general vital statistics of some considerable city, for they show clearly enough what a large degree of literal truth there was in the half jocose proposition attributed to John Bright, that the safest place in which a man could put himself was inside a first-class railroad carriage of a train in full motion. Take the statistics of Boston, for instance, for the year 1878. During the four years 1875-8, it will be remembered, a single passenger only was killed on the railroads of Massachusetts in consequence of an accident to which he by his own carelessness in no way contributed.[27] The average number of persons annually injured, not fatally, during those years was about five. [27] This period did not include the Wollaston disaster, as the Massachusetts railroad year closes on the last day of September. The Wollaston disaster occurred on the 8th of October, 1878, and was accordingly included in the next railroad year.
