The foregoing comparison, relates however, simply to passengers killed in accidents for which they are in no degree responsible. When, however, the question reverts to the general cost in life and limb at which the railroad systems are worked and the railroad traffic is carried on to the entire communities served, the comparison is less favorable to Massachusetts. Taking the eight years of 1871-8, the British returns include 30,641 cases of injury, and 9,113 of death; while those of Massachusetts for the same years included 1,165 deaths, with only 1,044 cases of injury; in the one case a total of 39,745 casualties, as compared with 2,209 the other. It will, however be noticed that while in the British returns the cases of injury are nearly three-fold those of death, in the Massachusetts returns the deaths exceed the cases of injury. This fact in the present case cannot but throw grave suspicion on the completeness of the Massachusetts returns. As a matter of practical experience it is well known that cases of injury almost invariably exceed those of death, and the returns in which the disproportion is greatest, if no sufficient explanation presents itself, are probably the most full and reliable. Taking, therefore, the deaths in the two cases as the better basis for comparison, it will be found that the roads of Great Britain in the grand result accomplished seventeen-fold the work of those of Massachusetts with less than eight times as many casualties; had the proportion between the results accomplished and the fatal injuries inflicted been maintained, but 536 deaths instead of 1,165 would have appeared in the Massachusetts returns. The reason of this difference in result is worth looking for, and fortunately the statistical tables are in both cases carried sufficiently into detail to make an analysis possible; and this analysis, when made, seems to indicate very clearly that while, for those directly connected with the railroads, either as passengers or as employés, the Massachusetts system in its working involves relatively a less degree of danger than that of Great Britain, yet for the outside community it involves very much more. Take, for instance, the two heads of accidents at grade-crossings and accidents to trespassers, which have been already referred to. In Great Britain highway grade-crossings are discouraged. In Massachusetts they are practically insisted upon. The results of the policy pursued may in each case be read with sufficient distinctness in the bills of mortality. During the years 1872-7, of 1,929 casualties to persons on the railroads of Massachusetts, no less than 200 occurred at highway grade crossings. Had the accidents of this description in Great Britain been equally numerous in proportion to the larger volume of the traffic of that country, they would have resulted in over 3,000 cases of death or personal injury; they did in fact result in 586 such cases.
