Up to this point, the statistics and experience of Massachusetts only have been referred to. This is owing to the fact that the railroad returns of that state are more carefully prepared and tabulated than are those of any other state, and afford, therefore, more satisfactory data from which to draw conclusions. The territorial area from which the statistics are in this case derived is very limited, and it yet remains to compare the results deduced from them with those derived from the similar experience of other communities. This, however, is not an easy thing to do; and, while it is difficult enough as respects Europe, it is even more difficult as respects America taken as a whole. This last fact is especially unfortunate in view of the circumstance that, in regard to railway accidents, the United States, whether deservedly or not, enjoy a most undesirable reputation. Foreign authorities have a way of referring to our "well-known national disregard of human life," with a sort of complacency, at once patronizing and contemptuous, which is the reverse of pleasing. Judging by the tone of their comments, the natural inference would be that railroad disasters of the worst description were in America matters of such frequent occurrence as to excite scarcely any remark. As will presently be made very apparent, this impression, for it is only an impression, can, so far as the country as a whole is concerned, neither be proved nor disproved, from the absence of sufficient data from which to argue. As respects Massachusetts, however, and the same statement may perhaps be made of the whole belt of states north of the Potomac and the Ohio, there is no basis for it. There is no reason to suppose that railroad traveling is throughout that region accompanied by any peculiar or unusual degree of danger.
