And you are to observe that this comparison is a strictly just comparison. We contrast not the whole community, old and young, with those who must necessarily have attained manhood before they are a class at all; but adults with adults, graduates with those of other avocations who have arrived at the period of twenty years. Neither do we compare the bright and peculiar luminaries of Harvard with the mass of men,--though, in fact, it is well known that the best scholars live the most years,--but we compare the whole body of the graduates, bright and dull, studious and unstudious, with the whole body of the community. * * * * * To the array of evidence which may be brought from all the registries of all the states and universities under heaven, some may triumphantly exclaim, "Statistics are unworthy of trust." "To lie like statistics," "false as a fact," these are the stalest of witticisms. But the objection to which they give point is practically frivolous. Grant that statistics are to a certain degree doubtful, are they not the most trustworthy evidence we have? And in the question at issue, are they not the only evidence which has real force? And allowing their general defectiveness, how shall we explain, that, though gathered from all sides and by all kinds of people, they so uniformly favor education? Why, if they must err, do they err so pertinaciously in one direction? How does it happen, that, summon as many witnesses as you please, and cross-question them as severely as you can, they never falter in this testimony, that, where intelligence abounds, there physical vigor does much more abound? that, where education is broad and generous, there the years are many and happy?
