and never lost his eyesight nor used spectacles. He got on horseback

Everything depends on habit. Old people can do, of course, more or less
well, what they have been doing all their lives; but try to teach them
any new tricks, and the truth of the old adage will very soon show
itself. Mr. Henry Hastings had done nothing but hunt all his days, and
his record would seem to have been a good deal like that of Philippus
Zaehdarm in that untranslatable epitaph which may be found in "Sartor
Resartus." Judged by its products, it was a very short life of a hundred
useless twelve months.

It is something to have climbed the white summit, the Mont Blanc of
fourscore. A small number only of mankind ever see their eightieth
anniversary. I might go to the statistical tables of the annuity and
life insurance offices for extended and exact information, but I prefer
to take the facts which have impressed themselves upon me in my own
career.

The class of 1829 at Harvard College, of which I am a member, graduated,
according to the triennial, fifty-nine in number. It is sixty years,
then, since that time; and as they were, on an average, about twenty
years old, those who survive must have reached fourscore years. Of the
fifty-nine graduates ten only are living, or were at the last accounts;
one in six, very nearly. In the first ten years after graduation, our
third decade, when we were between twenty and thirty years old, we lost
three members,--about one in twenty; between the ages of thirty and
forty, eight died,--one in seven of those the decade began with; from
forty to fifty, only two,--or one in twenty-four; from fifty to sixty,
eight,--or one in six; from sixty to seventy, fifteen,--or two out of
every five; from seventy to eighty, twelve,--or one in two. The greatly
increased mortality which began with our seventh decade went on steadily
increasing. At sixty we come "within range of the rifle-pits," to borrow
an expression from my friend Weir Mitchell.

Our eminent classmate, the late Professor Benjamin Peirce, showed by
numerical comparison that the men of superior ability outlasted the
average of their fellow-graduates. He himself lived a little beyond his
threescore and ten years. James Freeman Clarke almost reached the age
of eighty. The eighth decade brought the fatal year for Benjamin Robbins
Curtis, the great lawyer, who was one of the
