of the island of Laputa, describes some philosophers there who were so
wrapped up and absorbed in their abstruse speculations, that they would
have forgotten all the common and necessary duties of life, if they had
not been reminded of them by persons who flapped them, whenever they
observed them continue too long in any of those learned trances. I do not
indeed suspect you of being absorbed in abstruse speculations; but, with
great submission to you, may I not suspect that levity, inattention, and
too little thinking, require a flapper, as well as too deep thinking? If
my letters should happen to get to you when you are sitting by the fire
and doing nothing, or when you are gaping at the window, may they not be
very proper flaps, to put you in mind that you might employ your time
much better? I knew once a very covetous, sordid fellow, who used
frequently to say, "Take care of the pence; for the pounds will take care
of themselves." This was a just and sensible reflection in a miser. I
recommend to you to take care of the minutes; for hours will take care of
themselves. I am very sure, that many people lose two or three hours
every day, by not taking care of the minutes. Never think any portion of
time whatsoever too short to be employed; something or other may always
be done in it.

While you are in Germany, let all your historical studies be relative to
Germany; not only the general history of the empire as a collective body;
but the respective electorates, principalities, and towns; and also the
genealogy of the most considerable families. A genealogy is no trifle in
Germany; and they would rather prove their two-and-thirty quarters, than
two-and-thirty cardinal virtues, if there were so many. They are not of
Ulysses' opinion, who says very truly,

----Genus et proavos, et qua non fecimus ipsi;
Vix ea nostra voco.
