then disgusted with
its repetition. Go on delivering it, and the disgust passes off, until,
after one has repeated it a hundred or a hundred and fifty times, he
rather enjoys the hundred and first or hundred and fifty-first time,
before a new audience. But this is on one condition,--that he never lays
the lecture down and lets it cool. If he does, there comes on a
loathing for it which is intense, so that the sight of the old battered
manuscript is as bad as sea-sickness.

A new lecture is just like any other new tool. We use it for a while
with pleasure. Then it blisters our hands, and we hate to touch it.
By-and-by our hands get callous, and then we have no longer any
sensitiveness about it. But if we give it up, the calluses disappear;
and if we meddle with it again, we miss the novelty and get the
blisters.--The story is often quoted of Whitefield, that he said a
sermon was good for nothing until it had been preached forty times.
A lecture doesn't begin to be old until it has passed its hundredth
delivery; and some, I think, have doubled, if not quadrupled, that
number. These old lectures are a man's best, commonly; they improve by
age, also,--like the pipes, fiddles, and poems I told you of the other
day. One learns to make the most of their strong points and to carry off
their weak ones, to take out the really good things which don't tell on
the audience, and put in cheaper things that do. All this degrades
him, of course, but it improves the lecture for general delivery. A
thoroughly popular lecture ought to have nothing in it which five
hundred people cannot all take in a flash, just as it is uttered.

----No, indeed,--I should be very sorry to say anything disrespectful
of audiences. I have been kindly treated by a great many, and may
occasionally face one hereafter. But I tell you the _average_ intellect
of five hundred persons, taken as they come, is not very high. It may be
sound and safe, so far as it goes, but it is not very rapid or profound.
A lecture ought to be something which all can understand, about
something which interests everybody. I think, that, if any experienced
lecturer gives you a different account from this, it will probably be
one of those eloquent or forcible speakers who hold an audience by the
charm of their manner, whatever they talk about,--even when they don't
talk very well.

But an _average_, which was what I meant to speak about, is one of the
most extraordinary subjects of o
