Lowell was able to deal with money

"Like wealthy men, not knowing what they give."

more probably he felt a sacredness in the money got by literature, which
the literary man never quite rids him self of, even when he is not a
poet, and which made him wish to dedicate it to something finer than the
every day uses. He lived very quietly, but he had by no means more than
he needed to live upon, and at that time he had pecuniary losses. He was
writing hard, and was doing full work in his Harvard professorship, and
he was so far dependent upon his salary, that he felt its absence for the
year he went abroad. I do not know quite how to express my sense of
something unworldly, of something almost womanlike in his relation to
money.

He was not only generous of money, but he was generous of himself, when
he thought he could be of use, or merely of encouragement. He came all
the way into Boston to hear certain lectures of mine on the Italian
poets, which he could not have found either edifying or amusing, that he
might testify his interest in me, and show other people that they were
worth coming to. He would go carefully over a poem with me, word by
word, and criticise every turn of phrase, and after all be magnanimously
tolerant of my sticking to phrasings that he disliked. In a certain line

"The silvern chords of the piano trembled,"

he objected to silvern. Why not silver? I alleged leathern, golden, and
like adjectives in defence of my word; but still he found an affectation
in it, and suffered it to stand with extreme reluctance. Another line of
another piece:

"And what she would, would rather that she would not"

he would by no means suffer. He said that the stress falling on the last
word made it "public-school English," and he mocked it with the answer a
maid had lately given him when he asked if the master of the house was at
home. She said, "No, sir, he is not," when she ought to have said "No,
sir, he isn't." He was appeased when I came back the next day with the
stanza amended so that the verse could read:

"And what she would, would rather she would not so"

but I fancy he never quite forgave my word silvern. Yet, he professed
not to have prejudices in such matters, but to use any word that would
serve his turn, without wincing; and he certainly did use and defend
words, as undisprivacied and disnatured, that made others wince.

He was otherwise such a stickler for the best diction t
