Olivier, on his part, used to write to Christophe's mother without letting him know. He gave Louisa news of her son, and told her how fond he was of him and how he admired him. Louisa would send Olivier awkward, humble letters in which she thanked him profusely: she used always to write of her son as though he were a little boy. After a period of fond semi-silence--"a delicious time of peace and enjoyment without knowing why,"--their tongues were loosed. They spent hours in voyages of discovery, each in the other's soul. They were very different, but they were both pure metal. They loved each other because they were so different though so much the same. Olivier was weak, delicate, incapable of fighting against difficulties. When he came up against an obstacle he drew back, not from fear, but something from timidity, and more from disgust with the brutal and coarse means he would have to employ to overcome it. He earned his living by giving classes, and writing art-books, shamefully underpaid, as usual, and occasionally articles for reviews, in which he never had a free hand and had to deal with subjects in which he was not greatly interested:--there was no demand for the things that did interest him: he was never asked for the sort of thing he could do best: he was a poet and was asked for criticism: he knew something about music and he had to write about painting: he knew quite well that he could only say mediocre things, which was just what people liked, for there he could speak to mediocre minds in a language which they could understand. He grew disgusted with it all and refused to write. He had no pleasure except in writing for certain obscure periodicals, which never paid anything, and, like so many other young men, he devoted his talents to them because they left him a free hand. Only in their pages could he publish what was worthy of publicity.
