     With a good shopping position and the right amount (数量) of money, any educated person ought to

be able to make a living out of a bookshop. It is not a difficult trade to learn and the large chain-stores

can never force the small bookseller out of existence as they have done to the corner shop. But the hours

of work are very long-I was only doing a part-time job, but my boss put in a seventy-hour week,besides

regular journeys out of shopping hours to buy books.

     The real reason why I should not like to be back in the book trade for life, however, is that while I was

in it I lost my love of books. A bookseller cannot always tell the truth about his books, and that gives him

a dislike for them. There was a time when I really did love books-loved the sight and smell and feel of

them-if they were fifty or more years old, that is. Nothing pleased me quite so much as to buy a bargain lot

of them on sale for several pounds. There is a peculiar flavour (独特的味道) about the unexpected books

you pick up in that kind of collection: little-known eighteenth-century poets, or out-of-date geography

books. For occasional (偶尔的) reading-in your bath, for example, or late at night when you are too tired

to go to bed-there is nothing as good as a very old picture story-book.

     But as soon as I went to work in the bookshop I stopped buying books. Seen in a mass. five or ten

thousand at a time, books were dull and even a little tiresome. Nowadays I do buy one occasionally, but

only if it is a book that I want to read and can't borrow, and I never buy rubbish.
