And furthermore . . .

Can the Harvard Classics and The Home Forum both be wrong? Thanks to Alberta Robison of Camarillo, Calif., for gently raising the question. She asks if the word ''monetary'' should really be ''momentary'' in our brief (mis)quotation from Matthew Arnold's comment on good literature (Oct. 26): ''. . . it will never lose currency with the world, in spite of monetary appearances . . . .'' Our source was the Harvard Classics, which used ''monetary,'' and we evidently nodded over its punning link with ''currency.'' But we have now found Arnold's essay, ''The Study of Poetry,'' elsewhere - with ''momentary'' in its proper place, at least for the moment. We don't ordinarily use the columns of The Home Forum to report the personal travels of readers' families. But Marguerite Watson of Riverton, N.J., notes that our poem entitled ''Regina to Banff'' appeared at the same time that her husband's brother's daughter Regina decided to move to Banff. Bon voyage!

The variations on ''going like 60'' in the fall's cliches competition suggested that most readers, like us, thought of it in terms of driving a car. But friend John Gould writes that people were going like 60 a good 50 years before any automobile did it. They were farmers using a cream separator that had to be cranked at exactly 60 turns a minute or you wouldn't get the right grade of cream. Please pass the non-dairy whipping product.
