REUBEN BROWER, who wrote many books, died in 1975. In an interview, Robert Frost said, "I remember Brower one day in somebody else's class when he was a student at Amherst - Reuben Brower, afterwards the Master of Adams House at Harvard. I remember I said, `Anyone want to read that poem to me?' It was `In going to my naked bed as one that would have slept,' Edwards's old poem. He read it so well I said, `I give you A for life."'
