Delicate Francis DaPavia read, from delicate onionskin, yellow pages, or pink, which he kept flipping carefully with long white fingers, the poems of bis dead chum Altman who'd eaten too much peyote in Chihuahua but read none of his own poems—a charming elegy in itself to the memory of the dead young poet, enough to draw tears from the Cervantes of Chapter Seven, and read them in a delicate Englishy voice that had me crying with inside laughter though I later got to know Francis and liked him.
