A representative mid-nineteenth-century traditionalist was being asked to judge the work of a "wholly new" order of craftsman. His reply to the first letter (implied by her second letter to him – his letters do not survive) must have told her that the "Alabaster" poem lacked form, that it was imperfectly rhymed and its metric beat spasmodic, a judgment which would have been shared at the time by most of the fraternity of literary appraisers. The unorthodoxy of melodic pattern controlled by key words, wherein the parts express whole, the altering of metric beat to slow or speed the nature of time itself (the theme of the "Alabaster" poem), give it dimensions which he was not equipped to estimate. He was trying to measure a cube by the rules of plane geometry.
