there is very little to indicate the further course of 'the aelfwine story ' after his sojourn in tol eressea ( as i have remarked , p. 301 , the part of the mariner is only to learn and record tales out of the past ) ; and virtually all that can be learned from these notes is found on a slip that reads : ( 29 ) how aelfwine drank of limpe but thirsted for his home , and went back to luthany ; and thirsted then unquenchably for the elves , and went back to tavrobel the old and dwelt in the house of the hundred chimneys ( where grows still the child of the child of the pine of belawryn ) and wrote the golden book .
