There may be dead ground in between; and I may not have got The knack of judging a distance; I will only venture A guess that perhaps between me and the apparent lovers, (Who, incidentally, appear by now to have finished,) At seven o'clock from the houses, is roughly a distance Of about one year and a half.

Le temps vole et m'emporte malgre¤   moi; j'ai beau vouloir le retenir, c'est lui qui m'entra|"ne; et cette pense¤  e me fait grande peur: vous devinez a'   peu pre'  s pourquoi. Time flies and takes me with it despite my efforts; I'd like to hold it back, but it keeps dragging me along and this thought frightens me greatly: you can perhaps guess why.
