But they are in The Blue Estaminet.
"Weary I am of worrying and warning;
For all my toil I get it in the neck;
I am fed up with it; and from this morning
I shall not seek to keep your crimes in check;
Sin as you will—I shall but acquiesce;
Sleep on, O sentinels—I shall not curse;
And so, maybe, from sheer contrariness
Some day a guard may be a slight success;
At any rate you cannot well do worse."
