P.S.--I may add that, with respect to these words "happy low lie down,"
from my habit of looking for solutions of difficulties in parallels and
antitheses, I have arrived at a different conclusion from any that has yet
been suggested. Finding "uneasy" used _adverbially_ in the last line, I see
no reason why "happy" should not also be taken _adverbially_ in the
preceding line: we should then have the same verb, "lie" and "lies,"
repeated antithetically in the same mood and tense.
The article _the_ before "low" has probably been omitted in the press, and
may be either actually restored or elliptically understood:
"Then _happy_ [the] low lie down;
_Uneasy_ lies the head that wears a crown."
