[Note 18: _The two hall-fires at night_. In mediaeval castles, the
hall was the general living-room, used regularly for meals, for
assemblies, and for all social requirements. The modern word
"dining-hall" preserves the old significance of the word. The familiar
expression, "bower and hall," is simply, in plain prose, bedroom and
sitting-room.]

[Note 19: _Association is turned against itself_. It is seldom that
Stevenson uses an expression that is not instantly transparently
clear. Exactly what does he mean by this phrase?]

[Note 20: "_As from an enemy_." Alluding to the passage Stevenson has
quoted above, from Wordsworth's _Prelude_.]

[Note 21: _Our noisy years did indeed seem moments_. A favorite
reflection of Stevenson's, occurring in nearly all his serious
essays.]

[Note 22: _Shelley speaks of the sea as "hungering for calm."_ This
passage occurs in the poem _Prometheus Unbound_, Act III, end of Scene
2.

"Behold the Nereids under the green sea--
Their wavering limbs borne on the wind like stream,
Their white arms lifted o'er their streaming hair,
With garlands pied and starry sea-flower crowns,--
Hastening to grace their mighty Sister's joy.
It is the unpastured sea hungering for calm."]
