[Note 12: _A solitary, spectacled stone-breaker_. To the pedestrian or
cyclist, no difference between Europe and America is more striking
than the comparative excellence of the country roads. The roads in
Europe, even in lonely and remote districts, where one may travel for
hours without seeing a house, are usually in perfect condition, hard,
white and absolutely smooth. The slightest defect or abrasion is
immediately repaired by one of these stone-breakers Stevenson
mentions, a solitary individual, his eyes concealed behind large green
goggles, to protect them from the glare and the flying bits of stone.]

[Note 13: _Ashamed and cold_. An excellent example of what Ruskin
called "the pathetic fallacy."]

[Note 14: _The foliage is coloured like foliage in a gale_. Cf.
Tennyson, _In Memoriam_, LXXII:--

"With blasts that blow the poplar white."]

[Note 15: _Wordsworth, in a beautiful passage_. The passage Stevenson
quotes is in Book VII of _The Prelude_, called _Residence in London_.]

[Note 16: _Cologne Cathedral, the great unfinished marvel by the
Rhine_. This great cathedral, generally regarded as the most perfect
Gothic church in the world, was begun in 1248, and was not completed
until 1880, seven years after Stevenson wrote this essay.]

[Note 17: _In a golden zone like Apollo's._ The Greek God Apollo,
later identified with Helios, the Sun-god. The twin towers of Cologne
Cathedral are over 500 feet high, so that the experience described
here is quite possible.]
