CHAPTER XVIII.
All day long we sped through a mountainous country whose peaks were bright with sunshine, whose hillsides were dotted with pretty villas sitting in the midst of gardens and shrubbery, and whose deep ravines were cool and shady and looked ever so inviting from where we and the birds were winging our flight through the sultry upper air.
We had plenty of chilly tunnels wherein to check our perspiration, though.

We timed one of them.

We were twenty minutes passing through it, going at the rate of thirty to thirty-five miles an hour.
Beyond Alessandria we passed the battle-field of Marengo.
Toward dusk we drew near Milan and caught glimpses of the city and the blue mountain peaks beyond.

But we were not caring for these things -- they did not interest us in the least.

We were in a fever of impatience; we were dying to see the renowned cathedral! We watched--in this direction and that--all around--everywhere.
