One could read easily at one o'clock.
Twilight and dawn joined hands.

The sun rose far up in the north-east.
Queer nights these! Until we got used to it, or rather until fatigue conquered us, we had no little difficulty in going to sleep.

We were not accustomed to naps in the daytime.

As a sort of compromise, I recollect that we used to spread an old sail over the skylight, and hang up blankets over the bull's-eyes in the stern, to keep out this everlasting daylight.

We needed night.
