Third Awake, 4 Juli 2207
Another sleep has come and our tiredness is greater. Doctor Dorn thinks we are about twenty-five miles from Lost City.
After an hour of the walk, we turned off one of the lamps, leaving only three on, and the blackness of the passage seemed to jump in toward us. It is like a live and evil thing, the blackness, running in fear from the light before us, yet following so closely behind. Sometimes I cannot help feeling that, like the Groles, it is just waiting for our last lamp to go out so it can rush in and kill us. In one thing we have been fortunate. Even with only three lamps lighted no one has had the Black Fear. But after this sleep we will burn only two lamps and again the blackness will move closer. It is not a pleasant thought to sleep with.
Fourth Awake, 5 Juli 2207
Except for the greater darkness because of only two lamps, all is the same. It is strange not to have the City Signals to tell us when to sleep and when to awake. Because we have only our tiredness to measure awakes and sleeps, I am no longer sure the date I write above is the right one.
We do not talk as much now. All of our strength must be used for walking.
Fifth Awake, 6 Juli 2207
One of the lamps went out while we were walking, this awake. Although we were able to light it again in a few seconds, we could not help thinking how the Groles might have come if the other lamp hadn't been burning.
