midday
But this I know . We had stuck the ends of some of the saplings into the ground in the building of our shelter , first stripping the leaves and branches from them , and when we awoke we found that many of them had thrust forth sprouts . Personally , I think that we slept at least a month ; but who may say ? The sun marked midday when we closed our eyes ; it was still in the same position when we opened them ; nor had it varied a hair 's breadth in the interim . It is most baffling , this question of elapsed time within Pellucidar . Anyhow , I was famished when we awoke . I think that it was the pangs of hunger that awoke me .
