The second day we marched about ten miles to the foot of the cliffs. Passed through dense forests close to the base of the cliffs. Saw manlike creatures and a low order of ape in one band, and some of the men swore that there was a white man among them. They were inclined to attack us at first; but a volley from our rifles caused them to change their minds. We scaled the cliffs as far as we could; but near the top they are absolutely perpendicular without any sufficient cleft or protuberance to give hand or foot-hold. All were disappointed, for we hungered for a view of the ocean and the outside world. We even had a hope that we might see and attract the attention of a passing ship. Our exploration has determined one thing which will probably be of little value to us and never heard of beyond Caprona’s walls—this crater was once entirely filled with water. Indisputable evidence of this is on the face of the cliffs. Our return journey occupied two days and was as filled with adventure as usual. We are all becoming accustomed to adventure. It is beginning to pall on us. We suffered no casualties and there was no illness. I had to smile as I read Bradley’s report. In those four days he had doubtless passed through more adventures than an African big-game hunter experiences in a lifetime, and yet he covered it all in a few lines. Yes, we are becoming accustomed to adventure. Not a day passes that one or more of us does not face death at least once. Ahm taught us a few things that have proved profitable and saved us much ammunition, which it is useless to expend except for food or in the last recourse of self-preservation. Now when we are attacked by large flying reptiles we run beneath spreading trees; when land carnivora threaten us, we climb into trees, and we have learned not to fire at any of the dinosaurs unless we can keep out of their reach for at least two minutes after hitting them in the brain or spine, or five minutes after puncturing their hearts—it takes them so long to die. To hit them elsewhere is worse than useless, for they do not seem to notice it, and we had discovered that such shots do not kill or even disable them.
