As though the new spring-life were too plentiful to find room in the frogs and toads already existing, it calls for more frogs and toads; and new creatures are born to share the extra vitality. Like the flowers and the fish, the frogs, too, give forth new life. Within them, too, the miracle is performed. The tiny eggs of the one wake up and begin to grow. The tiny living bodies in the fertilizing principle of the other also wake up and begin to grow. But higher life is better guarded, because less prolific. The frog and the toad lay but few eggs as compared with the fish. Fish eggs may drop under the stones or float away, and so escape the vital touch of the fertilizing principle. There are so many that numbers may be lost and yet enough remain to continue the family. Not so with the frog family. No egg may be lost. So we find that the eggs of the frog are not dropped singly, like so many shot, but are bound together by a colorless, transparent, jelly-like substance, much like that found in the morning-glory seed, and which like that supplies nourishment to the young life, for the tadpole feeds upon it until he is able to seek other food. Moreover, instinct has taught the frog the need of extreme caution in the act of fertilization. Every egg _must_ be fertilized. As the time draws near for the dropping of the few eggs into the water, the male frog so places himself that the moment the eggs are being laid, he pours over them, one by one, as they fall into the water, the fertilizing fluid.
From what we have just learned of the animals and plants living in Europe during this age, we can frame some conception of the different climatic conditions of Europe. On the one hand, we have a country with a mild and genial climate. Trees of a warm latitude were then growing as far north as Paris, and we may well suppose Europe to have abounded in shady forests and grassy plains, through which flowed large rivers. It was just such a country as that in which elephants and southern animals would flourish, while vast herds of deer and bovine animals wandered over the entire length and breadth of the land. Where animal life was so abundant there were sure to be carnivorous animals also, and lions, hyenas, tigers, and other animals added to the variety of animal life.
It was rather interesting to note that the formation of the right bank was exactly the same as that of the Paredao Grande we had seen in Matto Grosso. Vertical sides in great rectangles were noticeable, intersected by passages--regular canons--where small huts could be seen at the foot of the picturesque rocks, especially at places where small streamlets entered the Tapajoz. I was told that little lakes had formed beyond those frontal rocky masses, the entrances to which were blocked at low water by sand-bars. Beyond that row of vertical red rocks was a more or less confused mass of hills, some dome-like, others of a more elongated form, but still with a well-rounded sky-line. The water of the stream had now changed colour altogether, and had become of a deep green. Islets could be seen far, far away to the left side of the river, mere white dots and lines along the water-line, most of them having white sand-beaches around them; while on the right bank the great red walls in sections continued for many miles. As we neared the mouth of the Tapajoz, the river had the immense width of 14 kil. On the right, after going through the Passagem dos Surucue, we passed the mountain of Jaguarary, which stood prominent along a flat elevation on the right bank.
