Thus talking, we pushed on until we came to a pleasant grove which stretched down to the water's edge. Here, we halted to rest, seating ourselves under a large tree, by a rivulet that murmured and splashed along its pebbly bed into the great ocean before us. A thousand gaily-plumaged birds flew twittering above us, and Fritz and I gazed up at them.

My son suddenly started up.

"A monkey," he exclaimed. “I am nearly sure I saw a monkey."

As he spoke, he sprang round to the other side of the tree, and in doing so, stumbled over a small round object. He handed it to me, remarking as he did so that it was a round bird's nest, of which he had often heard. "You may have done so," said I, laughing, "but this is a coconut."

We split open the nut, but, to our disgust, found the kernel dry and uneatable.

"Hullo," cried Fritz, "I always thought a coconut was full of delicious sweet liquid, like almond milk."

"So it is," I replied, "when young and fresh, but as it ripens the milk becomes congealed, and in course of time is solidified into a kernel. This kernel then dries as you see here, but when the nut falls on favorable soil, the germ within the kernel swells until it bursts through the shell, and, taking root, springs up a new tree."

"I do not understand," said Fritz, "how the little germ manages to get through this great thick shell, which is not like an almond or hazelnut shell, which is divided down the middle already."

"Nature provides for all things," I answered, taking up the pieces. " Look here, do you see these three round holes near the stalk? It is through them that the germ obtains egress. Now let us find a good nut if we can."

As coconuts must be overripe before they fall naturally from the tree, it was not without difficulty that we obtained one in which the kernel was not dried up. When we succeeded, however, we were so refreshed by the fruit that we could defer eating until later in the day, and so spare our stock of provisions.

Adapted from Volume Four of The Natural History of Animals: The Animal Life of the World in Its Various Aspects and Relations by James Richard Ainsworth Davis (1903)

The examples of protective resemblance so far quoted are mostly permanent adaptations to one particular sort of surrounding. There are, however, numerous animals which possess the power of adjusting their color more or less rapidly so as to harmonize with a changing environment.

Some of the best known of these cases are found among those mammals and birds that inhabit countries more or less covered with snow during a part of the year. A good instance is afforded by the Irish or variable hare, which is chiefly found in Ireland and Scotland. In summer, this looks very much like an ordinary hare, though rather grayer in tint and smaller in size, but in winter it becomes white with the exception of the black tips to the ears. Investigations that have been made on the closely allied American hare seem to show that the phenomenon is due to the growth of new hairs of white hue.

The common stoat is subject to similar color change in the northern parts of its range. In summer it is of a bright reddish brown color with the exception of the under parts, which are yellowish white, and the end of the tail, which is black. But in winter, the entire coat, save only the tip of the tail, becomes white, and in that condition the animal is known as an ermine. A similar example is afforded by the weasel. The seasonal change in the vegetarian Irish hare is purely of protective character, but in such an actively carnivorous creature as a stoat or weasel, it is aggressive as well, rendering the animal inconspicuous to its prey.

A stoat might also be called __________.

The orangutan is found only in Sumatra and Borneo, and is common in either of these islands—in both of which it occurs always in low, flat plains, never in the mountains. It loves the densest and most sombre of the forests, which extend from the seashore inland, and thus is found only in the eastern half of Sumatra, where alone such forests occur, though, occasionally, it strays over to the western side. On the other hand, it is generally distributed through Borneo, except in the mountains, or where the population is dense. In favorable places the hunter may, by good fortune, see three or four in a day.

Except in the pairing time, the old males usually live by themselves. The old females and the immature males, on the other hand, are often met with in twos and threes, and the former occasionally have young with them, though the pregnant females usually separate themselves, and sometimes remain apart after they have given birth to their offspring. The young orangs seem to remain unusually long under their mother’s protection, probably in consequence of their slow growth. While climbing, the mother always carries her young against her bosom, the young holding on by the mother’s hair. At what time of life the orangutan becomes capable of propagation, and how long the females go with young is unknown, but it is probable that they are not adult until they arrive at ten or fifteen years of age. A female which lived for five years at Batavia had not attained one-third the height of the wild females. It is probable that, after reaching adult years, they go on growing, though slowly, and that they live to forty or fifty years. The Dyaks tell of old orangs that have not only lost all their teeth, but which find it so troublesome to climb that they maintain themselves on windfalls and juicy herbage.

The “Dyaks” are most probably __________.

Adapted from The Fight at the Pass of Thermopylæ by Charlotte M. Yonge (1876)

The troops sent for this purpose were from different cities, and amounted to about 4,000 who were to keep the pass against two millions. The leader of them was Leonidas, who had newly become one of the two kings of Sparta, the city that above all in Greece trained its sons to be hardy soldiers, dreading death infinitely less than shame. Leonidas had already made up his mind that the expedition would probably be his death, perhaps because a prophecy had been given at the Temple at Delphi that Sparta should be saved by the death of one of her kings of the race of Hercules. He was allowed by law to take with him 300 men, and these he chose most carefully, not merely for their strength and valor, but selecting those who had sons, so that no family might be altogether destroyed. These Spartans, with their helots or slaves, made up his own share of the numbers, but all the army was under his generalship. It is even said that the 300 celebrated their own funeral rites before they set out lest they should be deprived of them by the enemy, since, as we have already seen, it was the Greek belief that the spirits of the dead found no rest till their obsequies had been performed. Such preparations did not daunt the spirits of Leonidas and his men, and his wife, Gorgo, not a woman to be faint-hearted or hold him back. Long before, when she was a very little girl, a word of hers had saved her father from listening to a traitorous message from the King of Persia; and every Spartan lady was bred up to be able to say to those she best loved that they must come home from battle "with the shield or carried upon it."

Why did the Spartans celebrate their funeral rites before they departed?

The inhabitants of the Sandwich Islands, which lie about six thousand three hundred miles from Arica—a city in Chile, might have imagined themselves safe from any effects that could be produced by an earthquake taking place so far away from them. But on the night between August 13th and 14th, the sea around this island group rose in a surprising manner, and many thought the islands were sinking, and would shortly subside altogether beneath the waves. Some of the smaller islands, indeed, were for a time completely submerged. Before long, however, the sea fell again, and as it did so the observers "found it impossible to resist the impression that the islands were rising bodily out of the water." For no less than three days this strange oscillation of the sea continued to be experienced, the most remarkable ebbs and floods being noticed at Honolulu, on the island of Woahoo.

But the sea-wave swept onward far beyond these islands. At Yokohama, in Japan, more than ten thousand five hundred miles from Arica, an enormous wave poured in on August 14th, but at what hour we have no satisfactory record. So far as distance is concerned, this wave affords most surprising evidence of the stupendous nature of the disturbance to which the waters of the Pacific Ocean had been subjected. The whole circumference of the earth is but twenty-five thousand miles, so that this wave had traveled over a distance considerably greater than two-fifths of the earth's circumference. A distance which the swiftest of our ships could not traverse in less than six or seven weeks had been swept over by this enormous undulation in the course of a few hours.

The penguins are a group of birds inhabiting the southern ocean, for the most part passing their lives in the icy waters of the Antarctic seas. Like the ratitae, penguins have lost the power of flight, but the wings are modified into swimming organs and the birds lead an aquatic existence and are scarcely seen on land except in the breeding season. They are curious-looking creatures that appear to have no legs, as the limbs are encased in the skin of the body and the large flat feet are set so far back that the birds waddle along on land in an upright position in a very ridiculous manner, carrying their long narrow flippers held out as if they were arms. When swimming, penguins use their wings as paddles while the feet are used for steering.

Penguins are usually gregarious—in the sea, they swim together in schools, and on land, assemble in great numbers in their rookeries. They are very methodical in their ways, and on leaving the water, the birds always follow well-defined tracks leading to the rookeries, marching with much solemnity one behind the other in soldierly order.

The largest species of penguins are the king penguin and the emperor penguin, the former being found in Kerguelen Land, the Falklands, and other southern islands, and the latter in Victoria Land and on the pack ice of the Antarctic seas. As they are unaccustomed from the isolation of their haunts to being hunted and persecuted by man, emperor penguins are remarkably fearless, and Antarctic explorers invading their territory have found themselves objects of curiosity rather than fear to the strange birds who followed them about as if they were much astonished at their appearance.

The emperor penguin lays but a single egg and breeds during the intense cold and darkness of the Antarctic winter. To prevent contact with the frozen snow, the bird places its egg upon its flat webbed feet and crouches down upon it so that it is well covered with the feathers. In spite of this precaution, many eggs do not hatch and the mortality amongst the young chicks is very great.

"The Modern Day vs. the 'Good 'Ol Days'" by Daniel Morrison (2014)

You may have, at one time or another, in your life, heard an elderly person bemoan the violence of our times and express a yearning for the “good ol’ days” of his or her youth. We might reasonably wonder what bygone era would be better than these days we live in. The days when children were considered lucky to make it past their fifth birthday? The days when the entire planet convulsed to the imperial and militaristic urges of the European powers? The days when the specter of nuclear war hung over every man, woman, and child?

The truth of the matter is we live in the most relatively peaceful time period in human history. Death by infectious disease is no longer the norm for everyone; the survival rate for children continues to grow around the world; and conflict, the type which involves and threatens the civilian population, is now the exception rather than the rule. Of course, none of these things have been eradicated from our society. Such a complete elimination of disease, violence, and death may never be possible. But, statistics from human history track one almost entirely uninterrupted progression—from almost everyone dying a violent or disease-ridden death to a small and unfortunate minority. Next time you hear someone claim a desire to return to the exalted days of their youth, kindly advise them to stop their misguided nostalgia and start contributing to the onward march of humanity.
