"A western emigrant train. The occupation of the west. With every year the line of settlements was pushed farther westward. Along the great highways, and by trails across the prairies, one might see long emigrant trains. Covered wagons contained the family goods and carried the women and children; the men marched behind or rode on horseback; they drove the sheep and cattle which they were taking to the new homes. These emigrants often formed large parties for better protection against Indians and wild beasts. They camped at night by streams of water when they could. They built their camp fires and kept guard all night, for they could hear the howling of wolves and sometimes see Indians stealing toward them. As they moved on, they would meet men and wagons coming from the opposite direction. Already the great West was sending back produce and droves of cattle and pigs to the Eastern markets."—Scudder, 1897

"Laying the Atlantic Cable. In 1866, a previous attempt in 1858 having failed, a telegraphic cable was laid upon the bed of the Atlantic between America and Europe. This cable was followed by others; but a closer connection between the United States and the Old World than any effected by the telegraph is formed by the constant passage back and forth of people. With the close of the war, immigration, which had suffered a check, increased rapidly. From 1871 to 1880 nearly three millions, and from 1881 to 1890, more than five millions, of people migrated to the United States. During the present decade, up to 1897, three millions of immigrants have swelled the population of the century. From 1789 to 1894, a period of one hundred and five years, the United States has absorbed an alien population of about eighteen millions."&mdash;Scudder, 1897

W. of Asia, and some parts of India, and of which the cultivation is no less wide, and still extending. Some parts of China produce large crops. The stem, which is straight and simple, reaches a height of 30 to 60 feet, and bears a head of 40 to 80 glaucous pinnated leaves, 8 to 10 feet long, and a number of branching spadices, each of which on the female tree bears 180 to 200 fruits. A bunch of dates weighs 20 or 25 pounds, so that an average year's crop may be reckoned at 300 to 600 pounds per tree, and the yield per acre at about 12 times that of corn. This is one of the most important and useful of all the palms.

"Hedgehog is a quadruped distinguished by having the body covered with spines instead of hair. The skin of the back is provided with a great orbicular muscle which enables the animal to roll itself up in the form of a ball. The tail is very short. There are several species&mdash;some authorities enumerate 14. The best known is the common hedgehog. This species has a long nose, the nostrils bordered on each side by a loose flap; the hind feet have five toes; the ears are short, rounded, naked and dusky; the upper part of the face, sides, and rump covered with strong, coarse hair, of a yellowish ash color, the back with sharp strong spines of a whitish tint with a bar of black through their middle. They are usually abot 10 inches long, the tail about one. Their usual residence is in small thickets, and they feed on fallen fruits, roots, and insects; they are also fond of flesh, either raw or roasted. The hedgehog defends himself from the attacks of other animals by rolling himself up, and thus exposing no part of his body that is not furnished with a defense of spines. It may be rendered domestic to a certain degree, and has been employed to destroy cockroaches which it pursues with avidity. In the winter the hedgehog wraps itself in a warm nest, composed of moss, dried hay and leaves, and remains torpid till spring."—(Charles Leonard-Stuart, 1911)

"The Umbrella Bird is a native of Peru. It is about the size of a crow, with deep black plumage; the head is adorned with a large spreading crest, which arises from a contractile skin, and capable of being erected at will; the shafts of the crest-feathers are white, and the plumes glossy blue, hair-like and curved outward at the tips. When the crest is laid back the shafts form a compact white mass, sloping up from the back of the head; when it is erected the shafts radiate on all sides from the top of the head, reaching in front beyond and below the beak, which is thus completely concealed from view. A long cylindrical plume hangs down from the middle of the neck; the feathers of the plume lap over each other like scales, and are bordered with metallic blue. Umbrella birds associate in small flocks, and live almost entirely upon fruits. Their cry, which resembles the lowing of a cow, is most frequently heard just before sunrise and after sunset."&mdash;(Charles Leonard-Stuart, 1911)

In Cyclops the body is more distinctly segmented and the shell is not bivalve; the head bears antenn&aelig;, mandibles, and maxill&aelig;, and the first five segments of the thorax bear swimming appendages. Water fleas fed on microscopic plants and animals and on organic debris, while they themselves&ndash; often occurring in countless swarms&ndash; form an important part of the food supply of certain fishes."&mdash;(Charles Leonard-Stuart, 1911)

"Water Flea is a popular name for minute aquatic Crustaceans such as daphnia, cypris, and cyclops. In Cypris also the shell is bivalve; there are five pairs of appendages on the head and two on the body; most of these are used in swimming or creeping. Among cyprids parthenogenesis again occurs, and in some species males have never been observed, while parthenogenetic development has been traced for as many as 40 successive generations. The females bear large egg sacs. Water fleas fed on microscopic plants and animals and on organic debris, while they themselves&ndash; often occurring in countless swarms&ndash; form an important part of the food supply of certain fishes."&mdash;(Charles Leonard-Stuart, 1911)

"Water Flea is a popular name for minute aquatic Crustaceans such as daphnia, cypris, and cyclops. The common Daphnia pulex, abundant in fresh water, is a good representative. The body is enclosed in a bivalve shell; there is a large single eye; a pair of large antenn&aelig; are used as swimming organs. The daphnids are marvellously prolific, and for prolonged periods parthenogenetic. There is an interesting difference between the winter eggs which require fertilization and the summer eggs which do not. The females have a dorsal brood chamber betwen the shell and the back. Water fleas fed on microscopic plants and animals and on organic debris, while they themselves&ndash; often occurring in countless swarms&ndash; form an important part of the food supply of certain fishes."&mdash;(Charles Leonard-Stuart, 1911)

"Water Beetles are beetles which live on or in the water. The Dytiscus, common in stagnant water, is olive-green above, and oval in shape. The respiratory organs of the perfect insect are not adapted to obaining air from the water; it comes occasionally to the surface of the water for air, where it lies on its back, the openings of its air tubes in the last segment of the abdomen, being exposed."&mdash;(Charles Leonard-Stuart, 1911)

"Whale is a name that may be taken as equivalent to Cetacean, and applied to any member of that order of mammals, which inculdes two great sets: the toothed whales, such as sperm whale and dolphin, and the whale-bone whales, such as right whale and rorqual, in which the teeth are only embryonic. The order Cetacea is usually divided into three sub-orders: (1) the Mystacoceti or Bal&aelig;noidea, baleen or whalebone whales; (2) the Odontoceti or Delphinoidea, toothed whales; and (3) the Arch&aelig;oceti or extinct Zeuglodonts. The differences between the extant sub-orders are so great that any idea of the close relationship must be abandoned; their common ancestry must be far back, and indeed it is doubtful whether our classification might not be brought nearer the truth by recognizing two distinct orders. Less specialized than the modern types are the extinct Zeuglododonts of the Eocene period, but it is by no means certain that they should be included within the order Cetacea."&mdash;(Charles Leonard-Stuart, 1911)

"Wigeon is one of the most popular birds with the American sportsman. Length about eighteen inches; the male has the forehead and top of head white, cheeks and hinged part of the neck reddish-chestnut, upper parts grayish-white, irregularly zigzagged with black, wing coverts white tipped with black, primaries dark brown, speculum green, edged with black; throat rufous, breast and belly white; the female has sober plumage of various shades of brown. The wigeon is one of the commonest ducks of the extreme N. of Europe, frequenting grassy swamps, lakes, and rivers, and feeding in the daytime, chiefly on aquatic vegetation. The American wigeon is larger than the European or common wigeon, and has the upper parts finely waved transversely with black and reddish-brown, top of head and under parts white. It breeds chiefly in the N. parts of America and is common in winter on the coasts of the United States and in the rice fields. The flesh of both species is esteemed for the table, and they are hunted both for food and for sport."&mdash;(Charles Leonard-Stuart, 1911)
