03-A. The Atlantic Ocean

The Atlantic Ocean is one of the oceans that separate the Old World from the New. For centuries it kept the Americas from being discovered by the people of Europe.

Many wrong ideas about the Atlantic made early sailors unwilling to sail far out into it. One idea was that it reached out to "the edge of the world." Sailors were afraid that they might sail right off the earth. Another idea was that at the equator the ocean would be boiling hot.

The Atlantic Ocean is only half as big as the Pacific, but it is still very large. It is more than 4,000 miles (6,000 km) wide where Columbus crossed it. Even at its narrowest it is about 2, 000 miles (3,200 km) wide. This narrowest place is between the bulge of south America and the bulge of Africa.

Two things make the Atlantic Ocean rather unusual. For so large an ocean it has very few islands. Also, it is the world's saltiest ocean.

There is so much water in the Atlantic that it is hard to imagine how much there is. But suppose no more rain fell into it and no more water was brought to it by rivers. It would take the ocean about 4,000 years to dry up. On the average the water is a little more than two miles (3.2 km) deep, but in places it is much deeper. The deepest spot is near Puerto Rico. This "deep" 30, 246 feet - almost six miles (9.6 km).

One of the longest mountain ranges of the world rises the floor of the Atlantic. This mountain range runs north and south down the middle of the ocean. The tops of a few of the mountains reach up above the sea and make islands. The Azores are the tops of peaks in the mid-Atlantic mountain range. Several hundred miles eastward from Florida there is a part of the ocean called the Sargasso Sea. Here the water is quiet, for there is little wind. In the days of sailing vessels the crew were afraid they would be becalmed here. Sometimes they were.

Ocean currents are sometime called "rivers in the sea." One of these "river" in the Atlantic is called the Gulf Stream. It is a current of warm water. Another is the Labrador Current - cold water coming down from the Arctic. Ocean currents affect the climates of the lands near which they flow. The Atlantic furnishes much food for the people on its shores. One of its most famous fishing regions, the Grand Banks, is near Newfoundland.






Today the Atlantic is a great highway. It is not, however, always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the Far North across the paths of ships.

We now have such fast ways of traveling that this big ocean seems to have grown smaller. Columbus sailed for more than two months to cross it. A fast modern steamship can make the trip in less than four days. Airplanes fly from New York to London in only eight hours and from South America to Africa in four!

09-A. Learned words and popular words

In every cultivated language there are two great classes of words which, taken together, make up the whole vocabulary. First, there are those words with which we become familiar in ordinary conversation, which we learn, that is to say, from the members of our own family and from our friends, and which we should know and use even if we could not read or write. They concern the common things of life, and are the stock in trade of all who speak the language. Such words may be called “popular,” since they belong to the people at large and are not the possession of limited class only.

On the other hand, our language includes a large number of words which are relatively seldom used in ordinary conversation. Their meanings are known to every educated person, but there is little occasion to use them at home. Our first acquaintance with them comes not from our mother's lips or from the talk of our classmates, but from books that we read, lectures that we hear, or the more formal conversation of highly educated speakers who are discussing some particular topic in an elevated style. Such words are called "learned", and the difference between them and "popular" words is of great importance to a right understanding of language.

The difference between popular and learned words may be easily seen in a few examples. We may describe a girl as “lively” or as "vivacious." In the first case, we are using a native English word formed from the familiar noun life. In the latter, we are using a Latin derivative which has exactly the same






meaning. Yet the atmosphere of the two words is quite different. No one ever got the adjective lively out of a book. It is a part of everybody's vocabulary. We cannot remember a time when we did not know it, and we feel sure that we learned it long before we were able to read. On the other hand, we must have passed several years of our lives before learning the word vivacious. We may even remember the first time that we saw it in print or heard it from some grown-up friend. Both lively and vivacious are good English words, but Lively is popular and vivacious is learned.

The terms "popular" and "learned,” as applied to words, are not absolute definitions. No two persons have the same stock of words, and the same word may be "popular" in one man's vocabulary and "learned in another's. There are also different grades of "popularity." Still, the classification into "learned" and "popular" is convenient and sound. Different opinions may come up as to the classification of any particular word, but there can be no difference of opinion about the general principle. We must be careful, however, to avoid misconception. When we call a word "popular," we do not mean that it is a favorite word, but simply that it belongs to the people as a whole that is, it is everybody's word, not the possession of a limited number. When we call a word "learned” we do not mean that it is used by learned persons alone, but simply that its presence in the English vocabulary is due to books and the cultivation of literature rather than to the actual needs of ordinary conversation.
