STORIES OF USEFUL INVENTIONS, excerpt By S. E. Forman 1911 THE MATCH There never was a time when the world was without fire, but there was a time when men did not know how to kindle fire; and after they learned how to kindle one, it was a long, long time before they learned how to kindle one easily. In these days we can kindle a fire without any trouble, because we can easily get a match; but we must remember that the match is one of the most wonderful things in the world, and that it took men thousands of years to learn how to make one. Let us learn the history of this familiar little object, the match. Fire was first given to man by nature itself. When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set ablaze by a thunderbolt, we may say that nature strikes a match. In the early history of the world, nature had to kindle all the fires, for man by his own effort was unable to produce a spark. The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by nature—by a volcano, perhaps, or by a stroke of lightning. These firebrands were carried to the home and used in kindling the fires there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would sometimes be extinguished. A sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble. In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggist had discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the match with which we are so familiar. What was the main problem with relying on nature to start a flame? Fire could only be collected with "sticks of wood" that were hard to find. Fire had to be "carefully guarded," requiring someone to stay behind from hunting. Fire had to be "carried to the home," which could be dangerous and awkward. Fire was likely hard to find, requiring a "long journey and a deal of trouble."

cookiemonster:

same story as above^ What is the main idea of the last paragraph? Early matches were dangerous and awkward. John Walker made the first match. Phosphorus was the key to the modern match. Walker's match was better than what came before.

Vocaloid:

hm

Vocaloid:

I'm a little uncertain, I don't think it's A or C since the topic sentence is about the invention of the first match.

cookiemonster:

right... sooo

Vocaloid:

B maybe? :S

cookiemonster:

hehe ok next thats what i think too :) What is the main idea of the first paragraph? It took humans a long time to develop the match. Learning how to make fire was a long struggle for humans. The world went for years without adequate fire. We often forget how the match changed the world.

Vocaloid:

"there was a time when men did not know how to kindle fire; and after they learned how to kindle one, it was a long, long time before they learned how to kindle one easily." " took men thousands of years to learn how to make one" note the emphasis on time

CHAPTER II—THE SHE-WOLF, an excerpt From White Fang By Jack London Breakfast eaten and the slim camp-outfit lashed to the sled, the men turned their backs on the cheery fire and launched out into the darkness. At once began to rise the cries that were fiercely sad—cries that called through the darkness and cold to one another and answered back. Conversation ceased. Daylight came at nine o'clock. At midday the sky to the south warmed to rose-colour, and marked where the bulge of the earth intervened between the meridian sun and the northern world. But the rose-colour swiftly faded. The grey light of day that remained lasted until three o'clock, when it, too, faded, and the pall of the Arctic night descended upon the lone and silent land. As darkness came on, the hunting-cries to right and left and rear drew closer—so close that more than once they sent surges of fear through the toiling dogs, throwing them into short-lived panics. At the conclusion of one such panic, when he and Henry had got the dogs back in the traces, Bill said: "I wisht they'd strike game somewheres, an' go away an' leave us alone." "They do get on the nerves horrible," Henry sympathized. They spoke no more until camp was made. What do the details about the length of the Arctic day add to the story? Please respond in three to five complete sentences, including specific lines from the excerpt to support your answer.

> adds imagery "south warmed to rose-colour, and marked where the bulge of the earth intervened" > gives a sense of time progression "The grey light of day that remained lasted until three o'clock" > induces a feeling of isolation/fear in the reader "it, too, faded, and the pall of the Arctic night descended upon the lone and silent land."

cookiemonster:

ok! those are the speficic lines, now can you actually like explain what the details about the length of the Arctic day add to the story?

Vocaloid:

> adds imagery "south warmed to rose-colour, and marked where the bulge of the earth intervened" > gives a sense of time progression "The grey light of day that remained lasted until three o'clock" > induces a feeling of isolation/fear in the reader "it, too, faded, and the pall of the Arctic night descended upon the lone and silent land." look before the quotes for the explanation...
