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 theme is the main theme of this excerpt from the metal pig by hans christian andersen? in the garden of the grand duke's palace under the roof of one of the wings were a thousand roses bloom in winter, a little ragged boy had been sitting the whole day long. the boy might serve as a type of italy lovely and smiling and yet suffering. he was hungry and thirsty but no one gave him anything and when it became dark and they were about to close the gardens, the porter turned him out. a long time he stood musing on the bridge which crosses the arno and looking at the glittering stars that were reflected in the water which flowed between him and the wonderful marble bridge trinita. he then walked away towards the metal pig, half note down, clasped it with his arms, and, putting his mouth to the shining snout, drink deep droughts of the fresh water. close-by lay a few salad leaves into chestnuts, which register for his supper. no one was in the street but himself. it belonged only to him. he boldly seated himself on the pig's back, leaned forward so that his curly head could rest on the head of the animal, and, before he was aware, fell asleep. it was midnight. the metal pig raised himself gently, and the boy heard him say quite distinctly, hold tight little boy, for i am going to run, and way he started for most wonderful ride first they arrived at the p as the del granduca and the metal horse which bears the dukes statue made allowed
