But Goodyear kept on trying. He thought that he was just going to find out. Years went by, and still he kept on trying.

One day he was mixing some rubber with sulphur. It slipped out of his hand. It fell on the hot stove. But it did not melt. Goodyear was happy at last. That night it was cold. Goodyear took the burned piece of rubber out of doors, and nailed it to the kitchen door. When morning came, he went and got it. It had not frozen.

He was now sure that he was on the right track. But he had to find out how to mix and heat his rubber and sulphur. He was too poor to buy rubber to try with. n.o.body would lend him any more money. His family had to live by the help of his friends. He had already sold almost everything that he had. Now he had to sell his children's school-books to get money to buy rubber with.

At last his rubber goods were made and sold. Poor men who had to stand in the rain could now keep themselves dry. People could walk in the wet with dry feet. A great many people are alive who would have died if they had not been kept dry by India rubber.

You may count up, if you can, how many useful things are made of rubber. We owe them all to one man. People laughed at Goodyear once.

But at last they praised him. To be "The India-rubber man" was something to be proud of.

DOCTOR KANE IN THE FROZEN SEA.

[Ill.u.s.tration]

Kane was a doctor in one of the war ships of the United States. He had sailed about the world a great deal.

When he heard that ships were to be sent into the icy seas of the north, he asked to be sent along. He went the first time as a doctor.

Then he wanted to find out more about the frozen ocean. So he went again as captain of a ship. His ship was called the "Advance."

Kane sailed into the icy seas. His ship was driven far into the ice by a fu-ri-ous storm. She was crowded by ice-bergs. At one time she was lifted clear out of the water. The ship seemed ready to fall over on her side. But the ice let her down again. Then she was squeezed till the men thought that she would be crushed like an egg sh.e.l.l At last the storm stopped. Then came the awful cold. The ship was frozen into the ice. The ice never let go of her. She was farther north than any ship had ever been before. But she was so fast in the ice that she never could get away.

In that part of the world it is night nearly all winter. For months there was no sun at all. Daylight came again. It was now summer, but it did not get warm. Doctor Kane took sleds, and went about on the ice to see what he could see. The sleds were drawn by large dogs. But nearly all of the dogs died in the long winter night.

[Ill.u.s.tration: A Dog Sled]

Doctor Kane thought that the ice would melt. He wanted to get the ship out. But the ice did not melt at all.

At last the summer pa.s.sed away. Another awful winter came. The sun did not rise any more. It was dark for months and months. The men were ill. Some of them died. They were much dis-cour-aged. But Kane kept up his heart, and did the best he could.

At last the least little streak of light could be seen. It got a little lighter each day. But the sick men down in the cabin of the ship could not see the light.

Doctor Kane said to himself, "If my poor men could see this sunlight, it would cheer them up. It might save their lives." But they were too ill to get out where they could see the sun. It would be many days before the sun would shine into the cabin of the ship. The men might die before that time.

So Doctor Kane took some looking gla.s.ses up to the deck or top of the ship. He fixed one of these so it would catch the light of the sun.

Then he fixed another so that the first one would throw the light on this one. The last one would throw the sunlight down into the cabin where the sick men were.

One day the poor fellows were ready to give up. Then the sun fell on the looking gla.s.ses, and flashed down into the cabin. It was the first daylight the sick men had seen for months. The long winter night was over. Think how happy they were!

A DINNER ON THE ICE.

After two winters of cold and darkness, Doctor Kane made up his mind to leave the ship fast in the ice. He wanted to get to a place in Green-land where there were people living. Then he might find some way of getting home again.

The men started out, drawing the boats on sleds. Whenever they came to open water, they put the boats into the water, and took the sleds in the boats. When they came to the ice again, they had to draw out their boats, and carry them on the sleds. At first they could travel only about a mile a day.

It was a hard journey. Some of the men were ill. These had to be drawn on the sleds by the rest. They had not enough food. At one time they rested three days in a kind of cave. Here they found many birds' eggs.

These made very good food for them. At another place they staid a week. They staid just to eat the eggs of the wild birds.

After they left this place, they were hungry. The men grew thinner and thinner. It seemed that they must die for want of food. But one day they saw a large seal. He was floating on a piece of ice. The hungry men thought, "What a fine din-ner he would make for us!" If they could get the seal, they would not die of hunger.

Every one of the poor fellows trembled for fear the seal would wake up. A man named Pe-ter-sen took a gun, and got ready to shoot. The men rowed the boat toward the seal. They rowed slowly and quietly. But the seal waked up. He raised his head. The men thought that he would jump off into the water. Then they might all die for want of food.

Doctor Kane made a motion to Pe-ter-sen. That was to tell him to shoot quickly. But Peter-sen did not shoot. He was so much afraid that the seal would get away, that he could not shoot. The seal now raised himself a little more. He was getting ready to jump into the water.

Just then Petersen fired. The seal fell dead on the ice.

[Ill.u.s.tration: A Seal]

The men were wild with joy. They rowed the boats with all their might.

When they got to the seal, they dragged it farther away from the water. They were so happy, that they danced on the ice. Some of them laughed. Some were so glad, that they cried. [Ill.u.s.tration: Shooting the Seal.]

Then they took their knives and began to cut up the seal. They had no fire on the ice, and they were too hungry to think of lighting one. So they ate the meat of the seal without waiting to cook it.

DOCTOR KANE GETS OUT OF THE FROZEN SEA.

After they got the seal, Doctor Kane and his men traveled on.

Sometimes they were on the ice. Sometimes they were in the boats. The men were so weak, that they could hardly row the boats. They were so hungry, that they could not sleep well at night.

One day they were rowing, when they heard a sound. It came to them across the water. It did not sound like the cry of sea birds. It sounded like people's voices.

"Listen!" Doctor Kane said to Pe-ter-sen.

Petersen spoke the same language as the people of Greenland. He listened. The sound came again. Pe-ter-sen was so glad, that he could hardly speak. He told Kane in a half whisper, that it was the voice of some one speaking his own language. It was some Greenland men in a boat.

The next day they got to a Greenland town. Then they got into a little ship going to England. They knew that they could get home from England. But the ship stopped at another Green-land town. While they were there, a steamer was seen. It came nearer. They could see the stars and stripes flying from her mast. It was an American steamer sent to find Doctor Kane.

Doctor Kane and his men were full of joy. They pushed their little boat into the water once more. This little boat was called the "Faith." It had carried Kane and his men hundreds of miles in icy seas.

Once more the men took their oars, and rowed. This time they rowed with all their might. They held up the little flag that they had carried farther north than anybody had ever been before. They rowed straight to the steamer.

In the bow of the boat was a little man with a tattered red shirt. He could see that the captain of the boat was looking at him through a spy-gla.s.s.

The captain shouted to the little man, "Is that Doctor Kane?"

The little man in the red shirt shouted back, "Yes!"
