"A great deal, when once you put yourself in the Southerner's place. We in the North are liable to emphasize only the cruelty of slavery and are often unable to understand how enlightened and Christian men could keep slaves and fight to keep them. You see there were reasons."

Mary nodded.

"Of course, as I said before, all the cotton-raising in the world could not make the thing right. It was wrong from start to finish. Nevertheless it does explain why some of our people felt the freeing of the slaves so unjust and such a blow to their prosperity that they threatened secession from the Union."

"And it was because Abraham Lincoln would not allow them to secede that the war was fought!" announced Carl triumphantly.

"Precisely! You cannot allow part of a country to rise up and walk out any more than you can let some of the wheels of a watch announce they are not going to turn any more," laughed his uncle. "It requires every part to make the watch go; and it takes the united strength of a people to make a nation. North and South were all beloved children of one land, and Abraham Lincoln, like the father of a big family, was not going to let any of the household break away from the organization to which it belonged. It meant a struggle to do the two things necessary—free the slaves and preserve the Union; but quarrels are sometimes necessary in families. After they are over there is a more perfect understanding. So it has been with this one. Both sides paid a fearful price but as a result we now have one nation, indivisible, with liberty and justice for all."

"That's the oath of allegiance!" cried Carl, Mary, and Tim in chorus, as they leaped to their feet and stood at salute.

"We say it at school every morning," continued Tim, "but I never knew before what it meant."

"You will know better now, won't you?" Captain Dillingham replied. "Every time you say those words remember the brave men of the South who really believed they had a right to establish a government of their own and protect the prosperity of their part of this great land. If you do this you will learn to honor both sides alike, each of which fought so devotedly for the cause he cherished. And now that the war is over the entire country has the South to thank for one of its greatest sources of wealth—cotton. The South raises it; the North, with its many mills, transforms the raw product into a finished commodity. How is that for team work? Could there be better proof of how vitally each section needs the other?"
