Not many minutes passed before Mr. Allis reached home. He had seen the fire at a distance, and, understanding the danger far better than his wife, hurried home as rapidly as possible.

Poor Annie and Susie were sadly frightened. When they saw the smoke and fire so near the house and stacks of grain, they cried as if their little hearts would break; but there was no one to hear them, for their mother could not be spared a moment until the danger was past. Poor children! They soon had enough of prairie-fires, and they thought they would be very thankful if ever they could see their father and mother and Mary alive again. Sometimes they were almost suffocated by the smoke which the rising wind drove into the house, and then they thought they should surely be burned to death. Still, lonely and frightened as they were, they did not attempt to go out. They remembered that their mother had told them not on
any account
to leave the house, and, like obedient children, they did as she had told them.

It was two hours—but it seemed much longer to the poor little girls—before their mother came in; and then they scarcely knew her, for her face was blackened with smoke and dust, her hands were burned sadly, and the skirt of her dress torn and burned in many places. Although they were excited and curious, yet these good children undressed and went to bed, helping themselves all they could, that their mother might rest, and trying to wait until morning for all they wished to know.

Meanwhile, Mrs. Allis busied herself, weary as she was, in providing a comfortable supper for her husband, who had eaten nothing since dinner-time. It was past midnight when Mr. Allis and Mary came to the house, and they too were tired enough, as we may suppose.

But, above all, they were grateful to that kind heavenly Father who had so mercifully preserved and protected them from harm amid such dangers. Little did any of them sleep that night; and it was not strange that the morning, which came on wet and showery, found them but little refreshed after the unusual fatigue of the preceding night. But the children were awake with the first light, and eagerly asking questions about the fire.

"But what is a
back-fire?
" said Annie, when her father had finished telling them about the matter. "How do you set a back-fire?"

"Well, Annie, we light
another fire
, nearer the house or fence which we are trying to save, and then, with a brush or broom, or sometimes a little stick,
whip it out
, so that it cannot burn very fast. When the grass is burnt off in this way there is nothing left for what we call the 'prairie-fire' to burn, you see. If we can do this in season, the house or stacks are generally safe."

THE BABY

How tired every one was all day after the prairie-fire! Well would it have been if the matter had terminated in fatigue. Early in the day the feeble mother had to betake herself to her bed; and on the following morning Mr. Allis, to his great surprise, found himself rudely shaken by the ague. Not many days passed ere Mrs. Allis and Mary found themselves at the mercy of the same annoying visitor. Sometimes the three shook in concert; and then you may imagine that the little girls had enough to do to carry water to satisfy their thirst. Occasionally the chills would seem to be broken up for a few days, and then they would most unexpectedly return. Several times Mr. Allis thought himself perfectly well, and once or twice he went to the grove a number of miles distant, with his team, for a load of wood, and on the way there or back would be attacked with a chill, and it was only by a great effort that he reached home. The little girls were quite well; but they did not find their prairie home as pleasant in the cold winter as it was in the glad summer-time. Oh, how they longed for spring! And when it came how they rejoiced over the little lambs and calves in their father's yard, and how delighted were they when the first sweet violets peeped forth! Still their joy was to be increased: a sweeter prairie-flower than any of these bloomed in their humble cabin, opening a fount of untold gladness in the hearts of all. One bright morning a sweet little sister was presented to the delighted children.
