Harry then went up to the spot, and after examining it some time, told Tommy that he believed he had found out the reason of their misfortune. "What is it?" said Tommy. "Why," said Harry, "it is only because we did not drive these stakes, which are to bear the whole weight of our house, far enough into the ground; and, therefore, when the wind blew against the flat side of it with so much violence, it could not resist. And now I remember to have seen the workman, when they begin a building, dig a considerable way into the ground to lay the foundation fast; and I should think that, if we drove these stakes a great way into the ground, it would produce the same effect, and we should have nothing to fear from any future storms." Mr Barlow then came into the garden, and the two boys showed him their misfortune, and asked him whether he did not think that driving the stakes further in would prevent such an accident for the future. Mr Barlow told them he thought it would; and that, as they were too short to reach to the top of the stakes, he would assist them. He then went and brought a wooden mallet, with which he struck the tops of the stakes, and drove them so fast into the ground that there was no longer any danger of their being shaken by the weather. Harry and Tommy then applied themselves with so much assiduity to their work that they in a very short time had repaired all the damage, and advanced it as far as it had been before. The next thing that was necessary to be done, was putting on a roof, for hitherto they had constructed nothing but the walls. For this purpose they took several long poles, which they had laid across their building where it was most narrow, and upon these they placed straw in considerable quantities, so that they now imagined they had constructed a house that would completely screen them from the weather. But in this, unfortunately, they were again mistaken; for a very violent shower of rain coming just as they had finished their building, they took shelter under it, and remarked for some time, with infinite pleasure, how dry and comfortable it kept them; but at last the straw that covered it being completely soaked through, and the water having no vent to run off, by reason of the flatness of the roof, the rain began to penetrate in considerable quantities.
