Mr Barlow had a very large garden, and an orchard full of the finest fruit-trees; and he had another piece of ground where he used to sow seeds in order to raise trees, and then they were carefully planted out in beds till they were big enough to be moved into the orchard and produce fruit. Tommy had often eaten of the fruit of the orchard, and thought it delicious, and this led him to think that it would be a great improvement to their house if he had a few trees that he might set near it, and which would shelter it from the sun and hereafter produce fruit; so he asked Mr Barlow to give him a couple of trees, and Mr Barlow told him to go into the nursery and take his choice. Accordingly Tommy went, and chose out two of the strongest-looking trees he could find, which, with Harry's assistance, he transplanted into the garden in the following manner:--They both took their spades and very carefully dug the trees up without injuring their roots; then they dug two large holes in the place where they chose the trees should stand, and very carefully broke the earth to pieces, that it might lie light upon the roots; then the tree was placed in the middle of the hole, and Tommy held it upright while Harry gently threw the earth over the roots, which he trod down with his feet in order to cover them well. Lastly, he stuck a large stake in the ground and tied the tree to it, from the fear that the wintry wind might injure it, or perhaps entirely blow it out of the ground. Nor did they bound their attention here. There was a little spring of water which burst forth from the upper ground in the garden, and ran down the side of the hill in a small stream. Harry and Tommy laboured very hard for several days to form a new channel, to lead the water near the roots of their trees, for it happened to be hot and dry weather, and they feared their trees might perish from the want of moisture. Mr Barlow saw them employed in this manner with the greatest satisfaction. He told them that in many parts of the world the excessive heat burned up the ground so much that nothing would grow unless the soil was watered in that manner. "There is," said he, "a country in particular, called Egypt, which has always been famous for its fertility, and for the quantity of corn that grows in it, which is naturally watered in the following extraordinary manner:--There is a great river called the Nile, which flows through the whole extent of the country; the river, at a particular time of the year, begins to overflow its banks, and, as the whole country is flat, it very soon covers it all with its waters. These waters remain in this situation several weeks, before they have entirely drained off; and when that happens, they leave the soil so rich that everything that is planted in it flourishes and produces with the greatest abundance."
