If you were to take an umbrella, and go to visit such a pond in the midst of a shower, and were to look down among the grass, you would see a great many little streams of water flowing down into the pond.

The way to note the rise and fall of water in a lake.

Then if, after the shower was over, you were to put up a measure in the water, and leave it there a few days, or a week, and then visit it again, you would find that the surface of the water would have subsided—that is, gone down. As soon as the rain ceases, so that all fresh supplies of water are cut off, the water already in the pond begins at once to soak away slowly into the ground, and to evaporate into the air. Once I knew a boy who was of an inquiring turn of mind, and who concluded to ascertain precisely what the changes were which took place in the level of a small pond, which lay in a hollow behind his father’s garden. So he measured off the inches on a smooth stick, and marked them, and then he set up the stick in the water of the pond. Thus he could note exactly how the water should rise or fall. There came a great shower very soon after he set up his measure, and it caused the water in the pond to rise three inches. After that it was dry weather for a long time, and the level of the pond fell four inches lower than it was when he first put up the measure.

Lakes among the mountains are often very large, and the waves which rise upon them in sudden tempests of wind and rain sometimes run very high.

The storm on the Lake of Gennesaret. Jesus in the ship.

The Lake of Gennesaret, so often mentioned in the New Testament, was such a lake, and violent storms of wind and rain rose sometimes very suddenly upon it. One evening, Jesus and his disciples undertook to cross this lake in a small vessel. It was very pleasant when they commenced the voyage, but in the night a sudden storm came on, and the waves rose so high that they beat into the ship. This was the time that the disciples came and awoke Jesus, who was asleep in the stern of the ship when the storm came on, and called upon him to save them. He arose immediately, and came forward, and rebuked the winds and the sea, and immediately they became calm.

The adjoining engraving represents the scene. Jesus has come forward to the prow, and stands there looking out upon the waves, which seem ready to overwhelm the vessel. The disciples are greatly terrified. One of them is kneeling near the place where Jesus stands, and is praying to God for mercy. The others are behind. They are equally afraid. The sails have been torn by the wind, and are flying away. Jesus extends his hand, and says to the winds and waves, “Peace! be still!”

The anchor of the ship is seen in the engraving hanging over the bow. But the anchor, in such a case as this, is useless. The water is too deep in the middle of the lake for it to reach the bottom; and, besides, if it were possible to anchor the vessel in such a place, it would do more harm than good, for any confining of the ship, in such a sea, would only help the waves to fill it the sooner.
