“The sluicer raises the gates more or less according to the quantity of water required, and closes them carefully at night, in order to avoid all possible danger of an oversupply running into the canal, or the water would soon overflow it and inundate the surrounding country. As a great portion of Holland is lower than the level of the sea, the waters are kept from flooding the land only by means of strong dikes, or barriers, and by means of these sluices, which are often strained to the utmost by the pressure of the rising tides. Even the little children in Holland know that constant watchfulness is required to keep the rivers and ocean from overwhelming the country, and that a moment’s neglect of the sluicer’s duty may bring ruin and death to all.” “Very good,” said the teacher. “Now, Susan.” “One lovely autumn afternoon, when the boy was about eight years old, he obtained his parents’ consent to carry some cakes to a blind man who lived out in the country, on the other side of the dike. The little fellow started on his errand with a light heart, and having spent an hour with his grateful old friend, he bade him farewell and started on his homeward walk. “Trudging stoutly along the canal, he noticed how the autumn rains had swollen the waters. Even while humming his careless, childish song, he thought of his father’s brave old gates and felt glad of their strength, for, thought he, ‘If THEY gave way, where would Father and Mother be? These pretty fields would all be covered with the angry waters--Father always calls them the ANGRY waters. I suppose he thinks they are mad at him for keeping them out so long.’ And with these thoughts just flitting across his brain, the little fellow stooped to pick the pretty flowers that grew along his way. Sometimes he stopped to throw some feathery seed ball in the air and watch it as it floated away; sometimes he listened to the stealthy rustling of a rabbit, speeding through the grass, but oftener he smiled as he recalled the happy light he had seen arise on the weary, listening face of his blind old friend.” “Now, Henry,” said the teacher, nodding to the next little reader.
