What reading level is Home School of the Century's Progress; book?
To quickly assess the difficulty of the text, read a short excerpt:
The dangerous organic matter disappears, and ninety-eight per cent of the bacteria is removed. And it is pleasing to note, when one has so much to say of the dangers of bacteria, that the purification is entirely brought about by the action of bacteria working for the good of man. A sand filter bed does not purify water properly until it lias been in operation for a few days, when the top of the bed is covered with a slime in which the bacteria act upon the organic matter in the water and purif...y it. The fact of the purifica- tion was known before the manner in which it was done was understood ; and in those cities where the authorities have acted upon this knowledge and have purified their water supply, the influence upon the death-rate of typhoid fever is almost as marked as those already quoted for typhus fever, while the scourge of cholera has been almost entirely removed from their borders, as many an instance during the late outbreak in Europe could illustrate. It does not contribute to our self-esteem to know that most of the water sup- plies so filtered are to be found abroad.
