What reading level is Country Cousins Short Studies in the Natural History of the United States book?
To quickly assess the difficulty of the text, read a short excerpt:
The method will depend upon the age, character, and known hardihood of the object, but the two requisites in all cases are cleanness of water and constant aeration. Turning off the water from one of the pipes, a rubber tube from the air-main is led to it, and it becomes an air-pipe. The jar containing the living specimen is placed on that part of the table at which, by means of the tiles underneath, it can be seen to the best advantage ; a small rubber tube attached to a faucet on one pipe is m...ade to supply to it a steady stream of clean sea-water, and another tube brings fresh air to replace the oxygen exhausted by the animal's respiration ; the overflow takes care of itself, and there is no further trouble.
But this simple proceeding can be trusted only in the case of large, mature, tough animals, such as rarely have the honor of reposing in these scientific precincts. More gentle treatment is usually required, and the methods now successful have only been learned through long and costly experience.
