What reading level is Natural History And Propagation of Fresh-Water Mussels book?
To quickly assess the difficulty of the text, read a short excerpt:
At times, when the field of operations is at some distance from a place where living and sleeping accommodations can be secured, a camping outfit, or a house boat, is used for quartering the crew. The head of the party must be provided wdth a dissecting microscope, a magnifying hand lens, and simple dissecting instruments.
Before an infection can be made, it is first necessary to obtain a supply of glochidia of the desired species of mussels. In localities where commercial shelling is actively ...prac- ticed this can be done by visiting the shellers' boats and examining the catch for freshly- taken gravid mussels. If it is desired to use the glochidia at once, the brood pouches are immediately cut from the females and placed in water; btit if it is desired to use them over a period of several days, the gravid shells are purchased and the glochidia removed as needed. In locations where shells are scarce, or where little or no commercial shelling is done, it is sometimes necessary to hire a sheller to procure the mussels.
