What reading level is The Protection of Fresh-Water Mussels book?
To quickly assess the difficulty of the text, read a short excerpt:


This would be the substantial advantage that such a size limit would have to the mussel beds ; and any advantage to the mussel beds is an ultimate advantage to the fishermen, manufacturers, and all others in any way dependent upon the perpetuation of the mussels. Under the working of a 2-inch size limit, 60 shells out of every 100 then being taken on the niggerhead beds of that vicinity would have been thrown back. This seems to be asking a good deal, but not so much as at first ajipears, for t
...he undersized shells constitute only 38 per cent of the weight or selling value of the shells taken.
On the other hand, both sheller and manufacturer would be saved the trouble of handling over and over again an unnecessarily large number of shells. A ton of shells (from the same locality) com- prising only those above 2 inches in greatest dimension would con- tain about 13,000 pairs, or 37 per cent less than the number now found in a ton (20,500), while these shells, the smallest ones being eliminated, would produce at least 10 i>er cent more buttons of corresponding sizes.
