To quickly assess the difficulty of the text, read a short excerpt:
One dragged the rake at the rear of the boat, while the other two worked at the sides. In this manner a strip of the river bottom 6 feet wide was thoroughly scraped. One crew said that they had gathered 3 tons of mussels in three hours. Of all the shells gathered by the party at various points on the James River, or observed at the clammer's camps, no small ones were seen. Mr. Kennedy, a shell dealer, informed our party that he had prospected the James River from Riverside to its mouth, and had... not found any small shells. The basket-rake implement em- ployed on this river and described above would have taken small shells as well as larger ones had they been present. This pov- erty of young mussels may be due to the fact that long-continued low stages of the river cause the run of fishes that are essential to the reproduction of the mussels to occur only at irregular intervals (see also p. 12). We were told by the people who live along the river that in some years fish appear in large numbers, but that usually the fishing was very poor, only an occasional bullhead being caught.
