their symbiotic nature. In a series of elegant experiments, done while he was a fellow of the National Research Council at the Johns Hopkins University School of Hygiene, Cleveland showocl that the ability of termites to live on a diet of wood or cellulose depends on the digestive capacities of their intestinal flagellates.

In part because of their large size, certain of the flagellates of Cryptocercus provided exceptionally favorable material, but it was Cleveland's exacting microscopy and his application of the then newly available phase contrast methods that led to his beautiful results. He also gave much thought to the role of the centriole and its attendant organelles in cellular division.

Since Cryptocercus occurs, in the eastern United States, only in the Blue Ridge Mountains, Cleveland regularly spent his summers at the Biological Station at Mountain Lake, Virginia, anti, late in his career, at the Biological Station at Highlancis, North Carolina.
