Table 45 shows the principal sources of our imports of crude naphthalene in recent years. Germany was the principal source until 1936; the United Kingdom, previously the next most important source, was first in 1936 and 1937. In the last three years appreciable quantities have been received from Poland, Czechoslovakia, and the Soviet Union, hitherto unimportant sources.
