- A sample of the oil from each distillation was forwarded to and
examined at the Government Laboratory at Antigua. It is seen that the
average yield of oil per 100 Ib. of the leaves reaped is 178 oz., compared
with an average of 173 oz. on 40 distillations in the previous year. The
interesting fact is also brought out by the data, that there has been con-
siderable improvement in the quality of the oil obtained, as indicated by
the specific .gravity and phenol-content, and a comparison with the
averages obtained in three previous years shows the following
results :—
