eighteen months would do wisely to take a few months
holiday. Beyond what has been told above, there is
nothing in Congo-land to daunt a man; indeed, far
less than in many parts of India, South America, or
the West Indies.
My object, as will have been seen, is to eradicate
this silly fear of the climate. The above rules, if
observed, will prevent at least three-fourths of the
maladies that have punished our imprudent youths.
Possibly the judicious will find reward in following
their guidance as nearly as possible, the injudicious
and unreflecting will also have their reward.
The following tables contain portions of the valuable
meteorological observations of Dr. Danckelman relating
to the climatology of the Congo region :—
