The agricultural and forest products of British West Africa

land is an indication of poverty of soil, although the presence of
heavy forest does not necessarily guarantee the suitability of the
locality, as imperfectly drained land often bears a heavy forest
growth. Good natural drainage is essential, and is nearly always
found where the land slopes and the rock underlying the soil is
friable or deep. Natural drainage can often be improved by artificial
means. The last important condition necessary is the selection of a
position where shade and wind protection can be obtained naturally
to as great an extent as possible. Plantations in valleys, sheltered
by mountain spurs or by belts of high forest, are suitable, and
such formations are met with in many parts of the Gold Coast and
Ashanti. In these localities the climate as well as the positions
and soil obtainable are generally so well adapted for the fruitful
growth of cocoa that, even where the average annual rainfall is as
low as 41 inches (the average at Aburi), plantations are proving
successful, the regular distribution, humidity of the atmosphere,
and the natural shade constituting a compensation for the shortage.
The native planter sows the seeds in small patches or in roughly
prepared beds in the vicinity of water, often in such proximity to
one another as to choke a number of the young plants. This form of
nursery is met with throughout the forests, and it is common to find
circular patches containing two or three hundred plants adjoining
a road. In addition to this, a large number of seedlings are grown
at, and distributed from, the Government Botanic Gardens. Native
plantations are for the most part formed of irregular lines of
trees, generally planted too closely. The evil effect of this
does not become apparent until the trees attain a large size, when
the excessive shade they afford to their fruit-bearing branches,
which in cocoa consist of the trunk and main structure, prevents
the fruit from forming and induces rot through want of evaporation
of moisture. The native planter is slow to recognise this, and
disinclined to remedy the matter by removing some of the trees. The
distance at which cocoa trees are planted by the native is roughly
from 7 to 10 feet apart, whereas that recommended for plantations
in the West Indies and Ceylon varies, with the quality of the soil
and the elevation, from 12 to 15 feet; the latter would be more
suitable for most of the Gold Coast plantations. The advantage
which the native planter sees in his method of planting is, that
in addition to getting a larger number of trees into a given space,
the density of their foliage soon becomes so great that weeds cease
to grow beneath, rendering cultivation unnecessary. Until such a
state has been arrived at, the cutting of weeds is an operation
which may have to be performed twice, or even three times, in the
year. This is the only form of cultivation given, no manure being
used or any breaking of the soil done. In the West Indies it is not
