erable degree, by the gradient of the land, and just as steep
northern slopes will be very cool, and steep eastern slopes moderately so,
so will steep southerly and steep westerly gradients be extremely hot. The
heat and coolness of the land, then, is constantly varying, not only with
the aspect, but with the steepness of the gradients, and both of these
points must be taken into consideration in regulating the quantity of
shade required; and the reader will therefore see how impossible it is to
give more than a general guide towards the quantity of shade required, and
all I can undertake to say is that about twice as much shade is required
on a southerly as on a northerly slope, that rather more shade is required
on a westerly than on an eastern aspect, and that the last named requires
less than a southerly aspect.
But this question is further complicated by the varying quality of the
soil.
For our soils vary much in the same plantation, and require a greater or
less degree of shade accordingly. The lighter and drier soils, of course,
require not only more shade, but different kinds of trees, and in the case
of such soils jack and cub busree should be freely used, and especially
the former.
The quantity and quality of the shade required is also complicated by
considerations as regards wind, and, where the soil is exposed to drying
east winds, more shade should be put down than would otherwise be
necessary, had we only to deal with the drying caused by the sun's heat.
And in the case of such lands the shade should consist very largely of
jack and other thick foliaged trees, and these should be topped in order
to keep them short and bushy, and thus the more able to shield the land
from the effects of desiccating winds.
And the whole subject is further complicated by questions of elevation and
the varying quantity of rainfall, as the planter is nearer to, or farther
from the Western Ghauts, and here I can only say generally, that the
nearer you go to the Ghauts the less shade you will require, and the
further to the east the more is necessary, but the planter must be guided
here by local experience, as it is impossible to write precisely on the
subject.
Before quitting this branch of my subject, it may be well to show in a
single sentence the overwhelming importance of having well regulated shade
of the best kinds. If, then, the shade is excessive, the coffee will not
bear well, and if it is deficient or compose
