e said that the proper regulation of shade is a work of great
importance. It is also one of great difficulty, for the person who marks
the shade trees to be removed must have a thorough knowledge of the kinds
most worthy of preservation, and at the same time bear in mind the
aspects, the gradients, the relation of the earth to the sun during the
hottest months, and the declination of the sun; and, as the planter will
be usually marking shade trees in the morning, he must keep constantly in
view the points where the sun will strike in during the hot afternoon
hours. Then as he looks at a shade tree that has shot up to a great
height, he must consider whether its shade is thrown on the coffee it once
shaded or on to the top of an adjacent shade tree, and, as regards such a
tree, he will often find that he is keeping on his land a tree that is
merely throwing a shade on to another shade tree. I was particularly
struck with this lately when looking at some howligay trees that had shot
up to a great height, and which I at once ordered to be removed, as I
found that their shade was now simply thrown on to the surrounding shade
trees. In short, the trees were now doing no good, and were therefore
merely doing harm by occupying the land and robbing it of food. I have
said that when marking shade the planters must bear in mind the relation
of the earth to the sun during the hottest months, and this caution is
very necessary, because if he should happen to be marking trees in January
for removal after the crop season is over, and does not remember that the
earth is daily shifting its position, he will find that he will have made
many mistakes as to the trees which should be preserved, and that a tree
that is very well placed for blocking out the hot afternoon sun in
January, may be of very little use in March and April.
After a shade tree has been cut down it is necessary, in order to prevent
the stump throwing up suckers, to remove the bark thoroughly from the
stump, and also from any roots that project from the surface of the
ground. If this is not done the stump and its roots will live on and take
up manure intended for the coffee.
It is important to remember that, in many parts of an estate, as the shade
trees become lofty the sun will come in, just as it would on a man's head
if he carried his umbrella erect, and at the end of a long pole, and I
have seen coffee trees so much exposed to the sun as to require fresh
shade to
