Note 203 — Chapter XXIV · IN THE PLANTING DISTRICTS
Reading edition
These problems have to be puzzled out with regard to each separate product. For instance, with regard to coffee, it is found that on elevations of from 2,000 to 6,000 feet above the sea no shade is required, as the clouds suffice. But at lower levels moderate shade is found advantageous, especially if afforded by remunerative trees, such as cacao-shrubs, which in their turn can be shaded by tall cocoa-palms.
