Failing in this mode of testing the point, I submitted a few leaves and seed-vessels to my friend, Dr. Dr. H. adds, "Various plants of this natural order are reputed powerful febrifuges, and some of them are said to equal the cinchona in their effects." It is called in the native tongue Kumbanzo. The flowers are reported to be white.
On the eastern flanks, which are watered by abundant rains, the vegetation is exceedingly luxuriant, and here the traveller enters the primeval forests of the tropics. Here is the home of the cinchona tree, here orchids bloom among the tall trunks, and here whole woods are entangled in a network of lianas.
Realizing that the coffee crop is still in an experimental condition, some of the planters are giving their attention to the cinchona, which thrives greatly at Ceylon, even flourishing at elevations where coffee naturally dies out. The seeds of the cinchona are planted in nurseries, and when six months old are transplanted into prepared fields, where they make rapid growth.
We shall see the giant "ceiba" tree, and the "zamang," and the "caoba," twined by huge parasites almost as thick as their own trunks, and looking as though they embraced but to crush them; the "juvia," with its globe-shaped fruits as large as the human head; the "cow-tree," with its abundant fountains of rich milk; the "seringa," with its valuable gum the caoutchouc of commerce; the "cinchona," with its fever-killing bark; the curious "volador," with its winged seeds; the wild indigo, and the arnatto.
It is then left to dry, and afterwards collected and placed in long wooden troughs, where it is stamped fine with heavy wooden stampers. In this condition it is packed into round bales. Finally, both coffee and cinchona are transported by coolies to the nearest railway station. It is in respect of labour that the Javan planters have an advantage over those of Ceylon.
The cascarilleros of South America divide the species into a category of colors, according to the tinge of the bark: there are yellow, red, orange, violet, gray and white cinchonas. The yellow, among which figure the Cinchona calisaya, lancifolia, condaminea, micrantha, pubescens, etc., are placed in the first rank: the red, orange and gray are less esteemed.
After a considerable journey rewarded, it must be said, with a succession of cinchona discoveries they halted near a clearing in the forest, where large heaps of stones and pebbles, arranged in semicircles, attracted their attention.
Other products, and especially cinchona, have received a fair amount of attention in Coorg, and the land on the Ghauts to the westward, where, as we have seen, the coffee plantations have been abandoned, proved to be well suited for the production of the commoner kinds of bark, and large extents of abandoned or semi-abandoned lands were planted with cinchonas.
M. Double, a well-known medical writer and a physician of high standing in Paris, had occasion so long ago as 1801, before he had heard of Homoeopathy, to make experiments upon Cinchona, or Peruvian bark. He and several others took the drug in every kind of dose for four months, and the fever it is pretended by Hahnemann to excite never was produced.
Yet we are far from affirming, that, throughout the whole of the eastern part of South America, from Porto Bello to Cayenne, or from the equator to the 10th degree of north latitude between the meridians of 54 and 71 degrees, the cinchona absolutely does not exist. How can we be expected to know completely the flora of so vast an extent of country?
