CONVEYANCE OF CHINCHONA-PLANTS AND SEEDS FROM SOUTH AMERICA TO INDIA.
The attempt to make simultaneous collections of seeds and plants of all the valuable species of chinchonÆ was thus crowned with almost complete success. Out of my original scheme the C. lancifolia of New Granada was the only one which had not been procured. It is unnecessary to say more respecting the numerous difficulties and dangers which were encountered by the collectors, for the narrative of the proceedings detailed in previous chapters will have made these sufficiently obvious. So far as the labours in South America were concerned, all obstacles were surmounted, and the objects of this great enterprise were fully attained. Not only were plants and seeds safely brought to the coast, but, in every instance, the collectors took care to provide themselves with botanical specimens from the chinchona-trees. Thus the leaves, flowers, fruit, and bark of each species, which were brought to England, placed the identity of the valuable species to which the plants and seeds belonged beyond the remotest possibility of a doubt. There was not much reason for apprehension with regard to the seeds; but the plants, in the absence of any provision for conveying them direct across the Pacific, had to undergo an ordeal of unprecedented duration. Yet the great advantage of introducing plants as well as seeds, in the immense start they would give to the young plantations in India, was strongly felt, and the complete success that attended the hazardous transit of at least one relay, which came under peculiarly favourable circumstances, fully justified the attempt. I gave directions to Mr. Spruce and Mr. Pritchett to send small parcels of seeds of each species to Jamaica and Trinidad, in obedience to an order received from England, so that quinine-yielding trees might also be introduced into our West Indian colonies; and the results of the experiment in those islands will be given in a future chapter. The great bulk of the collections, however, were despatched to India, by the roundabout way of Southampton, directly they arrived on the coast of the Pacific. The thirty Wardian cases which I sent out round Cape Horn were three feet two inches long, ten feet ten inches broad, and three feet two inches high; and, with soil and plants, each case weighed a little over three hundredweight. The collection of plants of C. Calisaya, C. ovata, and C. The "grey-bark" seeds arrived in the Neilgherry hills early in January, 1861, and the "red-bark" in the following Thus, in spite of one or two disappointments, the great object of the undertaking sanctioned by the Secretary of State for India was fully attained. By the spring of 1861 a large supply of plants and young seedlings was established in the Neilgherry hills; and at the present moment we have thousands of chinchona-plants, of all the valuable species, flourishing and multiplying rapidly in Southern India, and in Ceylon. When the unprecedented length of the voyages and the numerous trans-shipments are taken into consideration, the wonder is that any of the plants should have been successfully conveyed from the slopes of the Andes in South America to the ghauts in Southern India, over thousands of miles, through every variety of climate, and subject to the risk of crossing the isthmus of Panama, of changing steamers at the island of St. Thomas, at Southampton, at Suez, and at Bombay, and of the journey through Egypt. The most important introduction of plants into India, by means of Wardian cases, previous to the arrival of the chinchonas, was that of the tea from China in 1849 and following years by Mr. Fortune. On those occasions the cases were strongly and coarsely made, the glass shades firmly fixed, and the glass itself thick, and glazed in pieces of moderate size. But it was an easy process to convey plants by the short voyage from China to Calcutta, when compared with the introduction of plants from the western coast of South America into India; and the performance of the latter feat, in the case of the chinchona-plants under Mr. Cross's care, is undoubtedly the most extraordinary success of the kind that has yet been achieved. A few remarks on the treatment of plants in Wardian cases were supplied to me by Mr. Weir and Mr. Cross, who acquired their experience in the voyages from South America to India; and by Mr. McIvor, who received the plants on the Neilgherry hills. The cases were filled with soil to a depth of nine to ten inches, in which the chinchonas were planted in rows, from the back to the front of the case. The distance from plant to plant was regulated by their size, but, in the case of their having much foliage, they should be rather wide apart, for the crowding of foliage is always injurious, and often brings on mildew or mould. After having been planted they were well watered, and shaded from the glare of the mid-day sun. On the surface of the soil, between each row of plants, a batten was placed, extending from the back to the front of the case, and held firmly down by two longer With the exception of the false bottom, all the above suggestions were carefully attended to by the gardeners who were in charge of the chinchona-plants during the voyage to India; the partial failures which attended some of the relays from South America could not, under the circumstances, have been avoided by any human foresight; and, as the general result of my arrangements has been to introduce all the valuable kinds of quinine-yielding plants into India, we have every reason to congratulate ourselves on the success of our labours. With the chinchona-plants I brought from Peru a supply of seeds of the chirimoya, of aji-pepper, and of the Schinus molle, all of which are coming up well on the Neilgherry hills. In obtaining plants and seeds of these valuable chinchonas from South America, it would be a source of deep regret to me if that measure was attended by any injury to the people or the commerce of Peru or Ecuador, countries in the welfare of which I have for years taken the deepest interest. But I have no apprehension that such will be the result of the cultivation of these plants in other parts of the world. The demand for quinine will always be in excess of the supply from South America; and the result of chinchona cultivation in India and Java will have the effect of lowering the price, and bringing this inestimable febrifuge within the reach of a vast number of people who are now excluded from its use, without in any way injuring the trade of Peru and Ecuador. I trust that not only will this measure do no injury to the South Americans, but that it may be hereafter productive of good to them, as well as to the rest of mankind. Hitherto they have destroyed the chinchona-trees in a spirit of reckless short-sightedness, and thus done more injury to their own interests than could possibly have arisen from any commercial competition; but it may be that the influence of peace and education will inaugurate a new system in time to come, that more enlightened views will prevail, and that they themselves may undertake the cultivation of a plant which is indigenous to their forests, but which, up to this time, they have so foolishly neglected. It will then be a pleasure to supply them with the information which will have been gained by the experience of cultivators in India, and thus to assist them in the establishment of plantations on the slopes of the eastern Andes. Under any circumstances the South Americans, who owe to India the staple food of millions of their people, and to the Old World most of their valuable products—wheat, barley, apples, peaches, sugar-cane, the vine, rice, the olive, sheep, After much careful consideration it had been decided that the best place for commencing the experimental cultivation of chinchona-plants in India would be the Neilgherry hills, in the Madras Presidency. Here are to be found a climate, an amount of moisture, a vegetation, and an elevation above the sea, more analogous to those of the chinchona forests in South America than can be met with in any other part of India. In the Government gardens at Ootacamund, on the Neilgherries, there were the necessary conveniences for propagating plants and raising seedlings; and in Mr. William G. McIvor, the Superintendent, was to be found a zealous, intelligent, and practical gardener, who had carefully studied the botany of the chinchona genus, and under whose care the cultivation would be commenced with the best possible guarantees for its success. From the Neilgherries the chinchona-plants will, it is hoped, be introduced into such other hill districts of Southern India as, after examination, may be found suitable for their growth; and it was a part of my duty to visit the most promising localities, and, in conjunction with Mr. McIvor, to |
