Still, you can never wholly circumvent nature. Expel her with a pitchfork, tamen usque recurrit. Now nature has settled that the right way to propagate plants is by means of seedlings. Strictly speaking, indeed, it is the only way; the other modes of growth from bulbs or cuttings are not really propagation, but mere reduplication by splitting, as when you chop a worm in two, and a couple of worms wriggle off contentedly forthwith in either direction. Just so when you divide a plant by cuttings, suckers, slips, or runners; the two apparent plants thus produced are in the last resort only separate parts of the same individual–one and indivisible, like the French Republic. Seedlings are absolutely distinct individuals; they are the product of the pollen of one plant and the ovules of another, and they start afresh in life with some chance of being fairly free from the hereditary taints or personal failings of either parent. But cuttings or suckers are only the same old plant over and over again in fresh circumstances, transplanted as it were, but not truly renovated or rejuvenescent. That is the real reason why our potatoes are now all going to–well, the same place as the army has been going ever since the earliest memories of the oldest officer in the whole service. We have gone on growing potatoes over and over again from the tubers alone, and hardly ever from seed, till the whole constitution of the potato kind has become permanently enfeebled by old age and dotage. The eyes (as farmers call them) are only buds or underground branches; and to plant potatoes as we usually do is nothing more than to multiply the apparent scions by fission. Odd as it may sound to say so, all the potato vines in a whole field are often, from the strict biological point of view, parts of a single much-divided individual. It is just as though one were to go on cutting up a single worm, time after time, as soon as he grew again, till at last the one original creature had multiplied into a whole colony of apparently distinct individuals. Yet, if the first worm happened to have the gout or the rheumatism (metaphorically speaking), all the other worms into which his compound personality had been divided would doubtless suffer from the same complaints throughout the whole of their joint lifetimes.

The banana, however, has very long resisted the inevitable tendency to degeneration in plants thus artificially and unhealthily propagated. Potatoes have only been in cultivation for a few hundred years; and yet the potato constitution has become so far enfeebled by the practice of growing from the tuber that the plants now fall an easy prey to potato fungus, Colorado beetles, and a thousand other persistent enemies. It is just the same with the vine–propagated too long by layers or cuttings, its health has failed entirely, and it can no longer resist the ravages of the phylloxera or the slow attacks of the vine-disease fungus. But the banana, though of very ancient and positively immemorial antiquity as a cultivated plant, seems somehow gifted with an extraordinary power of holding its own in spite of long-continued unnatural propagation. For thousands of years it has been grown in Asia in the seedless condition, and yet it springs as heartily as ever still from the underground suckers. Nevertheless, there must in the end be some natural limit to this wonderful power of reproduction, or rather of longevity; for, in the strictest sense, the banana bushes that now grow in the negro gardens of Trinidad and Demerara are part and parcel of the very same plants which grew and bore fruit a thousand years ago in the native compounds of the Malay Archipelago.

In fact, I think there can be but little doubt that the banana is the very oldest product of human tillage. Man, we must remember, is essentially by origin a tropical animal, and wild tropical fruits must necessarily have formed his earliest food-stuffs. It was among them of course that his first experiments in primitive agriculture would be tried; the little insignificant seeds and berries of cold northern regions would only very slowly be added to his limited stock in husbandry, as circumstances pushed some few outlying colonies northward and ever northward toward the chillier unoccupied regions. Now, of all tropical fruits, the banana is certainly the one that best repays cultivation. It has been calculated that the same area which will produce thirty-three pounds of wheat or ninety-nine pounds of potatoes will produce 4,400 pounds of plantains or bananas. The cultivation of the various varieties in India, China, and the Malay Archipelago dates, says De Candolle, ‘from an epoch impossible to realise.’ Its diffusion, as that great but very oracular authority remarks, may go back to a period ‘contemporary with or even anterior to that of the human races.’ What this remarkably illogical sentence may mean I am at a loss to comprehend; perhaps M. de Candolle supposes that the banana was originally cultivated by pre-human gorillas; perhaps he merely intends to say that before men began to separate they sent special messengers on in front of them to diffuse the banana in the different countries they were about to visit. Even legend retains some trace of the extreme antiquity of the species as a cultivated fruit, for Adam and Eve are said to have reclined under the shadow of its branches, whence Linnaeus gave to the sort known as the plantain the Latin name of Musa paradisiaca. If a plant was cultivated in Eden by the grand old gardener and his wife, as Lord Tennyson democratically styled them (before his elevation to the peerage), we may fairly conclude that it possesses a very respectable antiquity indeed.
