Whether Linnaeus be right in his conjecture (Spec.  Plant, 1763) that the “Bihai” (Heliconia humilis), a native of Caraccas, which produces fertile seeds, is the stock plant of the plantain, it is almost impossible to ascertain; but the absence of any description of a wild seed-bearing plantain, renders it highly probable that the cultivated species are hybrids produced long ago.  The banana, from time immemorial, has been the food of the philosophers and sages of the East, and almost all travellers throughout the tropics have described these plants exactly as they are known to us, either as sweet fruit eaten raw, or a farinaceous vegetable roasted or boiled.  It is remarkable that the plantain and banana should be indigenous, or at all events cultivated for ages both in the Old and New World.  Numerous South American travellers describe some one of these plants as being indigenous articles of food among the natives, thus showing (if the plantain and its varieties be hybrids) a communication between the tropics of America, Asia and Africa, long before the time of Columbus.  The older writers on the colony of Guiana, as Hartsinck, Bellin and others, consider the plantain to be a native.  It is remarkable that Sir R. Schomburgk, during his travels, found a large species of edible plantain far in the interior.  It appears, therefore, from all the investigations that have been made, that the plantain is either a hybrid, or its power of production from seed has been destroyed long ago by cultivation, and that it is not known to exist anywhere in a perfect state; in which case any attempt to improve the present stock by the introduction of suckers from elsewhere, must be totally futile.  Mr. A. Garnett recommends the following system of cultivation, as calculated to prevent the blight.  The walk or plantation is to be formed into beds 36 feet wide, divided by open drains 30 inches deep.  Two rows of plantains to be planted upon each bed at 18 feet distance, both between and along the rows, to afford a clear ventilation to the enlarging plants, and so soon as the plantation has been established, the space of land between each row to be shovel-ploughed 12 inches deep; the same to be repeated annually, and upon the interspace may be planted maize, yams, sugar cane, or eddoes, and the whole kept clear at all times.  Thus, with the conjoined principles of good tillage, free ventilation, and mixed crops, the blight may yet be successfully combated.

A great diminution in the cultivation of the plantain has been occasioned in British Guiana by this blight or disease, which first made its destructive appearance in Essequibo, upwards of thirty years ago, where its ravages increased with such fatal intensity as to render the profitable growth of the plant almost hopeless; and up to this hour no one has been able to discover the immediate or remote cause of this extraordinary vegetable endemic; whether arising from the action of insects among the sheathes of the petioles of the
