Even when the precious plant is secured, and danger to life and limb is past, the difficulties to be overcome are enormous. To bring a million sterling in gold from Paris or New York under special and vigilant guard, is a process almost simple when compared with the jealous care which has to be expended on the transportation of orchids. It sometimes happens that on opening the cases on arrival in England, a valuable collection is found to have rotted _en route_, and the importer realises that hundreds of pounds have been spent and lives risked, to secure worthless roots! The orchid importer needs a stout heart and unlimited enterprise, and some of us may well wonder how he manages to make the business pay at all when we think of the ambassadors he employs in nearly every clime, of the funds which he has occasionally to place at their disposal, and of the fact that one loss may involve a sum equal to a fair annual income. On the other hand, if he is the lucky possessor of a variety of value, the plant creates the greatest enthusiasm in orchid circles, and is consequently a source of immense profit. We have in these pages taken a rapid glance at the more popular, it may even be said the more romantic, side of the work of orchid collection. Enough has been said, we hope, to show why the study of orchidology is a liberal education. What a wealth of natural history of the most fascinating kind it opens up! Nothing more striking is recorded in nature than the manner in which the bee fertilises the orchid, to give the least adequate account of which would involve another half-dozen pages of this magazine. The majority of us probably would be surprised to learn that but few orchids grow in the ground. They are found often high up on the branches of some monarch of the primeval forest, and the proverbial needle in the bundle of hay might be discovered half a dozen times over whilst the collector is searching for a single plant. Others appear, however, quite low down. The tree-growing orchid is an epiphyte. That is to say, though it lives on the tree it makes the branch a resting-place only. It gets its nourishment from the atmosphere and not the tree, as does the mistletoe for instance. One orchid, a _Diacrium_, actually grows on rocks within reach of the spray from the salt sea waves.
