Then again there is the marvellous exuberance and novelty of the fauna and flora. And this once more has something better for us all than mere specialist interest. Sugar and ginger grow for all alike. For we must remember that not only do the Tropics represent the vastly greater portion of the world's past: they also represent the vastly greater portion of the world's present. By far the larger part of the land surface of the earth is tropical or subtropical; the temperate and arctic regions make up but a minor and unimportant fraction of the soil of our planet. And if we include the sea as well, this truth becomes even more strikingly evident: the Tropics are even now the rule of life; the colder regions are but an abnormal and outlying eccentricity of nature. Yet it is from this starved and dwarfed and impoverished northern area that most of us have formed our views of life, to the total exclusion of the wider, richer, more varied world that calls for our admiration in tropical latitudes. Insensibly this richness and vividness of nature all around one, on a first visit to the Tropics, sinks into one's mind, and produces profound, though at first unconscious, modifications in one's whole mode of regarding man and his universe. Especially is this the case in early life, when the character is still plastic and the eye still keen: pictures are formed in that brilliant sunshine and under those dim arches of hot grey sky that photograph themselves for ever on the lasting tablets of the human memory. John Stuart Mill in his Autobiography dwells lovingly, I remember, on the profound effect produced on himself by his childish visits to Jeremy Bentham at Ford Abbey in Dorsetshire, on the delightful sense of space and freedom and generous expansion given to his mind by the mere act of living and moving in those stately halls and wide airy gardens. Every university man must look back with pleasure of somewhat the same sort to the free breezy memories of the quadrangles and common rooms of Christ Church or of Trinity. But in the tropical university everybody passes his time in arcades of Greek or Pompeian airiness: the palm-trees wave and whisper around his head as he sits for coolness on his wide verandah; the humming-birds dart from flower to flower on the delicate bouquets that crowd his drawing-room. I knew a lady who made a capital collection of butterflies and moths at her own dinner-table by simply impounding in paper boxes the insects that flitted about the lamp at dessert. Why, if it comes to that, the very bread itself comprises generally a whole entomological cabinet, and contains in fragments the _disjecta membra_ of specimens enough to stock entire glass cases at severe South Kensington. How's that for an inducement to study life where it is richest and most abundant in its native starting-place?
