We traverse the winding lagoon for an hour in continual delight, every passing moment, every quiet turn of our launch or gondola beneath arching bridge or jutting revetement opening up in either direction new and ravishing vistas of architectural beauty. Yet how little have we considered that the very means of our enjoyment, the pure blue waterway upon which our gondola so listlessly floats, is the crowning artifice by which the work of the architect is glorified--a very triumph and inspiration in the great scheme of landscape--say rather waterscape--gardening, which has made this Columbian Fair a unique model for all others of its kind. I think it is conceded by the architects of the Fair that in no way are its buildings to be seen to such satisfaction or full effect as from the lagoon. And it is well to remember, if only as an instructive object-lesson, as we glide upon this liquid street, how much of our present enjoyment is due to the forethought of a supreme design, which, even before a single foundation-wall was laid, had taken into account the most effective grouping of the architectural features. More than this, too, how many of these fortunate architects must have realized the rare satisfaction of having builded better than they knew, when for the first time they viewed their works from the vantage point afforded by their collaborator, the landscape artist, and saw these superb creations given back to them in twofold beauty from the clear mirror of the lagoon. The unique character and important innovation of this lagoon feature may be inferred when we consider that we have here an Exposition covering over five hundred and fifty acres, comfortably filled to its limits with the ample buildings, and yet no vehicles are to be allowed within its enclosure, and none will be required. The circuitous elevated [Illustration: THE BORDER OF THE LAGOON.] railroad will of course transport the multitudes; while by the interior skilful distribution of the water-ways, rippling with gayly caparisoned gondolas by the score, and a hundred trim electric launches and other equally picturesque craft, every portion of the grounds will be easily accessible. The entire circuit on this water-course, from any given point, will occupy nearly an hour. The luxurious tourist arriving at his destination is invited at the water’s edge by ascending terraces of marble steps, their balustrades on either side overtopped by picturesque masses of tropic and other luxuriant vegetation. Huge bronze-like agaves surmount the lofty marble urns; cannas, musas, caladiums, in most effective and artistic groups, are dispersed among broad expanses of velvety sward, begemmed with parterres of brilliant bloom.
