If historical romance is desired, the prowling is certainly abundant; and if the prowler is a lover of nature, wild and luxuriant, rioting in marvelous and indescribable forms of overflowing life, he has but to equip himself for jungle travel, and he will find wonders by the mile, and fantastic nature piled mountains high and chasms deep. If it is mountains, they are here in scenic beauty unsurpassed. If the explorer is a student of human nature and cares to attempt the unscrambling of this blend of blood that flows in swarthy faces, he will be busy here for a lifetime. And if none of these will do, and the curious landsman will have nothing short of the exploring of vast unchristened wildernesses where no human foot has ever trod, and where strange and dangerous forms of unclassified life wander at will through the overgrown forests, he will find it--and doubtless he will find much more of it than he wants before he gets back to civilization. If it is promotion schemes and development projects, then here at least is a commodious place to put them. Here, in agricultural and colonizing schemes, somebody will yet get rich--and other somebodies poor. If the prowler's interest is primarily social, and he would browse about one of the most interesting cities in America, let him come to Panama. Ancient Spanish streets, scrupulously clean--can these be found anywhere else? Side by side, over and under, the sixteenth and twentieth centuries run together. And what makes Panama to-day the crossroad of the world? For him who in the love of engineering skill holds communion with high human achievement, and prefers to prowl around the locks and docks, and study the marvelous successes and adaptations and devices of the latest and greatest feat of brain and hand, this is the very center of the earth. No man with a soul for the poetry of mechanics can stand in a control house of one of the locks and see the enormous gates swing back at the movement of a finger without feeling that man, with all his limitations, has yet in his being some image of the Creator. To see an ocean giant rise up slowly in the teeth of gravitation and slip through the gates on to the higher level, is to wonder whether the portals that look so gloomy to us may not, after all, be not exits but entrances to a new and higher level of life. What a text! The ship does not rise by straining but by resting in a narrow place. And no ship ever yet got through the locks without a pilot. The whole process is as silent as the forces of eternity. There is a lot more, and it bears no copyright. Help yourself.
