traffic; the system of culture, the means of transportation, and the course of commerce, were examined by him with minuteness, accuracy, and breadth of vision. He was neither a trader nor a sailor, but a man of letters, a scientific and professional traveller. But it was obvious when he returned, rich with the spoils of oriental study during thirteen years of life, that the results of his researches were worthy of a wider circulation than that which he had originally contemplated. His work was given to the public in the year 1596, and was studied with avidity not only by men of science but by merchants and seafarers. He also added to the record of his Indian experiences a practical manual for navigators. He described the course of the voyage from Lisbon to the East, the currents, the trade-winds and monsoons, the harbours, the islands, the shoals, the sunken rocks and dangerous quicksands, and he accompanied his work with various maps and charts, both general and special, of land and water, rarely delineated before his day, as well as by various astronomical and mathematical calculations. Already a countryman of his own, Wagenaar of Zeeland, had laid the mariners of the world under special obligation by a manual which came into such universal use that for centuries afterwards the sailors of England and of other countries called their indispensable 'vade-mecum' a Wagenaar. But in that text- book but little information was afforded to eastern voyagers, because, before the enterprise of Linschoten, little was known of the Orient except to the Portuguese and Spaniards, by whom nothing was communicated. The work of Linschoten was a source of wealth, both from the scientific treasures which it diffused among an active and intelligent people, and the impulse which it gave to that direct trade between the Netherlands and the East which had been so long deferred, and which now came to relieve the commerce of the republic, and therefore the republic itself, from the danger of positive annihilation.
