An evidence of the jealous care which is exercised to prevent strangers from carrying away any information in detail relative to the island, was evinced to the writer in a tangible form on one occasion in the Paseo de Isabella. A young French artist had opened his portfolio, and was sketching one of the prominent statues that grace the spot, when an officer stepped up to him, and, taking possession of his pencil and other materials, conducted him at once before some city official within the walls of Havana. Here he was informed that he could not be allowed to sketch even a tree without a permit signed by the captain-general. As this was the prominent object of the Frenchman's visit to the island, and as he was really a professional artist sketching for self-improvement, he succeeded, after a while, in convincing the authorities of these facts, and he was then, as a great favor, supplied with a permit (for which he was compelled to pay an exorbitant fee), which guaranteed to him the privilege of sketching, with certain restrictions as to fortifications, military posts, and harbor views; the same, however, to expire after ninety days from the date. The great value and wealth of the island has been kept comparatively secret by this Japan-like watchfulness; and hence, too, the great lack of reliable information, statistical or otherwise, relating to its interests, commerce, products, population, modes and rates of taxation, etc. Jealous to the very last degree relative to the possession of Cuba, the home government has exhausted its ingenuity in devising restrictions upon its inhabitants; while, with a spirit of avarice also goaded on by necessity, it has yearly added to the burthen of taxation upon the people to an unparalleled extent. The cord _may_ be severed, and the overstrained bow will spring back to its native and upright position! The Cubans are patient and long-suffering, that is sufficiently obvious to all; and yet Spain may break the camel's back by one more feather! The policy that has suppressed all statistical information, all historical record of the island, all accounts of its current prosperity and growth, is a most short-sighted one, and as unavailing in its purpose as it would be to endeavor to keep secret the diurnal revolutions of the earth. No official public chart of the harbor of Havana has ever been issued by the Spanish government, no maps of it given by the home government as authentic; they would draw a screen over this tropical jewel, lest its dazzling brightness should tempt the cupidity of some other nation. All this effort at secrecy is little better than childishness on their part, since it is impossible, with all their precautions, to keep these matters secret. It is well known that our war department at Washington contains faithful sectional and complete drawings of every important fortification in Cuba, and even the most reliable charts and soundings of its harbors, bays and seaboard generally.
