But this solution of her problem was obviously unsatisfactory to England. The northern voyage was long, dangerous and costly; the King of Denmark, who controlled the entrance to the Baltic, had it within his power at any moment to exclude the English traders; the Muscovy company no longer enjoyed exemption from customs in Prussia, Denmark and Russia. In case war should break out among the northern nations this trade might for a time be cut off entirely, resulting in strangulation for England's basic industries. "The merchant knoweth," said the author of _A True Declaration_, "that through the troubles in Poland & Muscovy, (whose eternall warres are like the Antipathy of the Dragon & Elephant) all their traffique for Masts, Deales, Pitch, Tarre, Flax, Hempe, and Cordage, are every day more and more indangered."[1-3] Moreover, the trade was much impeded by the ice which for several months each year choked some of the northern ports. The most alarming aspect of this unfortunate situation was the effect of the shortage of shipbuilding material upon the merchant marine. Situated as it was upon an island, England enjoyed communication with the nations of the world only by means of the ocean pathways. Whatever goods came to her doors, whatever goods of her own manufacture she sent to foreign markets, could be transported only by sea. It was a matter of vital import to her, then, to build up and maintain a fleet of merchant vessels second to none. But this was obviously difficult if not impossible when "the furniture of shipping" such as "Masts, Cordage, Pitch, Tar, Rossen" were not produced in quantity by England itself, and could be had "only by the favor of forraigne potency."[1-4] Already, it was stated, the decay of shipping was manifest, while large numbers of able mariners were forced to seek employment in other countries. "You know how many men for want of imploiment, betake themselves to Tunis, Spaine and Florence," declared one observer, "and to serve in courses not warrantable, which would better beseeme our own walles and borders to bee spread with such branches, that their native countrey and not forreine Princes might reape their fruit, as being both exquisite Navigators, and resolute men for service, as any the world affords."[1-5]
