To an active external commerce the protection of a naval force is indispensable. This is manifest with regard to wars in which a State is itself a party. But besides this, it is in our own experience that the most sincere neutrality is not a sufficient guard against the depredations of nations at war. To secure respect to a neutral flag requires a naval force organized and ready to vindicate it from insult or aggression. This may even prevent the necessity of going to war by discouraging belligerent powers from committing such violations of the rights of the neutral party as may, first or last, leave no other option. From the best information I have been able to obtain it would seem as if our trade to the Mediterranean without a protecting force will always be insecure and our citizens exposed to the calamities from which numbers of them have but just been relieved. These considerations invite the United States to look to the means, and to set about the gradual creation of a navy. The increasing progress of their navigation promises them at no distant period the requisite supply of seamen, and their means in other respects favor the undertaking. It is an encouragement, likewise, that their particular situation will give weight and influence to a moderate naval force in their hands. Will it not, then, be advisable to begin without delay to provide and lay up the materials for the building and equipping of ships of war, and to proceed in the work by degrees, in proportion as our resources shall render it practicable without inconvenience, so that a future war of Europe may not find our commerce in the same unprotected state in which it was found by the present?
