The third argument is the same used by Jefferson and his party before the War of 1812. He thought that to build war vessels was only to build them for the British, as they would be sure to take them. As to changing the policy of the nation, by increasing our navy, let us hope that it is already changed, and forever. Its policy has heretofore been a Southern policy, a slaveholders' policy; it has discouraged the navy, and kept it down to the smallest possible dimensions, because a navy is essentially a Northern institution. You cannot man a navy with slaves or mean whites; it must have a commercial marine behind it, and that the South never had. Our navy ought never again to be inferior in fighting strength to that of England. In that way we shall always avoid war. As to the plan of defending the Lakes at the mouth of the St. Lawrence, we would ask this question: If the blockade of Wilmington was a task beyond the power of our navy, how would it be able to blockade an estuary from fifty to a hundred miles in width? With these enlarged canals, by which gunboats and monitors could be moved from the Atlantic and the Mississippi to the Lakes, and _vice versa_, and by the system of shore defences recommended some years ago by General Totten, namely, strong fortifications at Mackinaw, perfectly commanding those straits, and serving as a refuge to war steamers, works at the lower end of Lake Huron, at Detroit, and at the entrance of Niagara River, these waters will be protected from all foreign enemies. Lake Ontario will also need a system of works to protect our important canals and railroads, which in many places approach so near the shore as to be in danger from an enterprising enemy. It is recommended by the Military Committee, that a naval depot should be established at Erie, as the most safe and suitable harbor on the lake of that name. If, as is probable, a naval station and depot should be thought necessary on the Upper Lakes, the city of Milwaukee has strong claims to be chosen for its site. There is the best and safest harbor on Lake Michigan, so situated as to be easily defended, in the midst of a heavily timbered country, accessible to the iron and copper of Lake Superior and the coal of Illinois. Milwaukee enjoys one of the cheapest markets for food, together with a very healthy climate. Finally, she is connected by rail with the great Western centres of population, so that all the necessary troops for her defence could be gathered about her at twenty-four hours' notice.
