ns of mountains, rivers, lines of fortresses, &c., are regarded as permanent lines of defence. The Alpine range between France and Piedmont, with its fortified passes; the Rhine, the Oder, and the Elbe, with their strongly-fortified places; the Pyrenees, with Bayonne at one extremity and Perpignon at the other; the triple range of fortresses on the Belgian frontier — are all permanent lines of defence.

These orders were dispatched from Washington the 26th of June, nearly a month after Hull had begun his march from Dayton. Dearborn's army, on the first of September, consisted of six thousand five hundred regulars and seven thousand militia--thirteen thousand five hundred in all: six thousand three hundred for the Niagara frontier, two thousand two hundred at Sacketts Harbor, and five thousand for Lake, Champlain. Even with this absurd plan of campaign and faulty division of the forces, we might have succeeded if the general had acted with energy, so exceedingly weak were the Canadian means of defence; but instead of taking advantage of his superiority in numbers and the favorable circumstances of the time, he entered into an armistice with the British general, and his whole army of thirteen thousand five hundred men lay inactive till the 13th of October, when the absurd project of crossing the Ni
