Snatching from the booth his trusty Brown Bess musket, without waiting to challenge, for he well knew that this was the vanguard of the threatened invasion, he fired at the boat, more for the purpose of giving the alarm than in the expectation of inflicting any damage on the moving object in the uncertain light. The sound of the musket shot echoed and re-echoed between the rocky cliffs, and repeated in loud reverberations its thrilling sound of warning. "Curse him! we are discovered," exclaimed the steersman of the foremost boat, with a brutal oath. "Spring to your oars, lads! We must gain a footing before the guard turns out or it's all up with us. Pull for your lives!" No longer rowing cautiously with muffled oars, but with loud shouts and fairly churning the surface of the water into foam, they made the boat--a large flat-bottomed barge--bound through the waves. Another and another emerged rapidly from the darkness, and their prows successively grated upon the shingle as they were forced upon the beach. The invading troops leaped lightly out with a clash of arms, and at the quick, sharp word of command, formed upon the beach. Meanwhile, on the cliff above, the sharp challenge and reply of the guard, the shrill _reveille_ of the bugle, and the quick throbbing of the drums calling to arms is heard. The men turn out with alacrity, and are soon seen, in the grey dawn, running from their several billets to headquarters, buckling their belts and adjusting their accoutrements as they run. Soon is heard the measured tramp of armed men forming in companies to attack the enemy. Sixty men of the 49th Grenadiers, under the command of Captain Dennis, and Captain Halt's company of militia advance with a light 3-pounder gun against the first division of the enemy, under Colonel Van Renssclaer, who has formed his men on the beach and is waiting the arrival of the next boats. These are seen rapidly approaching, but to get them safely across the river is a work of great difficulty and danger. The current is swift, and the swirling eddies are strong and constantly changing their position. On leaving the American shore, they were obliged to pull up stream as far as possible. But when caught by the resistless sweep of the current, they were borne rapidly down, their track being an acute diagonal across the stream. To reach the only available landing- place, they must again row up stream in the slack water on the Canadian side, their whole course being thus like the outline of the letter 'N'. [Footnote: The present writer has a vivid remembrance of a night-passage of the river under circumstances of some peril. It was in a small flat-bottomed scow. Shortly after leaving the American shore, a tremendous storm of thunder, lightning, rain, and hail burst over the river. The waves, crested with snowy foam which gleamed ghastly in the dim light of our lantern, threatened to engulf our frail bark. The boatman strained
