LEUTZE'S WASHINGTON CROSSING THE DELAWARE.--Our readers are aware of the accident by fire which happened some months since to Leutze's nearly-finished picture of Washington Crossing the Delaware, in consequence of which he abandoned it to the underwriters, intending to commence the work anew for the party from which he had received the order to paint it. The underwriters have accordingly paid the insurance, and are now exhibiting the picture in its incomplete state to the public of Cologne, where it meets with high approval. The _Koelnische Zeitung_ says of it: "In this picture the artist has depicted the events of the hour in which the destiny of the Free States of North America was decided for centuries through the boldness of their courageous and prudent leader. The means of continuing the war were almost exhausted; the army threatened in a few days to dissolve itself; the cause of freedom for that continent, with its inestimable consequences for ancient Europe, would have been postponed, no one can tell how long, perhaps for ever. Then the great mind of Washington conceived what the morally debased, reposing enemy thought impossible. He crossed the Delaware with his army in the night, amid masses of floating ice, and, in the twilight of morning, assailed the inactive camp on the other side. The picture reproduces the moment when the great general,--ahead of the mass of the army, which had also just embarked, and part of which are passing off from the shore, and part already struggling with the driving ice,--is steering to the opposite shore in a small boat, surrounded by eleven heroic figures, officers, farmers, soldiers, and boatmen. The tall and majestic form of the man in whose hands at that hour lay the fate of millions, rises from the group, standing slightly bent, forward, with one foot on the bottom of the boat, the other on the forward bench. His mild yet serious and commanding glance seems seeking to pierce the mist of the farther shore and discover the enemy, while intimations of the future grandeur of his country rise upon his mind. Nothing of youthful rashness appears in the expression of this figure, but the thoughtful artist has depicted the 'heart for any fate' of the general and statesman in noble, vigorous, and faithful traits. And what an impulse moves through the group of his companions! Their thought is, 'Forward, invincibly forward, for our country!' This is expressed in their whole bearing, in every movement, in the eyes and features of all. Under the influence of this thought they command the raging elements, so that the masses of ice seem to dissolve before the will and energy of these men. This is a picture by the sight of which, in this weary and exhausted time, one can recover health and strength. Let none miss a draught from such a goblet of nectar. And while we are writing this, it occurs to us that it was at this very hour seventy-four years ago, in the ice-cold night, Washington crossed the Delaware.
