And so it lasts, this pleasant Moldau Valley, mile after mile, on the northern or Lower Moldau, generally straight north, though with one big bend eastward just before ending; and not till near Melnick, or the mouth of Moldau, do we emerge on that grand Elbe Valley,--glanced at once already, from Pascopol or other Height, in the Lobositz times." Friedrich's first problem is the junction with Schwerin: junction not to be accomplished south of Ziscaberg in the present circumstances; and which Friedrich knows to be a ticklish operation, with those Austrians looking on from the high grounds there.

Tuesday, 3d May, in the way of reconnoitring, and decisively on Wednesday, 4th, Friedrich is off northward, along the western heights of Lower Moldau, proper force following him, to seek a fit place for the pontoons, and get across in that northern quarter.

"How dangerous that Schwerin is a day too late!" murmurs he; but hopes the Austrians will undertake nothing.

Keith, with 30,000, he has left on the Weissenberg, to straiten Prag and the Austrian Garrison on that side: our wagon-trains arrive from Leitmeritz on that side, Elbe-boats bring them up to Leitmeritz; very indispensable to guard that side of Prag.

Friedrich's fixed purpose also is to beat the Austrians, on the other side of it, and send them packing; but for that, there are steps needful! Up so far as Lissoley, the first day, Friedrich has found no fit place; but on the morrow, Thursday, 5th, farther up, at a place called Seltz, Friedrich finds his side of the Strath to be "a little higher than the other,"-- proper, therefore, for cannonading the other, if need be;--and orders his pontoons to be built together there.
