"You construct six slight square iron frames, each hinged to the other; each, say, two feet square, or the breadth of two common tiles, and shaped on the edges so as to take in tiles;--tiles are to be found on every human cottage. This iron frame, when you hook it together, becomes the ghost of a cubic box, and by the help of twelve tiles becomes a compact field-oven; and you can bake with it, if you have flour and water, and a few sticks. The succinctest oven ever heard of; for your operation done, and your tiles flung out again, it is capable of all folding flat like a book." [Retzow, ii. 82 n.] Never till now had Wobersnow's oven been at fault: but in these Polish Villages, all of mere thatched hovels, there was not a tile to be found; and the Bakery, with astonishment, saw itself unable to proceed. Wedell arrived Sunday evening, 22d July; had crossed Oder at Tschischerzig,--some say by Crossen Bridge; no matter which. Dohna's Camp is some thirty miles west of Crossen; in and near the small Town called Zullichau, where his head-quarter is. In those dull peaty Countries, on the right, which is thereabouts the NORTHERN (not eastern), bank of Oder; between the Oder and the Warta; some seventy miles south-by-east of Landsberg, and perhaps as far southwest of Posen: thither has Dohna now got with his futile manoeuvrings. Soltikof, drawn up amid scrubby woods and sluggish intricate brooks, is about a mile to east of him. Poor Dohna demits at once; and, I could conjecture, vanishes that very night; glad to be out of such a thing. Painfully has Dohna manoeuvred for weeks past; falling back daily; only anxious latterly that Soltikof, who daily tries it, do not get to westward of him on the Frankfurt road, and so end this sad shuffle. Soltikof as yet has not managed that ultimate fatality; Dohna, by shuffling back, does at least contrive to keep between Frankfurt and him;--will not try attacking him, much as Wobersnow urges it. Has agreed twice or oftener, on Wobersnow's urgency: "Yes, yes; we have a chance," Dohna would answer; "only let us rest till to-morrow, and be fresh!" by which time the opportunity was always gone again.
