"New Mark," which once meant Brandenburg at large, is getting subdivided into Mid-Mark, into UCKERmark (closest to the Wends); and in Old Mark and New much is spreading, much getting planted and founded.

In the course of centuries there will grow gradually to be "seven cities; and as many towns," says one old jubilant Topographer, "as there are days in the year,"-- struggling to count up 365 of them.
OF BERLIN CITY.
In the year (guessed to be) 1240, one Ascanier Markgraf "fortifies Berlin;" that is, first makes Berlin a German BURG and inhabited outpost in those parts:--the very name, some think, means "Little Rampart" (WEHRlin), built there, on the banks of the Spree, against the Wends, and peopled with Dutch; of which latter fact, it seems, the old dialect of the place yields traces.

[Nicolai, _Beschreibung der Koniglichen Residenzstadte Berlin und Potsdam_ (Berlin, 1786), i.pp.16, 17 of "Einleitung." Nicolai rejects the WEHRLIN etymology; admits that the name was evidently appellative, not proper, "The Berlin," "To the Berlin;" finds in the world two objects, one of them at Halle, still called "The Berlin;" and thinks it must have meant (in some language of extinct mortals) "Wild Pasture-ground,"-- "The SCRUBS," as we should call it .-- Possible; perhaps likely.] How it rose afterwards to be chosen for Metropolis, one cannot say, except that it had a central situation for the now widened principalities of Brandenburg: the place otherwise is sandy by nature, sand and swamp the constituents of it; and stands on a sluggish river the color of oil.

Wendish fishermen had founded some first nucleus of it long before; and called their fishing-hamlet COLN, which is said to be the general Wendish title for places FOUNDED ON PILES, a needful method where your basis is swamp.

At all events, "Coln" still designates the oldest quarter in Berlin; and "Coln on the Spree" (Cologne, or Coln on the Rhine, being very different) continued, almost to modern times, to be the Official name of the Capital.
How the Dutch and Wends agreed together, within their rampart, inclusive of both, is not said.
