in them that complete knowledge of plants which at the

' With the land connection of Danzig with the fortress 

 of Pillau secured, the work of Dunenbau on the Frischen 

 Nehrung was resumed, and it was determined to give 

 more attention to the extension of plantations. 



' In the year 1820, as the town would do nothing more in 

 the matter, the Government of Prussia undertook the work 

 entirely, and appointed for this purpose the Dune-Inspec- 

 tor Krause, who conducted the Dunenbau of the province 

 till 1856. He has given explicit statements in regard to 

 his mode of operations in a manual, or Lehrbitch uber den 

 Dunenbau, prepared and published by order of the Govern- 

 ment. With the entrance of Krause upon his duties 

 there were appropriated 15,000 guilders, and thereafter 

 6,000 guilders annually to the resumed reclaiming, affixing, 

 and improving, of a stretch of dunes from the mouth of 

 the Vistula to Kahlberg, some 6| German miles, or 30 

 British miles long, covering an area of about 5000 jock.* 



'With these monies there were up to 1848, 290,000 

 guilders spent on this land, wherewith some 440 jock of 

 the upper dunes were fixed, and 1330 jock planted with 

 Weisskiefern, white firs, and birches. 



' In 1832, in consequence of an urgent cry for help which 

 was heard from outside this district, from the remains of a 

 village destroyed in the previous century, called Polsk, 

 which were in danger of being again overwhelmed by a 

 rapidly advancing dune, this additional district was taken 

 into consideration, and a special grant of money was made 

 for operations there. 



' There was taken in hand a portion of the Frisch Neh- 

 rung, some 2f German miles [11J British miles] long, 

 extending from Kahlberg to the boundary of East Prussia ; 

 and it was sought to cover with woods about 2500 jock

 fourths of an Imperial acre.
