wall, inside which was found a broad, flat riverbed, after which 

 the land rose evenly as far as the eyesight reached. The coast- 

 wall consisted of marine, stoneless, somewhat sandy clay, the 

 surface of which was cracked in checks about 40 x 100cm in size, 

 with 4 — 8 cm deep furrows between ("Rudemark"). The middles 

 of the checks were devoid of vegetation, somewhat arched (see 

 fig. 26), somewhat granular with nut-sized rounded clumps of 

 clay, the margins cracked, and rather washed out. In the 

 furrows stood: Cassiope tetragona, Vacctnium ullgitiosum, Dryas 

 octopetala f. mitior, Salix arctica v. groenlandica, Pedicularis 

 hirsuta, Silène acaulis, Polygonum viviparmn, and Carex nardina. 

 All of them were low, somewhat lichenized and hardly reaching 

 above the checks. 



In the flat river-bed inside the wall water was only found 

 in a pool, but after digging 1 found it everywhere in a depth 

 of 10 — 30 cm below the even sand-bottom, which was only 

 very thinly covered with Equisetum arvense f. decumbens, 

 whose up to 15 cm long thin stems are half buried in the 

 sand. The bank of the riverbed up to its uppermost edge is 

 covered with Eriophorum Scheuchzeri, which at the bottom, 

 although powerful and tickly tufted, is sterile, whereas the 

 higher placed individuals have innumerable white fruit-tassels. 



Within the low grounds, on the gently rising bottom, are 

 found wide heather-moors made up of Cassiope tetragoua and 

 Salix arctica v. groenlandica. Cassiope is dominant, is tickly 

 tufted, and 8 — 10 cm high. Salix is more scattered, is adpressed 

 to the ground, 4 — 5 cm high, and somewhat surrounded by 

 lichens. Besides were noted in small numbers: Saxifraga de- 

 cipiens, S. hieracifolia, Polygonum viviparmn, Oxyria digyna 

 and Liizula confusa. 



On the heath were found a few feebly depressed hollows 

 with moist bottoms covered with Amhlystegia and Cardamine 

 pratensis, Eriophorum Scheuchzeri, and Equisetum arvense f.
