SALT-MARSHES OF WEST JUTLAND.

On the Liimfjord, zostera-clad oozes cover many 
hundreds of square miles ; the voyage from Nykjobing- 
Morso to Aalborg occupied a whole day, passing one 
long succession of mud-flats and matchless feeding- 
grounds. But it should be noticed that these waters 
are usually closed by ice from about Christmas till

geese on our north-east coast. 
In the Liimfjord also, we met with schemes for 
reclaiming land from the sea. It will be obvious, as 
this reclamation of the wastes proceeds, that wild-life 
must proportionately decrease, and in process of time 
fens and fen-birds will become as extinct in Denmark 
as they already are in England. 
Among the sand-dunes, or Tclinten , extensive afforest¬ 
ing operations are being carried out by the Danish 
Government, by the destruction of useless ling and 
bents, which are replaced by young pines. This, how¬ 
ever, affects little but the half-starved rabbits, and the 
work affords much highly-valued employment. 
Among the Sand-dunes. 
Along the coast itself lie revler , or mountains of 
sand, bare of vegetation save sparse bents or pale- 
green sword-grass. The revler are lifeless : only colonies 
of terns, and a few pairs of herring-gulls, or oyster- 
catchers, inhabit them. But among the dunes, or 
hlinten , occur inset patches of marshy moor, with 
stagnant pools surrounded by swamp and sedge, bog- 
myrtle, and willow-scrub. 
At one such spot, where there were a hundred
