RETURN TO REIKEVIG. 
some leaves of Viccinium uliginosum . The co 
lor, imparted by this process, to judge from some 
cloth shown me, was a pale and pleasant, though 
not a brilliant, yellow. 
Thursday, 
July 20. 
Owing to the continuance of the rain, 
it appeared to be useless to remain 
longer in Almannegiaa; therefore, after spending * 
dark, but excellent, yellow. A deep brown dye is produced 
by boiling the cloth in water with a quantity of the leaves of 
the Sortilyng or Arbutus Uva Ursi, in the same way as prac¬ 
tised with the Lichen islandicus; and in case it is afterwards 
desirable to make this cloth black, some fat earth of that color, 
called Sorta , is collected, put into a vessel of water, and stirred 
about briskly, till it has acquired the consistency of paste; in 
which state, if suffered to stand a little time, the lower part 
stiffens into a thicker substance, and a liquid floats on the 
surface, which being poured off, what remains is daubed over 
the cloth whilst the leaves of the Sortilyng are still attached to 
it: the cloth then, having been rolled upon a cylinder, is boil¬ 
ed, together with the paste, for some hours; taken from the 
vessel; suffered to cool and washed in fresh and cold water. 
Dr. Westring, in his admirable work upon the dying qualities 
of various lichens, has given a figure of Lichen islandicus and 
specimens of four colors that may be extracted from it, by 
different processes; a pale bright yellow, a rusty red, and 
two modifications of brown.—I am happy in the opportunity 
of recommending to the attention of my countrymen this j 
beautiful and elaborate performance, a translation of which j 
(from the Swedish language in which it is written) might, 
possibly be of considerable service to some of our British 
manufacturers.
