has been long kept, are boiled in water for two hours ;and the mjœlon being then taken out, a little madder isput into the liquor. The cloth is put in along with themadder, boiled for an hour and a* half or an hour andthree quarters, and afterwards rinsed in water. This dyeis said to be used chiefly for fine cloth, and to give lessharshness than the common black.

What the mjœlon is, we learn from a paper by Linnæusin the fame Transactions for the year 1743- He observes,that about a year before,. a leaf called jackajhapuck wasbrought into England from North-America, and mixedwith tobacco for fmoaking. Mr. Collinfon favoured himwith large specimens of it,, ejxtitled " the plant Jackafha-" puck which is mixed with tobacco, gathered on" Churchill river in Hudfons bay.” This plant, he fays,.was easily known by a Swede, as it grows in Sweden inabundance, on uncultivated gravelly sandy, hills. Hegives its Swedish. names mjœloit, mjœlon-ris, mjœlbœrs-ris ;.and likewise the latin names under which it is describedby different botanic writers, from which it is clear, thatthe mjœlon is the fame with the uva, urfi that has latelycome into esteem in Germany for medicinal use. Somequantity of the n.va urji has been brought from Germany,to be tried as a medicine in this country: the plant israised also in some of our botanic gardens, and. if the pro-pagation of it should be found of any importance, itwould doubtless thrive on many of our now barren hills.

I have been informed by a foreign correspondent, thatthe uva urji is said to be used in England for dying black,and that it is imported for this purpose from Hudfonsbay. I cannot find that this plant, or any other fromHudfons bay, is known among our dyers or dry-salters; .but the two foregoing quotations account sufficiently forthe report.
