"Scientific American Supplement, No. 803, May 23, 1891"

The material sold in three grades--prime, mazzano;
seconds, una aqua; thirds, skart.
The product of Smyrna generally averages:
Tons. Price.
Prime. 2,000 to 3,000 28 florins.
Seconds. 5,000 to 10,000 25 "
Thirds. 20,000 to 30,000 22 "
The _Metilino_ valonia is a product of a neighboring island, and is a
very good article. It may be easily distinguished by its thin cup. It
is harvested in September.
The _Candia_ valonia is nearly as long as it is wide, in contrast to
the Smyrna, which is much wider than long. The recent harvest showed a
return of 800 to 1,000 tons, but no assortment is made. A grade called
the Erstlige is sold, this being the first which has fallen to the
ground before maturing.
A peculiarity of the valonia is that it often strikes out a sort of
sugar sweat, which gives the cup a less attractive appearance, but
denotes the presence of large quantities of tannin.
Valonia is used almost wholly for sole leather, either alone or in
combination with pine or oak bark or knoppern and myrabolams. The
union of valonia and knoppern is that in most general use. Valonia
gives the leather a yellowish appearance, as it deposits a great deal
of yellow bloom. The leather is very firm and of good wearing
qualities. The weight results are also excellent, as will be seen
below.
