Of Greek exhibitors, inclusive of the Greek Government, there are about thirty-five in number. Of theseonly nine appear with contributions in other than the first four Classes. About twenty-six, consequently,exhibit specimens of the raw materials and produce of their native country. Many circumstances combine torender these peculiarly interesting. The present condition of this once-renowned country, and its naturalcapabilities, form a subject of deep attention to many. The articles exhibited indicate the existence of varioussources of wealth to this country, which appear only to await a vigorous application of the means of industrialprogress to become productive. The vegetable products shown include valonia, madder, currants (the Corin-thian grape), raisins, tobacco, &c. There can be little question that either of these articles, if properly culti-vated, and on a sufficiently extensive scale, would prove more fertile sources of national revenue thanhitherto. A jar of Hymettian honey has classical associations linked with it. The minerals exhibited are,or may readily become, if they can be worked to advantage, and transported at a moderate freight, valuableto commerce. The ornamental marbles, white and coloured, are well represented, and appear as the rawmaterial wrought by ancient art into those monuments of skill which have formed the admiration of everytime and people. The cultivation of the silkworm is extending in Greece , and specimens of raw and manufac-tured silk are sent for exhibition. Specimens of gold embroidery, and some sculptures, are likewise shown.—R.

1 Zapuibakis, Zaphikis, Oythimn, Laconia —

Producer.

Valonia. This article consists of the dried cups of theQuercus cegilops, and is used for tanning.

2 SopniANOS, Andeeas, Zea (Island ) —Producer.Valonia. This article is produced in different parts of

Greece; the best is that of Zea, and the next of Laconia .Annual produce about 140,000 cwts.

[Valonia is used for the purposes of tanning and dyeing.The tree which produces valonia is indigenous to manyparts of Greece . It arrives at maturity from August toOctober. The inhabitants collect it either by shaking thetrees or when it falls naturally; that which falls first iscalled camata, and is in the greatest estimation. There isa large consumption of this product in the tanning esta-blishments of Greece . About 130,000 to 140,000 cwts.are annually exported to Trieste and other parts of theAdriatic, Sicily, the Eoman States, Tuscany, Sardinia , andEngland, in addition to that used in Greece . The prin-cipal ports from which it is exported, are Gythion ofLaconia, Missolonghi, Patras , and Zea. Tho best qualityis produced in the island of Zea, and the next best in'Gytliion, but in considerably huger quantities. It is sup-

plied to the trade during tho months of October andNovember.]

3 MABASTDElirtTS, Andreas, Athens— Producer.

Eour pounds of madder-root, for dye. This plant isgrown in Attica, Euboea , Sciros, &c.; the best quality isthat of Euboea. Annual produce, in all Greece , from4,000 to 5,000 cwts., but it increases yearly.

[Madder-root is used as a red dye: the inhabitantscultivate it for its root, and its cultivation in Greece dates from a very early period, when, according to Theo-phrastus , it was found in a wild state. During thestruggle with Turkey, the growth of this root was neg-lected, but after the restoration of Greece it was againcultivated in many parts, where it succeeds, as the landand climate are very favourable to it, and its dyeing p 1 ' 0 'perties are found to be superior to that grown in manyother parts of Europe . The inhabitants sow it in Feb-ruary in beds of Hglit and thin soils : in order to facilitat 0the development of the root, they surround it with monktwice, and in some parts three times a-year, as by th' 3process the root increases. It is cultivated by the impl 0ments commonly used in Greece , except in Argolis, wher 0some proprietors make use of new and improved inpl°
