supply in abundance without trenching upon the labour required for 
the promotion of our other industries." 
These gigantic grasses are very common in most tropical regions, many 
of the West India islands abound with them, they cover the sides and 
tops of the mountains throughout the continent of India and form one 
of the peculiar as well as most striking features of oriental and occi- 
dental scenery. The bamboo attains a considerable height, some seventy 
to eighty feet, and has been known to spring up thirty inches in six 
days. 
ITALIAN EXHIBITS AT THE DUBLIN INTERNATIONAL 
EXHIBITION. 
The official duties of the Editor at the Dublin Exhibition, in charge 
of the varied contributions from the Colonies, as in the Exhibition of 
1862, have hitherto prevented his laying before his readers a resume 
of such raw materials and products exhibited by foreign countries, as 
seem entitled to special notice. We now commence with a brief 
notice of the exhibits from Italy, which contributes a much larger col- 
lection of raw materials than any other European country. Most of 
the other States of Europe have restricted themselves to Fine Arts 
and Manufactures. The kingdom of Italy, on the contrary, comes out 
well in all departments, and makes a noble exhibit. 
In the first section, ground and sublimed sulphur may be men- 
tioned, and a fine collection of Sienna earths, shown by Carlo Corbi 
Zocchi, in the various tints of yellow, orange, and dark burnt. Various 
red, white, and dark-grey granites, used for building, are shown by the 
Royal Italian commission. Good specimens of salt are shown by the 
Sardinian Salt Company of Genoa. The works, which are situated near 
Cagliari, belong to the Government, but were leased for thirty years to 
the present company in 1 852. The annual produce of table salt then 
was but 30,000 tons ; now the produce is 140,000 tons, of which the 
Government purchases 52,000 tons, the rest being exported to Norway, 
Sweden, Prussia, and the United States of America ; besides from 6,000 
to 8,000 tons of crude sulphate of magnesia, and 2,000 or 3,000 tons of 
crude sulphate of potash. These two last products are obtained from 
the mother liquor after the deposition of the table salt. 
There are many exhibitors of olive oil. One, Dr. Danielli, shows 
olives preserved in spirits, dried olives, strong olive oil, sweet olive oil,, 
pure white for perfumery, yellow, common dark yellow, common green, 
common white, and other varieties of oil ; olive skins pressed to extract 
the oil with sulphide of carbon ; olive kernel oil for burning, and flour
