THE MEDITERRANEAN NAT' ERA LIST 
situated at a distance of upwards of 100 
miles away, yet the form of the mountain 
was perfectly recognisable. 
In the course of some experiments that 
have lately been carried out on certain 
plantations in the vicinity of Algiers, Sigr. 
Trabut discovered that locusts are liable to 
a disease that gives rise to a high rate of 
mortality among them. 
A fungus parasite has been found grow- 
ing on the bodies of these insects, which 
Trabut has named Botrytis acrid iorium, j 
before whose attacks they rapidly succumb. 
Trabut is now engaged on further ex- ; 
periments for the purpose of ascertaining 
how far it will be possible to cultivate this 
parasite, in order that it may be utilised 
against the noxious insects whose ravages 
o o 
have lately caused such irremediable 
damage to the crops of the country. 
Two manganese mines have been opened near 
Ordou in Trebizond. The one, Bos-Tepeh, is si- 
tuated about a half an hour from town, and the 
other, Alajadam, some two hours to the east near 
the sea. Both seem to be surface mines, yielding 
for the time being about 64 per cent of manganese. 
The final concession has not yet been obtained, 
though Mr. Koerner, the engineer in charge, is 
aliowed the right of shipping the ore to the extent 
of 1000 tons. 
The right of felling trees in the 665,0000 square 
miles of the Kerassond forests, and in the 497,000 
square miles of the Tireboli forests, has been ceded 
by Government to private speculators. 
They are in hopes of realising large profits by 
the sale of timber, firewood &c., in and out of the 
country. The wood obtainable in those parts 
consists mainly of oak, pine, chestnut, fir, birch, 
beech, and cornel.
