The different places where the timber may be cut are no more than a mile from the respective borders of the lake.
The above mentioned forests are all uncultivated and entirely formed by nature.
The French, about 27 years ago, made a contract with Ali Pasha to cut timber on his territory for their arsenals at Toulon. They established a commercial house at Prevesa directed by monsieur La Salle who built extensive magazines near the port of Prevesa where the timber was deposited. This commerce was carried on till the year 1791. Ibrahim Pasha of Scutari has also in his territories very extensive woods which produce timber fit for building ships of the line. N.B. The cutters are found by Ali Pasha, and are people who live upon the spot.
