  • "A specially commissioned report, commending 'the alluvial nature of the soil', listed the valley's crops 'of all kinds from the rarest to the coarsest qualities. Tobacco, the fig, the vine, the olive, the poppy, the cotton plant and mulberry tree are all indigenous products, whilst maize, barley, beans, flax, hemp and a variety of pulse and oleaginous seeds are raised in large quantities. Valonia, yellow-berries, wool, goats' hair, dyestuffs, drugs, skins, honey, wax and likewise abound.' The only hindrance was the primitive condition of the region's Ottoman infrastructure; by revolutionising the pre-industrial carriage of the valley's largely perishable produce, the railway company's backers meant to make a killing."
