Note 6 — I

Seaweed is largely used in Brittany as a manure. This seaweed, which is very rich in potash, in lime, and in phosphoric acid, has remarkable fertilizing qualities, to which is due the luxuriance of the ‘golden belt,’ about twelve miles broad, which surrounds the peninsula. The seaweed consists of ribbons from one to two yards long, clinging to the rocks, from which they are stripped with rakes at low tide. It is used after it has been exposed to the air for some time, to allow the rain to carry away the salt with which it is impregnated. In certain districts the seaweed is first used as fuel, the ashes being used as a fertilizer.
