618. In Commerce, Russian Hemp bears the highest value, being 

 quoted in the New York Price currents at $265 to $300 per ton, while- 

 the best American only brinsrs $180 to $220 per ton. The difference 

 appears to be in the caode of preparation, Russian Hemp not being 

 carried to the fermenting point in rotting ; while in the American, in- 

 eipient decay has already set in. In the latter country, two processes 

 are employed, &quot;water-rotting,&quot; and dew-rotting.&quot; In the American 

 federal and mercantile navies Russian hemp is cheifly employed for 

 cordage. &quot;Russian hemp, when kept moist and warm, will lose its. 

 strength in about three weeks ; the American water-rotted in twa 

 weeks; and the dew-rotted iu from five to ten days.&quot; (CrooJc & Co.*
