8 SEEDS AND PLANTS IMPORTED. 



" Igname ronde de Chine (round yam of China). The tubers made the first 

 season, from plants grown from ' eyes ' dug and replanted, weigh 1^ kilograms 

 each ; the second year the tuber may weigh 4 to 5 kilograms. The plant requires 

 light sandy clay or, better, calcareous, richly fertilized soil. The tubers are 

 gathered at the first frost and stored in the cellar. Storage for two years does 

 not injure but improves the tubers. This yam is an excellent vegetable of 

 delicate flavor and makes delicious fritters, cakes, and souffles. The leaves, 

 after the harvest, are used as cattle feed." (De Xoter.)
