"Rhodes grass'' has also been found a serious pest where al- 

 falfa is planted in fields formerly devoted to it, owing to the prev- 

 alence and persistence of its numerous underground stems.

The cultivation of kalo in the Madeira Islands is described 

 by Mr. David Fairchild of the U. S. Dept. Agriculture. He 

 visited Funchal in March, 1907, and writes as follows regarding 

 the ''Igname" (Madeiran name for kalo) : "According to one of 

 the green growers here . . . these Ignamcs sell for 3 cents 

 to 4 cents a pound, while sweet potatoes sell for only 2 cents. 

 Crop comes in February and ends in April. Keep well ; yield 

 about one-third that of sweet potatoes ; plantations continually 

 watered; planting at all times of the year; side root stocks or 

 tubers removed and the central stock left to form a perpetual 

 plantation. The growers in the country boil the tubers before 

 bringing them to market. Then they are brought down from 

 the hills in baskets and sold in this boiled condition for 5 pence 

 (10 cents) a pound. They are very palatable and nourishing, 

 I believe, and rank here as more of a delicacy than the sweet 

 potato. Only two kinds are known here so far as I have ascer- 

 tained." (U. S. D. A. Bur. Plant Industry Bui. 132, p. 59.) 

 The two kinds are the ^'Branca" or white, and the "Vermcilho" 

 or red varietv. Mr. Fairchild reports that "there seems to be little 

 preference given to either of these sorts . . . They are 

 peeled or scraped, and then boiled three to four hours in salt 

 water."

"... Seven species of the Colocasia are found native 

 in Cochin China, two of which are edible ' ' . the Colocasia 

 indica and the Colocasia escnlcnta, known to the natives as 

 Khoia mon sen and Khoia mon sap respectively. The latter, which 

 is by far the best species for food as well as in yield, includes 

 two additional varieties, known as Man ding and Mon mink tia. 



. ' . The cultivation of the edible species should begin in 

 March or April. They require a marshy soil and are planted in 

 ridges like sweet potatoes, about 30 inches apart, with about twice 

 that space between the ridges. Young offshoots from the bottom
