MAPNEY 



Q-rows like the igname — one kind white, another violet color ; the 

 latter good eating. , 



OCTTMO 



Is another farinaceous root ; it is an Arum esculentum, and belongs to 

 the family of the Aroides ; the tubers about 6 inches long and 1^ inches 

 diameter. Its starch very white and wholesome. 



The plants flourish in a temperature of 22 degrees Centigrade, to about 

 73 degrees Fahrenheit, but do not like it below about 60 degrees Fahren- 

 heit. 



The Wampi [Coochia punctata), a fruit relished by the Chinese, would 

 do well in France, we believe. 



THE FRENCH PLANTATION IN ALGERIA. 



Since the foundation of our colony in Algeria, we have sent them 

 1,146,589 trees — economic, fruit, forest and exotic ; 41,722 shrubs and 

 bushes ; 925,386 young trees, and 2,116,211 plants of herbaceous charac- 

 ter, besides seeds, tubers, &c., &c., of all sorts. Our mulberry and silk- 

 worm do not succeed there as we hoped ; yet one province gave us in one 

 year, 1857, over 3,000,000 pounds of cocoons ; but in the last, only the 

 sixth part of it. 



OLIVES. 



71 varieties. Castor oil plant, 14 varieties. 



RUSSIA : ST. PETERSBURGH. 



[New Horticultural Society under the Presidency of \as Imperial Highnesg, the Grand Duke 



Nicholas.] 



We have received a copy of their statutes, and we are happy to inscribe 

 that society on our list of Corresponding Societies. The American Insti- 

 tute did the same, and sent the volume some time ago. 



PHOTOGRAPHY FOR FARMERS. 



Mr. Bruce recommended the use of photography for farmers, to take the 

 likenesses of a great many of the destructive insects that infest our farms 

 and destroy our crops.
