 central portion of Mexico according to researches of J. Harsh. St. 

 Hilaire mentions as its native country Paraguay. A. de Candolle 

 believes it to have come originally from New Granada. Found as 

 cultivated in Central America already by Columbus. This con- 

 spicuous, though annual cereal grass interests us on this occasion as 

 being applicable to far more uses than those, for which it has been 

 employed in most parts of the globe In North-America, for instance, 

 maize is converted into a variety of dishes for the daily table, being 

 . thus boiled in an immature state, as " green corn," Maize-grains pass 

 under the name of Mealies also. Mixed with other flour it furnishes 

 good bread. For some kinds of cakes it is solely used, also for 

 maizena, macaroni and polenta. Several varieties exist, the Inca- 

 Maize of Peru being remarkable for its gigantic size and large 

 grains ; the variety nana is very hardy, having matured seeds in 

 Norway as far north as 63 13' according to Professor Schuebeler. 

 Some varieties in wet tropical countries ripen grain within six weeks 

 from the time of sowing. Maize is not readily subject to the 

 ordinary corn-diseases, but to prosper it requires fair access to pot- 

 ash and lime. It is less exhaustive to the soil than Wheat. Requires
