This is a native of South America, and was intro- 
duced into Europe in the 16th century, where it is 
known by the names of wheat of Turkey, Indian 
wheat, Spanish wheat, &e.(1) Its productiveness 
and other good qualities, have brought it into gene- 
ral use, for it is now found in every part of the globe, 
where its cultivation is not forbidden by the cold- 
ness of the climate. With proper culture, it grows 
well in a great variety of soils; but prefers old and 
rich pasture grounds, artificial meadows, warm loams, 
and moist vegetable mould. 
There are many varieties of this grain, denomina- 
ted from colour, number of rows of the grain, and 
different periods of ripening. The white and the 
yellow (of 8 and 12 rows) are the varieties generally 
preferred. 
Corn, from its bulk, its prolific character and sys- 
tem of roots, must necessarily be a great feeder, and 
draw much of its supplies from the earth; whence 
arises the rule, that it ought not immediately to fol-
