HOW TO GROW GOOD CORN. 179 



our wild, or supposed wild, cereals, with a view of 

 examining side by side the nature and amount of 

 the changes which cultivation would most assuredly 

 produce. 



Rye, unlike either wheat or barley, is not remark- 

 able for a long list of varieties — a fact which may, 

 perhaps, be attributed to the more limited growth 

 of the former than the two latter. Its less extended 

 cultivation must be attributed to its inferior qualities 

 as food; for, though rye is in the main a hardier 

 plant than wheat, and therefore could withstand the 

 evils of a colder climate and colder treatment, yet 

 with the advanced climate — the acclimatization of a 

 country rather than a plant — the superior plant, 

 wheat, everywhere prevails ; and this cause also gives 

 rise to the production of finer varieties, which are 

 thus grown where only coarser ones were possible.
