100 AMERICAN HUSBANDRY. 



fall ploughing of all lands where the preceding crop 

 has been injured by the worm, will be found the 

 most easy and effectual remedy, by destroying the 

 insect while in the larva state, and thus preventing 

 the appearance of the perfect insect. The same 

 worm that is found in the wheat-head we the last 

 year detected in oats, and it is well known to attaek 

 barley ; so that it may be considered the general 

 enemy of all the cereal gramina, and should be 

 guarded against in all. 



[The varieties of wheat are very numerous, and 

 the experiments of Le Couteur prove that the num- 

 ber may be easily increased. Some of the varieties 

 that have been introduced into cultivation lately are 

 clearly superior to the old, both in their productive- 

 ness and the quality of their flour. 



An interesting account of the successful conver 

 sion of a winter wheat into summer wheat may be 

 found in the Genesee Farmer, vol. 9, page 138, and 

 in the Cultivator, vol. 7, page 23. In this case the 

 wheat selected was the flint-wheat, white-berried 

 and beardless ; the product of this, when grown as a 

 spring wheat, is reddish and bearded. 



That new kinds may be produced to take the place 

 of such varieties as, by carelessness in cultivation 

 or age, become deteriorated, is evident ; and the Uni- 

 ted States should institute experiments in wheat as 

 well as the countries of Europe. The Italian spring 

 wheat has been a great acquisition to this state. 

 The following notice of its introduction is from a 

 letter to the editors from Mr. Hathaway, of Rome, 

 the gentleman who brought it to the notice of the 

 public]
