a deeper entrance of drying atmosphere into the soil. Some surface 

 cultivators bear attachments for smoothing the ground as the machine 

 passes along. 



CULTIVATION OF LISTED CORN. It is an idea with many 

 farmers of the districts where corn is checked entirely, that listing is a 

 slack method of corn culture. In the past listing has been practiced 

 most generally by farmers who grow large areas. Hence the methods 

 of cultivation adopted have been those which accomplished most in 

 the least time. This was often carried lo excess, even to the detri- 

 ment of the crop. Some growers harrow the ridges before the corn 

 comes up, especially if the weeds start early. Others wait until the 

 corn is two or three inches high and then harrow. By both of these 

 systems, clods and corn stubs (if the old row has been listed out) are 

 rolled into the furrow. In the former case these obstructions hold 

 the sprout beneath the surface, and in the latter bury the little plant. 

 In either case the weed seeds which were thrown out on the ridges 

 away from the corn, are now returned to the furrow before the corn 

 has had time to get ahead of their growth. Rolling with a heavy roller 

 has some advantages in that instead of hurling the clods into the 

 furrow, it simply pushes them down, crushing a great many. The 

 idea of these last two methods is to level the ridge for the horses.
