 crossways of the field. In purchasing a planter, this factor should 

 be looked into. The valves should work quickly. 



The runner turrow-openers which have always been used on corn 

 planters, sometimes fail to give satisfaction on sod land, or in fields 

 which are crowded with trash. The planter will often ride out, leav- 

 ing the corn uncovered. In an effort to prevent this disc furrow-open-

 which the kernel is to rest. Except under the conditions mentioned 

 these attachments are unnecessary. Both single and double-disc fur- 

 row-openers tend to make the planter harder to guide. 



On the rougher and more rolling corn lands, the concave planter 

 wheel is used because the fields are harrowed immediately after 

 planting. This practice does away with two disadvantages, features 

 of the concave wheel; the tendency to leave a furrow for washing, 

 and the smooth surface which dries out badly. The open wheel is 

 better for level lands not subject to washing. It has a little more
