course, as we do in marking out for planting. Thus 

 will the wheel tracks and holes be so numerous, as to 

 render it very difficult, if not impossible, for the worm to 

 arrive at the corn. It may appear strange, that these ver- 

 min can crawl up the sides of a clean tin cup, and yet 

 are unable to raise themselves up the inclined sides of a 

 very shallow trench, if the ground be light and crumb- 

 ling. These facts I have ascertained by experiments ; 

 and therefore conceive, that the worm, in searching for 

 the corn, will get into the track, which will conduct it to 

 the hole, into which it will be precipitated, and there pe- 

 rish. In addition to this, I can state, that I have had 

 the plan in operation, and find it answers completely. 



The pressing and polite invitation you gave me, to 

 furnish the Society with any circumstances in my prac^ 

 tice, likely to promote the interests of agriculture, aided 

 by the desire to be useful, is the only apology I can of- 

 fer, in making this communication, to which I subscribe 

 myself, respectfully and with sincerity, 



Your friend, 



Parke Shee. 

 Mr. Roberts Vaux. 



P. S. My plan of fitting up the wheels, for the pur- 

 pose I have stated, is simple, and may be accomplished 

 in a few hours. If you desire to know it, I will make it 

 the subject of a future communication. P. S.
