culture; because nature plainly shows us, that if seeds 

 be either too much exposed to the air, or too deeply 

 buried in the earth, their development must be 

 imperfect. 



As the proper depth at which corn should be sown 

 is of the utmost consequence to the farmer and to the 

 nation at large, the manner of the development of 

 corn seeds may be here portrayed, in order that the 

 cultivator may be convinced that a proper depth is 

 highly necessary to the success of the crop. 



The structure of graminous plants has been al-

The figure A represents the growth from a seed
