have gone by the time they are ready to be pollenated, and this will 

 result in uneven and poorly developed kernels. This is one indication 

 of the lack of adaptability of that variety of com. Often the tip kernels 

 are irregular in size, shape, indentation, and general appearance due 

 to irregular development, some of the kernels having been fertilized 

 much later than others. This is objectionable. When the tip is not 

 fully filled out those kernels which are fertilized try to occupy the space 

 and in this attempt lose their shape and size. The parallel rows should 

 extend well over the tip, and contain a full number of kernels showing 

 the standard size, shape, indentation, and shading of color. 



Fig. 5. Good and Bad Tips. 



Varieties of corn producing long ears oftener have bad tips than those 

 producing shorter ears. It is the consensus of the best corn growers 

 that a variety producing fully developed tips will give a larger yield 

 than a variety which has a considerable portion of the cob exposed.. 

 Therefore let us look for ears that have tips well covered with uniform,, 

 fully developed kernels, bearing the same indentation and presenting the 

 same proportions as the kernels in the center of the ear. Figure 5 

 gives a good example of a poor and a good tip. 



SPACE BETWEEN KOWS. 



In speaking of space between rows, we find that there are two kinds 

 of space — the space or furrow at the crown of the kernels and the space
