does not seem that there would be much to fear from the introduc- 

 tion of a limited number of types which had so much in common. 

 It is not clear that it would be desirable to isolate the best type to 

 any further extent than would be possible in the use of the highest 

 yielding ears of the ear-row tests. More than this, would very likely 

 tend toward inbreeding. Furthermore, is any one ready, or likely 

 to be ready, very soon to recognize the best type ? 



It is also suggested by the Connecticut Station that it would 

 be better to do all the ear-row testing of field selected ears at one 

 time, testing some 300 or 500 ears the first year, and basing all 

 future work upon the 4 or 5 best ears found.

So far as the number of ears to be tested is concerned, the 

 more the better, if the larger number can be handled with equal' 

 care. However, a test in which the conditions are not uniform is 

 of very little value. But granting that 500 ears are handled as 

 carefully as 50 or 100, the question arises, would it be better to 

 test these 500 field selections of one season's growth, or would it be 

 better to extend this work over, say, five seasons? Our seasons
