In 11 out of 15 comparisons the cross ranges from 2 to 33 per cent 

 lower in yield than the better parent; in the remaining four com- 

 parisons the cross oiityields the better parent by 5 to 23 per cent. 



TEST AT WACO, TEX. 



At Waco the test was located on deep Brazos Valley sand and 

 the corn was drilled in rows 3 J feet apart. A late frost Idlled some 

 of the plants and so interfered to some extent with the uniformity 

 of the stand. For this reason the comparisons of yields, as in the 

 test at Sherman, have been made on the basis of i)roduction per 

 stalk. The stands of three of the crosses were so uneven and irregular
