arranged so that two of the crosses were planted adjacent to tlie same 

 row of Chishohn. One of the crosses (SchieberleXChishoJm) was 

 cut by mistake when green and fed to stock. Tlie order of phmting 

 the varieties and crosses, and tlieir fiehl-row numbers, together with 

 the results of the test, are shown in Table XI.

The cross outyields the better parent in 8 comparisons out of the 14,

THE THREE TEXAS TESTS CONSIDERED COLLECTIVELY. 



In considermg the three tests collectively the relatively higher 

 production of the Chisholm variety (male parent) at Shei-man than at
