mixture of seed from other sources. These plots were then in every 

 case the product of a single head ; they showed, in the majority of 

 cases, the greatest variation among the individual canes. 



This variability is well shown by a series of photographs taken by 

 us, which were intended to be reproduced as illustrations of this re- 

 port. Unfortunately the fund provided for such illustrations was ex- 

 hausted at the time this bulletin was sent to the press, so that they had 

 to be omitted. They represent a number of seed- heads, all taken from 

 the same plot, which showed striking variations from either parent 

 type, as well as gradations running back to each. In a plot planted 

 from a single seed-head which was evidently a cross between the Orange 

 and India, for instance, heads were selected which gave the greatest 

 variations and gradations between the India type, with its white seeds 

 and rather loose head, to the Orange, with its reddish-colored seeds and 

 compact head. Another represents the range of variations between the 

 Honduras and Eed Liberiau, two widely different varieties, with the 

 small round seed of the Liberiau type set closely on the sprangle top 

 head of the Honduras. These photographs of the widely different types 

 produced from a single seed-head would convince any one, we think, 

 of the great ease with which variations can be produced in sorghum. 



LIST OF CROSSES. 



The following list gives the number of the experimental plot with the 

 probable parents of some of the crosses grown this season. Many plots 

 are not included, as the characters shown by the canes did not distinctly 

 indicate the origin of the variation.
