Brief descriptions are given of each of tlie ears obtained as the result 

 of tlie crossing. In one case a cross of the foiutli year between Early 

 White Dent and (iolden Poi>corn is described. From the unitbrmity of 

 the ears produced it would appear that this cross is now fixed as a dis- 

 tinct variety. 



Some blue kernels found on ears of corn whose immediate parents 

 were known to have shown no kernels of this color, were planted anil 

 one of the resulting ears was artificially fertilized with jiollen from the 

 same stalk under conditions which kept it Iree from any possible inter- 

 mediate cross. This car contained .370 kernels. 



Of these 20(j were bine, 71 pink, 71 oranjjo-yellow. and 22 pnre white. 



This resnlt seems to he contlnsive evidence tliat the Vdni' of the grains ]>lanted 

 was tilt' jnodutt of ata\ ism. and from the faet that all the ]>lant<'d jjrains weiv bine, 

 the pink, yellow, and white grains in like manner iimst have reverted to other varie- 

 ties. Five other ears from the same seed, hnt not imlnsed — thius heing exposed to 

 the pollen of other varieties — showed the same variation in color, with a slightly 

 smaller )ier cent of bine. 



To show the ijrejxtteney of tlie l)liie corn, a large number of ears fnun other jdats, 

 growing within a ra«lins of 2.5 yards, were examined. About half the number of 

 unenclosed ears had from one to fivf bine kernels, while imt one of the inclosed 

 gave any traces of blue.

 (pp. 314-342, ligs. 1(1). — A brief history of the swcj't potato is given, 

 together with notes and tabulattd data on 14 varieties grown at the 

 Louisiana State Station. In an experiment in which cottonseed meal, 

 muriate of jxitasli, and acid ])hosphate, singly and coml»ined, w<'re 

 applie(l on sweet potatoes of the (leorgia Yam vari«'ty on a soil of dark 

 brown loam, the acid i»hosphate gave the largest yield. Cotton-seed meal 

 seemetl to make the jiotatoes irregular in shap*'. Where sweet potatoes 

 were planted at distani«'s of S, lii, l.~», ami IS inches apart in the row 

 the results favored lo and 18 inches. The following table gives the 

 results of an;Hyses of the varieties tested:
