 in 1916. Plants known as "winter annuals" are under discussion. Spurrey (Spergula arven- 

 sis) is described in detail at various stages of growth. It is reported as a useful plant in 

 some countries, but it can be considered only as a noxious weed in New Zealand. Its posi- 

 tion as a weed, and possible control measures are discussed. — N. J. Giddings.

 127. 20 p. Fig. 1-6. 1919. — Darso is a new grain sorghum of unknown origin, possessing 

 superior drouth resisting qualities. It is a dwarf variety of very uniform size, early maturing, 

 leafy, red-seeded. The forage has a higher total sugar content than kafir or feterita. The 

 feeding value of the seed is less than that of black-hulled white kafir. It is recommended as a 

 grain sorghum in the drier regions of Oklahoma, Texas, and Kansas, but not in the more 

 humid regions where other grain sorghums and corn make satisfactory yields. — John A, 

 Elliott.
