 Zealand. New Zealand Jour. Agric. 20: 337-345. 7 jig. 1920.— A comparison is made of 

 the flora on a heavily-grazed and an adjoining lightly-grazed pasture at an elevation of 

 about 2000 feet. Coriaria sarmentosa var. and Celmisia spectabilis are found particularly 

 abundant in the lightly-grazed tract. Coriaria sarmentosa has been reported as poisonous 

 to sheep, but in this instance they were apparently uninjured by it. The Celmisia is reported 

 as unpalatable. — N. J. Giddings.

 Zealand. New Zealand Jour. Agric. 20: 209-217. 8 fig. 1920.— This gives the results of an 

 experiment to determine the relative palatibility for sheep of the native plants occurring 

 in one of the reserves. The plants are listed and relative palatibility noted. — A^. /. Giddings.

 1920. — System of marketing does not offer sufficient inducement for production of better 

 grades of cotton. Investigations in the United States show that best and most uniform 

 fiber can be maintained only in communities which grow a single variety. More attention 

 is needed to determine quality in the field. — 0. A. Stevens.

 In Canada in 1916 in samples of red clover seed, the purple-colored seeds were slightly more 

 prevalent and in practically every case weighed more per thousand seeds than the yellow- 

 colored seeds. Germination tests showed that the yellow seeds gave a higher percentage of 

 germination and contained more hard seeds than the purple. The green or immature seeds 

 gave the lowest percentage of germination, but contained a surprisingly high proportion of 

 hard or impermeable seeds. The brown seeds are shown to be low in vitality and to contain 

 the smallest percentage of hard seeds. — M. T. Munn.
