1. Anonymous. Dollar wheat. Agric. Gaz. New South Wales 32: 434. 1921.— The 

 variety originated in Victoria. Although of promise, it yields less than standard varieties. — 

 L. R. Waldron. 



2. Block, August. Praktische Erfahrungen iiber den Anbau von Schmetterlingsblutlem. 

 [Practical experience in the culture of legumes.] Mitteil. Deutsch. Landw. Ges. 36: 278-281. 

 1921. — The author gives an account of methods of culture for beans, peas, and especially 

 clovers. The need for lime on clover is emphasized, and it is pointed out that a light top 

 dressing of nitrogen in the spring makes it possible to cut the 1st crop much earlier than 

 usual. The great benefits to hoed and grain crops following clovers are mentioned, and some 

 estimates are given of increases due to the clover sod. — A. J . Pieters. 



3. Calving, Mario. El Zacate bianco de Honduras. (Ixophorus unisetus Sch.) [The 

 white hay of Honduras.] Rev. Agric. Com. y Trab. [Cuba] 3: 364-366. 3 fig. 1920.— This 

 gramineous plant {Ixophorus unisetus Sch.) was tried as a forage crop on several kinds of soil 

 in Cuba. For best results the seed was planted in a seed bed and transplanted. Watering 

 was necessary in the light dry soils where the first trials were made. In the first 3 cuttings 

 of the 1st year crops up to 99,703 kgm. per hectare were secured. A chemical analysis is given 

 which indicates that as a forage it is richer than Panicuin barbinode or P. inaxijnum. — 

 F. M. Blodgett. 



4. Cutler, G. H. Pure seed distribution and the method employed in Alberta. Sci. Agric. 

 [Canada] 1 : 82-84. 1921. — The author discusses the Alberta Crop Improvement Association, 

 dealing with objects, membership, cooperative experiments, and seed growing centers. — 

 B. T. Dickson. 



5. FiTZ, L. A. Kanred: the new Kansas wheat. Operative Miller 25: 284-285. 1920.— 

 Varietal comparisons with Karkof and Turkey, 2 standard hard red winter wheats, conducted 

 at the Kansas Agricultural Experiment Station during the 8 years, 1912-1919 inclusive, show 

 that Kanred outyielded the other varieties by 2.9 and 3.8 bushels respectively. The average
