1542. CoLEBATCH, W. J. Roseworth Agricultural College harvest report 1919-1920. Jour. 

 Dept. Agric. South Australia 23:059-671, 738-753. 1920. — A report giving yields of grain 

 crops, and results of variety tests of oats, wheat and barley grown under different methods of 

 cultivation and with varying amounts of fertilizers. The data, in most cases arranged in 

 tabular form, compare yield and rainfall in 1919 with those of a series of years. — Anthony Berg. 



1543. Ehrenberg, Paul. Versuch eines Beweises fiir die Anwendbarkeit der Wahr- 

 scheinlichkeitsrechnung bei Feldversuchen (zweiter Aufsatz). [Test of the applicability of 

 the probable error calculation in field trials.] Landw. Versuchssta. 95: 157-294. 1920.— Pre- 

 sents data and further substantiates the value of the Gauss formula for calculating the prob- 

 able error in determining the results of field trials. — A. T. Wiancko. 



1544. FuRBY, E. B. Top-dressing lucerne with superphosphate. Field experiments at 

 Yanco. Agric. Gaz. New South Wales 31:699-700. 1920. — Financial net gains of about 

 S36 and $22 per acre resulted from the use of respectively 2 cwt. and 1 cwt. of superphosphate 

 applied in the spring (September). One cwt. of superphosphate applied in the fall showed 

 scarcely any gain, while 2 cwt. gave a profit of about $18. Five check plots were cultivated 

 but not manured. Two additional plots were neither cultivated nor manured. Eleven 

 irrigations were made during the experiment. — L. R. Waldron. 



1545. Gerlach. Die Entbitterung und Verwertung der Lupinen. [Removing the bitter 

 principle and utilizing lupines.] Mitteil. Deutsch. Landw. Ges. 35:619-620. 1920. — The 

 author reviews some of the methods used to refnove the bitter principle from lupine seed. He 

 points out that the high cost of protein in Germany at this time may warrant the expense 

 involved in utilizing the large amounts of protein in lupine seed for cattle feed and even as 

 human food. — A. J. Pieters. 



1546. Hammond, J. W. Green forage crops and corn for fattening Iambs. Ohio Agric. 

 Exp. Sta. Bull. 340. 45-99. 1920. — The first two experiments were designed to compare per- 

 manent bluegrass pasture with rape pasture or with a succession of the three annual cropS — 

 rye, clover, and rape; to secure data on the economy of feeding corn on pasture; and to com- 

 pare the economy of raising lambs in pasture and in dry lot. The third experiment was 

 intended to yield further data on the problems studied in the first two and in addition to 

 compare a combination of rape and bluegrass pastures with either of the two pastures used 

 alone, and to compare Shropshire X Merino with Merino lambs with respect to rate and 

 economy of gains. The fourth experiment was designed to secure data regarding the econ- 

 omy of feeding a full feed and a half feed of corn to lambs on rape pasture and to compare 

 Shropshire and Shropshire X Merino lambs with respect to rate, economy, and character of 

 gains produced on rape pasture. — R. C. Thomas. 



1547. Harris, E. Grading New South Wales wheats. The proposed standards. Agric. 

 Gaz. New South Wales 31: 771-772. 1920.— The three classes are: (1) Australian Hard Red, 

 (2) Australian Hard White, and (3) Australian White. Each class has five grades as follows: 

 Premium Al, Premium B, and Nos. 1, 2, and 3. Respective minimum weights are: 65, 63, 

 60, 58, and 56 pounds per bushel; maximum moisture content ranges from 12.5 to 13.5 per 

 cent and maximum percentage of damaged kernels from 2 to 7 per cent. Most of the Austra- 

 lian export wheat would come under No. 1 Australian White. — L. R. Waldron. 



1548. Harris, Frank S. The agronomist's part in the world's food supply. Jour. Amer. 

 Soc. Agron. 12: 217-225. 1920.— Presidential address.— i^. M. Schertz. 



1549. Heinrich, M. Aufgaben und Ziele der Samenkontrolle. [Problems and aims of 

 seed-control.] Jahresber. Ver. Angew. Bot. 16: 116-123. 1918.
