layer to the seed.] Jahresbcr. Ver. Angew. Bot. 16: 29-31. 1918. — There is nine times as 

 much fat in the aleurone layer as in the germ; consequently about a million tons of fat from 

 the grain harvest go into the bran each year. This was formerly fed to cattle but during the 

 war was used in bread. Although cattle digest this fat, it passes unchanged through the 

 human alimentary tract. If, however, the cell walls of the aleurone layer are first dissolved 

 by acid, the fat becomes digestible for man. — This fat is deposited in the aleurone layer and 

 hulls of the grain to prevent water from penetrating to the interior. — P. J. Anderson.

 coast district. Agric. Gaz. New South Wales 31:795-797. 1920. — Variety and manurial 

 experiments were conducted in conjunction with farmers. Several varieties of maize from 

 the U. S. A. gave promising results. — L. R. Waldron. 



1562. Makix, R. N. Lucerne on the coast. The south coast. Agric. Gaz. New South 

 Wales 31 : 384-385. 1920.— In selecting a site for lucerne, the nature of the subsoil should be 

 determined to the depth of four feet. In preparing for alfalfa care should be taken to destroy 

 the weeds, as many lucerne failures are due to foul land. Deep plowing and too fine a tilth 

 are inadvisable as the soil has a tendency to puddle and choke the seedlings. Sowings should 

 be made from March to June at the rate of 12 to 16 pounds per acre. When plants have devel- 

 oped the third pair of leaves it should be possible to control weeds and conserve moisture by 

 harrowing without damaging the lucerne. A top dressing of 2 cwt. superphosphate once a 

 year and harrowing after each cutting are recommended. — L. R. Waldron.

 — In a test with varieties of garden peas Yorkshire Hero outyielded all others. Local seed 

 (variety not stated) outyielded introduced seed. Superphosphate was the best fertilizer. —

1565. Munter, F. Pflanzenanalyse und Diingung. [Plant analysis and fertilizers.] 

 Jour. Landw. 68:207-224. 1920.— The results of experiments on Lauchstedt loessal soil. 

 Nitrogen and phosphoric acid fertilizers lowered the sulphuric acid content of barley straw, 

 while lime and magnesia were not materially influenced by nitrogen, potassium, or phos- 

 phoric acid fertilizers. Meteorological conditions of the single year exert so great an influ- 

 ence on the growth of barley that the fertilizer requirement of the soil cannot be deduced 

 with certainty from the percentage of nitrogen, potassium, and phosphoric acid. The nitro- 

 gen content of barley straw was decreased slightly by potassium, more strongly by phos- 

 phoric acid. A straw harvest from 1 hectare containing less than 9 kgm. nitrogen indicates 

 a lack of nitrogen in the soil. The barley plant is not suitable for such experimentation; the 

 proportions of nitrogen to potassium or phosphoric acid give no reliable indication as to the 

 fertilizer status of a soil. Sugar beets are better for this purpose. The production of beet 

 roots in a good growing year was influenced by nitrogen, under poor conditions by phosphoric 

 acid, less by potassium. Beet leaf production depends largely on the nitrogenous fertilizers. 

 The lime and magnesia content of the sugar beet roots was affected only moderately by the
