The maximum yield of 17 tons was secured from Warden wheat and Golden vetches at Kyogle. Use of phosphates generally produced significantly increased yields.-L. R. Waldron.

3699. MARTIN, F. J., and R. E. MESSEY. Experiments on wheat growing in the Sudan. Wellcome Tropic. Res. Lab. Khartoum, Chem. Sec. Publ. 19. 24 p. 1921.-Over 30,000 acres of wheat are grown in the Sudan, mainly in the provinces of Dongola and Berber. Annual precipitation at Khartoum is 4.9 inches; about 6 irrigations of 4 inches each are applied to the wheat crop. The soil at Khartoum, not considered heavy, contains over 40 per cent of clay. The native wheat is undesirable because of its long growing season, making it liable to attacks of stem rust (Puccinia graminis). Pure line selections were made of native wheats and varieties were imported from other countries. Only the earlier varieties, from Australia, India, and Egypt, have given good results. Even Egyptian varieties are rather late. The best yielding varieties were Firbank and Federation from Australia at about 35 bushels per acre; the native varieties yielded only 25 bushels. Full agronomic notes are given. The thrashed grain was hard and brittle, containing but 8-10 per cent of moisture and weighing up to 70 pounds per bushel. The milled flour was rather dark in all cases owing to primitive milling methods. Determinations were made of protein, dry and wet gluten, gliadin, glutenin, and diastatic capacity. Protein content varied from 9.8 to 10.9 per cent. Diastatic capacity was low. Baking results showed several of the wheats, including 2 native wheats, to produce loaves very nearly as large as those made from rollermilled Australian flour. The varieties Firbank, Federation, and Indian No. 40 are recommended. These varieties show less strength than the best American or Russian wheats. The Sudan climate shortens the growing period of wheats.-L. R. Waldron.

3701. MORTIFEE, A. Observations on Uba cane. South African Sugar Jour. 7: 34-45. 1923. Certain factors make the Uba cane desirable for cultivation in Zululand. It is very hardy, resistant to drought in the higher lands and to floods on the Umfolozi flats, and has unusual ratooning qualities. A peculiarity of the variety is its production of "bull shoots," extremely vigorous and rapid growing shoots which usually appear 8-9 months after cutting. An abnormal increase in moisture causes an increase in the number of these shoots. They contain less sucrose than the plant cane.-C. Rumbold.

3702. NOLTE, O. Beiträge zur Kenntnis der Ernährung der Schmetterlingsblütler. [Contribution to the knowledge of the nutrition of legumes.] Mitteil. Deutsch. Landw. Ges. 38:78-80. 1923.—Varying quantities of nitrogenous fertilizer, mostly sulphate of ammonia, were applied to lupine, serradella, beans, peas, red clover and lucerne. No effect was noted on the 1st 3, but with the last 3 there were some increases. Increases were most pronounced with urea.-A. J. Pieters.

Circ. 45. 8 p. 1922.-Results are given of standard and new varieties grown on valley, hill, and wilt-infected soil. The average values of the increase for 2 years due to the application of 15 pounds available nitrogen per acre from different carriers are reported as $12.82 for ammonium sulphate, $12.67 for nitrate of soda, $9.95 for calcium cyanamid, and $1.60 for cottonseed meal.-J. F. O'Kelly.

3704. O'KELLY, J. F., and ROWLAND COWART. Corn experiments, 1922. Mississippi Agric. Exp. Sta. Circ. 47. 8 p. 1923.-Comparative yields of standard and new corn varieties on valley and hill soils and 3 years' results from the use of nitrates under corn are reported. The use of 15 and 30 pounds of available nitrogen per acre from ammonium sulphate, nitrate of soda, or calcium cyanamid was profitable only in seasons of ample rainfall.-J. F. O'Kelly.

[Investigations on the effect of heavy nitrogenous fertilizing on the propagating value of potatoes.] Mitteil. Deutsch. Landw. Ges. 38: 75-78. 1923.-Five varieties of potatoes were grown (1) on a reasonably fertile field, (2) with heavy excess of ammonium sulphate and nitrate of soda. In practically every case the seed stock from the field heavily fertilized gave smaller returns and showed more diseased hills.-A. J. Pieters.

3706. PATTERSON, T. H. The northern gum lands. New Zealand Jour. Agric. 25: 321-333. 3 fig. 1922.-Results to date indicate that these lands may be successfully and profitably farmed by proper methods. Drainage is often necessary and the land should then be limed. Deep cultivation must be practiced. The soil should not be too fine on top. Detailed data on the different experimental plots are given.-N. J. Giddings.

McGraw-Hill Book Co., Inc.: New York & London, 1923.-The authors aim to present all facts now known about this important economic crop, and to emphasize its value as a human food. The soybean is discussed with relation to its commercial status, botanical history, agricultural history, culture, harvesting and storage, composition, utilization, varieties, structure of seed, oil content, soybean cake or meal, soybean products for human food, table dishes of soybeans and soybean products, and enemies. A bibliography of 600 titles is appended.-Mary R. Burr.

3708. REMH, TH. Beobachtungen über Gaswasserdungüng. [Observations on fertilizing with gaswater.] Mitteil. Deutsch. Landw. Ges. 38: 106–108. 1923.-Gaswater containing 1.1-2.21 per cent nitrogen as ammonia was applied as top dressing to meadows and broadcasted on land in preparation for mangels. Except where the gaswater was considerably diluted an initial injury to the grass was noted, but this injury was overcome and the plots fertilized yielded increases amounting to about 75 per cent of those on check plots treated with ammonium sulphate. Gaswater is recommended, but only in the immediate vicinity of factories as the value of the fertilizer does not warrant high transportation costs.-A. J. Pieters.

3709. SAMSON, HAROLD W. United States grades for potatoes. U. S. Dept. Agric. Circ. 238. 4 p. 1922.—Grading standards recommended by the Department of Agriculture and the U. S. Food Administration in 1917 with a few minor changes recommended in 1919 have proved so satisfactory that they are being generally adopted, and by many states as the official standard. Further slight revision is made by the adding of a U. S. No. 1 small grade. The 4 grades are fully described and included terms defined.-P. L. Ricker.

[The management of meadows and pastures considered economically with respect to cattle breeding and cattle raising.] Mitteil. Deutsch. Landw. Ges. 38: 117–118. 1923.—The price of hay in Germany has increased 5,-7,000 fold since 1913, but prices of potatoes and sugar beets have risen only 4-500 fold. This shows Germany's dependence upon imported feeds. The remedy is in better crops resulting from a careful study of meadows and pastures.-A. J. Pieters.

3711. SHATTUCK, OBIL, and DOUGLAS W. RITCHIE. Growing crops in Harney Valley. Oregon. Agric. Exp. Sta. Bull. 191. 24 p., 15 fig. 1922.-A discussion is given of methods of irrigation and crops adapted to this Oregon region. The different irrigation systems mentioned are: the "border system," "check system," "corrugation system," "furrow system," and "sub-irrigation."-Small cereals and forage crops such as alfalfa, field peas, clovers, and sunflowers do best. Potatoes and root crops can be grown but are not as reliable as cereals and forage crops.-C. E. Owens.

[mimeographed], illus. American Beet Sugar Co.: Arkansas Valley, Colorado. 1922.-A résumé of the weather during 1921 is given and its effects on the crop. Effects are recorded of varying methods in cultivation especially fall plowing, rotation of crops, and thinning, on quality and yield of sugar beets. Analyses of soils, water and fertilizer experiments, sugar beet variety tests, experimental beet seed raising, and notes on treated seed follow. In 1921 there was a severe epidemic of leafspot (Cercospora beticola). The observations on this leafspot are connected with the different phases of the experimental work and form a commentary on the conditions which increased and diminished the virulence of the disease. There are observations on fungous diseases of minor importance, insect pests, and field losses prior to and after topping the beets and using different methods of ensiling the roots.-C. Rumbold.

3715. STILES, E. P. The coast country and clover. Beekeepers' Item 6:45-46. 1922.— White clover (Trifolium repens) is spreading in the coast country of Texas, but it attracts very few honey bees. The soil of the upper Texas coast country is largely a heavy black clay and is often acid. If heavy liming would make it possible to grow white sweet clover (Melilotus alba), the value of the land would be greatly increased.-J. H. Lovell.

3716. STOA, THEODORE E. Varietal trials with oats in North Dakota. North Dakota Agric. Exp. Sta. Bull. 164. 46 p., 6 fig. 1922.-Varietal trials with oats are reported for North Dakota from 7 localities covering periods varying from 2 to 21 years. Mid-season varieties are generally better adapted than either early or late varieties. In the southern portion, early varieties frequently do as well or better than mid-season varieties. Late varieties do well only in northeastern North Dakota. Sixty-day and Kherson are the leading early varieties; Lincoln, Victory, and Siberian are leading mid-season varieties; and White Russian and White Tartarian are the best late varieties. Differences among varieties within any group are not important. While yield of straw is closely associated with height of plant, this yield varies greatly from year to year. Early varieties mature in 75–80 days from emergence. Mid-season varieties require about 10, late varieties 20 additional days for maturity. Early variety oats generally weigh least per bushel. Under normal conditions, oats grown in western North Dakota weigh more than those grown in the eastern portion of the state. Swedish Select, a mid-season variety commonly grown, does not yield well and is rather susceptible to stem rust.-L. R. Waldron.

R. Waldron.

3722. WESTER, P. J. Adlay, a new grain plant from the Orient. Jour. Heredity 13: 221-227. 6 fig. 1922.-Adlay is the native Philippine name for Job's Tears (Coix lachrymajobi L.). While primitive tribes in the Philippines have long used the plant for grain, the author was surprised at the prolificacy of some strains. Seed was taken to Manila, where yields of 3,230 pounds to the acre were obtained. Milling tests in Manila and Washington, D. C., have proved that the grain is adapted for use with modern machinery, and when mixed with flour makes very acceptable bread. Since adlay yields fully as much as rice and does not require flooded paddies for culture, it is suggested that it may become an important tropical grain crop.-R. C. Cook.

3723. WHITTET, J. N. Kikuyu grass in bracken fern country. Agric. Gaz. New South Wales 34: 24-26. 2 fig. 1923.-When Kikuyu grass [Pennisetum longistylum] is planted at 3-foot intervals in drills plowed 3 feet apart in braken fern areas, it quite smothers out the fern. The grass resists frosts and affords valuable pasture.-L. R. Waldron.

3725. WINKLER, E. A. Hubam as a farm crop. Gleanings in Bee Culture 50: 762-763. Fig. 1-2. 1922.-The stalks and roots of the annual white sweet clover, or Hubam clover, are nearly as large as those of the biennial species. The roots of Hubam clover may exceed 6 feet in length. Sown broadcast this variety yields over 4 tons of dry matter per acre, which, if plowed under, is equal to nearly 80 tons of farm manure. It is said to save a year in crop rotation.-J. H. Lovell.
