were the best yiclders. — In grcen-manurinp; trials, corn grown on land following field peas 

 outyielded check plat, and this in turn outyicldcd maize following barley and vetches. Low 

 yield of the corn was accounted for by the very heavy crop of barley and vetches. — L. R. 

 Waldron. 



45. Pridham, J. T. Trials of imported cereals. Agric. Gaz. New South Wales 32: 171- 

 172. 1921.— Notes are given on varieties of oats, wheat, and barley imported from U. S. A. 

 and Canada. Of 4 oat varieties, O. A. C. 72, Sixty Day, Banner, and Fulghum, only the 

 Fulghum was of promise. Of the wheat varieties Red Fife, Glyndon Fife, Red Rock, Kanred, 

 Kharkov, Fultz, Marquis, Burbank, Super, Yeoman, and Fenman, none was found to be of 

 promise and all were distinctly inferior to Hard Federation. Barley O. A. C, 21 is evidently 

 worthy of further trial. — L. R. Waldron.

 1921. — In the northwestern district wheat experiments were carried out cooperatively on 15 

 farms; 15 varieties were involved, averaging about 7 varieties to the farm. Hard Federation 

 and Canberra yielded well; Federation was most commonly attacked by stem rust. Experi- 

 ments with barley and oats were only partially successful. — In the central western district 

 trials were conducted on 9 farms, 12 varieties being used. Previous fallowing did not affect 

 smut and take-all. Canberra, Hard Federation, and Yandilla King yielded well. Where 

 a comparison was possible wheat for hay was outyielded by oats. The new oats variety, 

 Sunrise, outyielded Algerian by 10 bushels. Results of manurial experiments were incon- 

 clusive. In 2 cases out of 3 light wheat seeding gave best yields. — In the western district, 

 trials were conducted on 13 farms, 14 varieties of wheat being used. Canberra, Federation, 

 and Hard Federation yielded best. Guyra oats outyielded Sunrise in 2 cases out of 3. Manur- 

 ial trials with superphosphate gave increased yields. Oats for hay gave j'ields equal to or 

 better than those secured from wheat. Large yields of western district are ascribed to favora- 

 ble weather conditions plus available plant food accumulated during the 2 dry years, 1918 

 and 1919.— L. R. Waldron. 



47. RoBSON, W. Report on the Agricultural Department, Montserrat. Imp. Dept. Agric. 

 West Indies Rept. Agric. Dept. Montserrat 1918-19: 52 p. 1920. — The following topics are 

 reported on: (1) Work in the gardens and observations on plants, with notes on Caryocar 

 nucifera, Tecoma spectnbilis, Corypha umbraculifera, Pithecolobium Unguis-cati (generally 

 the most satisfactory of West Indian hedgeplants, but unfortunately a host of I'usciita sp.), 

 and Triphasia aurantiola, which makes a very attractive and shapely hedge. (2) Recent 

 plant importations, including notes on Canavalia gladiata, which has proved satisfactory as 

 a green-manure cover crop and for planting between young lime trees, and Saccharum ciliare 

 (yielding 20 tons of green matter per acre), which may be growm on waste lands and applied 

 as a mulch for young lime trees. (3) Cotton experiments, including extensive notes on cotton 

 breeding work and cotton manurial experiments. (4) Observations on the lime industry. 

 Under this head are discussed the following principal environmental factors connected with 

 the successful development of lime trees: The amount and distribution of the rainfall, — with 

 which is associated the humidity of the atmosphere, — amount of exposure to prevailing winds, 

 damage from scale insects, damage from root grubs, soil medium in which trees are grown, and 

 the manurial requirements of the trees. (5) Sugarcane variety experiments. (6) Experiments 

 with bay trees {Pimenta acris), giving quantities of leaves, results of distillations, etc. (7) 

 Minor crops, including peas, beans, yams,^ — the latter when grown on stakes yielded 79 per 

 cent more than when grown without stakes, — ground nuts, sweet potatoes, — the variety Red 

 Bourbon yielding after 18 experiments an average of 13,034 lbs. per acre.^onions, papaws, 

 Datura metel as a source of Scopolamine, and green manure crops. (8) Diseases, particularly 

 a downy mildew of young lime seedlings which is easily controlled by applying Bordeaux 

 mixture to the plants in the beds. (9) Export figures, etc., on the cotton, lime, sugar, papain, 

 bay oil, and onion industries. (10) Plant legislation. — J. S. Dash.
