flowering and boiling begin, reach their maximum, and concUide. The bulk of the Ist crop is 

 picked from the 21st to 24th week from sowing; (9) cotton stainers (Dysdercns spp.) being now 

 under control, losses of crop are caused mainly by shedding of buds and bolls, and external- 

 boll and soft-rot diseases. Experiments concerning shedding are not yet concluded. Spray- 

 ing is useless in the control of external boll disease, but further experiments are needed to 

 determine its effects on the soft-rot disease. — /. S. Dash.

 Pusa 1919-20: 10-20. S pi. 1920. — The report includes details of crop rotation as practiced 

 on the Institute farm; a summary of the results of jiermanent experiments; details of costs of 

 operations with motorized agricultural implements; and breeding of cattle for milk produc- 

 tion. The best results in cattle breeding have been obtained from crossing native Indian 

 cows and Ayrshire bulls. One cow produced 7705 pounds of milk during a lactation period 

 of 10 months. — Winfield Dudgeon. 



30. Jackson, T. P. Report on the Agricultural Department, Antigua. Imi). Dept. Agric. 

 West Indies Rept. Agric. Dept. Antigua 1918-19: 39 p. 1920.— The author reports: (1) Work 

 in gardens and observations on plants, the latter including notes on Artahotrys odoratissima, 

 Myroxylon Pereiras, and Areca catechu; (2) work in nurseries and distribution of plants, with 

 notes on Eucalyptus rostrata, a tree whose wood bids fair to replace foreign woods for railway 

 sleepers; (3) plot experiments at the Botanic and Experiment Stations,^ — sweet-potato storage 

 and varietal experiments. In the latter experiment, A12 yielded an average of 13,7C0 lbs. 

 per acre after 3-years' trial; Light Red (yam) yielded an average of 20,-373 lbs. per acre. In 

 experiments with Eddoes and Tannias, Tannia Yellow came first with an average yield of 

 4,280 lbs. per acre after 11 years of experiment; in the fodder experiments. Pearl Millet and 

 Early Amber sugar corn tied for first place with yields of 24,000 lbs. per acre; (4) cotton selec- 

 tion; (5) fungous pests and their control, with a note on Marasmius sacchari attacking sugar- 

 cane; (6) progress in the sugar, cotton, lime, coconut, onion and corn industries; and (7) 

 miscellaneous notes on silos and ensilage, reafforestation, plant legislation, etc. — J. S. Dash.

 Upper north coast district. Agric. Gaz. New South Wales 32: 173-lSO. 5 fig. 102!.— Trials 

 were carried out on 9 farms in this district. Yields were excellent due to favorable seasonal 

 conditions. A trial showed that the lighter wheat seeding with field peas gave the largest 

 forage yield. Generally wheat and peas gave better yields than wheat alone or oats alone. 

 Oats alone yielded better than wheat alone. Yields of green forage in excess of 15 tons per 

 acre were recorded. Phosphatic manures increased yields in all cases.— L. R. Waldron.
