740 EXPERIMENT STATION RECORD. 



calcaratus), the mung bean (P. aureus), the urd (P. nmngo), aud the moth 

 bean (P. aconitifolius). The beans are considered with reference to their bot- 

 any and history, distinguishing characters, yields, and uses in their native coun- 

 tries. They are also compared with other similar legumes and notes are given 

 on previous introductions into this country, together with chemical analyses of 

 the hay and seeds. 



A bibliography of cited literature is included. 



Onion culture, O. M. Moeeis {Washington Sta. Popular Bui. 66 {1914), PP- 

 Jf). — A brief popular treatise on onion culture. 



Recent investigations on solanaceous grafts, L. Daniel {Rev. Hart. [Paris], 

 86 {1914), i^^o- 6, pp. 135-138, figs. 4).— A study of direct and reciprocal grafts 

 between various species of Solanum, such as the pepper, tomato, eggplant, etc., 

 leads the author to conclude that many of the physiologic troubles of plants 

 commonly considered as diseases are in reality due to the employment of antag- 

 onistic stocks and scions. 



Top grafting of fruit trees, O. M. Morbis and C. B. Sprague {Washington 

 Sta. Popular Bui. 67 {1914), PP- 8, figs. 13). — This contains popular directions 

 for top grafting fruit trees by the following methods : Cleft gi-afting, saw kerf 

 grafting, bark grafting, budding, and bridge grafting. 



"Winter sprays: Sulphur-lime wash and crude oil emulsions, A. L. Melandee 

 {Washington Sta. Popular Bui. 64 {1914), pp- 8). — This contains popular direc- 

 tions for the control of orchard pests by winter spraying with lime-sulphur 

 washes and crude oil emulsions, including data as to their preparation. 



Report on insecticides and fungicides licensed, inspected, and analyzed 

 during the year 1913, S. K. Johnson {Agr. Com. Ohio, Off. Rpt. Nursei-y and 

 Orchard Insp., 1913, pp. 31-64)- — This comprises a report of the work for 1913 

 on the inspection and analysis of insecticides aud fungicides imder the Ohio 

 insecticide and fungicide law, the text of which is given. 



Reports on experimental work in connection with, cranberries, H. J. Frank- 

 lin {Massachusetts Sta. Bui. 150 {1914), pp. 37-62). — The author here presents 

 a full report on the work of the cranberry substation at Wareham for the year 

 1913 (E. S. R., 31, p. 441). 



Weather records are being secured at the substation and at various other 

 bogs with the ultimate aim of making more satisfactory frost predictions. 

 Observations of barometric changes with respect to their influence ou frost 

 conditions in the Cape Cod region ha^e shown a need of a more thorough knowl- 

 edge of barometric conditions in the eastern Provinces of Canada. The U. S. 

 Weather Bureau is planning to take such observations. An overhead irriga- 

 tion system was tested on a small scale for drawing frost out of the cranberry 

 vines by applications of cold water before sunrise. The sprayed areas after- 

 ward appeared to show more frost injury than did the surrounding uusprayed 

 portions of the bog and such irrigation systems are also undesirable from the 

 standpoint of expense. In lieu of a better method of frost protection, attention 

 is directed to the practice of sanding the bogs as used with good results at the 

 Wisconsin Station (E. S. R., 28, p. 838). 



The work with fungus diseases was continued on the experimental plats in 

 cooperation with the U. S. Department of Agriculture (E. S. R., 30, p. 143) 

 and a number of spraying tests were carried on by growers. As in previous 

 years the spray plats were treated in part with Bordeaux alone and in part 

 with Bordeaux for early sprayings and neutral copper acetate for the last 

 application. The tabulated results show a mai'ked falling off in yield of the 

 sprayed plats as compared with the surrounding untreated portions of the bog. 

 It is suggested that the vigorous vines resulting from the control of fungus 

 diseases in previous years may have seriously reduced the supply of available
