298 EXPERIMENT STATION RECORD. 



1320). — The first paper is a discussion of the alleged discovery by R. 

 Hefehnaiin of ziuc iu dried apples imported to Germany from the 

 United States. It is believed that the minute quantity claimed to 

 have been found would not be injurious to the human system. The 

 accuracy of the chemical analysis is questioned, more care is advocated, 

 and a new method of analysis is suggested and technically described. 



In the second article R. Hefelmann replies to the criticism by F. Fil- 

 singer, denying inaccuracy and careless methods. The method of 

 analysis is detailed, and belief is reaffirmed in the danger of poisoning 

 from the zinc in imported dried apples. 



Cranberry culture, E. Hersey {Agriculture of Massachu.setts, 1893, 

 pp. 365-370). — The writer believes that cranberries can be grown on 

 many bogs now in a wild state. The water should be drawn off by 

 ditches to from to V2 in. below the surface, and a ditch should be dug 

 across the upper end of the bog to further limit the water supply. A 

 reservoir above the bog is recommended, the water from which can be 

 let upon the bog during the winter and kept in by a dam across its 

 lower end. If the bog is covered with grass the sod should be removed 

 and all trees and bushes should be cleared away. From 4 to in. of 

 coarse clean sand or fine gravel is to be spread over the surface and the 

 vines pressed into it, being placed 10 in. apart in 10-incli rows. For 

 the first 2 years the bog should be weeded, after which the vines will 

 usually keep out all weeds and grass. The water should be let upon 

 the bog at the beginning of cold weather and kept there until May, 

 when it should be gradually drained off. In Massachusetts the fruit is 

 usually ripe enough for picking by the middle of September. 



Strawberries, M. H. Beckwith {Ddau-are Sta. Bui. 24, pp. 10). — 

 Descriptive notes and tabulated data for 93 varieties of strawberries. 

 In order to ascertain the best varieties for market use, the culture was 

 of the kind ordinarily em])loyed by growers in that section, and no 

 especial fertilizing was given to the soil. Twelve plants of each variety 

 were planted 2 ft. apart in S.J-ft. rows, and the runners allowed to 

 mat for a year previous to the test. The following varieties are con- 

 sidered best for marketing: Bubach, Brandy wine, Greenville, Harmon, 

 Haverlaud, Michel Early, Mrs. Cleveland, Muskingum, Pearl, and 

 Phillips.
