HORTICULTURE. 141 



Wheat growing" in Wisconsin, E. J. Delwiche and B. D. Leith (Wiseonsiii 

 Sta. Bui. 233, pp. 3-22, figs. 8). — This bulletin outlines briefly the present status 

 of wheat growing in Wisconsin, and includes reports on results of experiments 

 which for six successive seasons have been carried on at the station at Madison 

 and at the substations in the different sections of the State. In this con- 

 nection are discussed the cause of the decline in wheat growing in Wiscon- 

 sin, the present outlook, and wheat and soil depletion. Under essentials of 

 wheat culture are discussed rotations, soil preparation, good seed, time and 

 manner of seeding, harvesting and threshing, and spring and winter wheat. 



Tabulated data of variety tests of both winter and spring wheats are given, 

 including nearly 30 selections. In general, winter wheat outyielded spring 

 wheat. 



Some variable results of seed testing", G. E. Stone {Massachusetts Sta. Rpf. 

 1912, pt. 2, pp. 22-30). — This paper gives results of purity and germination 

 tests made at about 20 different seed-testing stations of seed taken from the 

 name bulk, and discusses the difficulties underlying the identification of seeds. 

 The seeds used were red clover, timothj^ Kentuclvy blue grass, orchard grass, 

 millet, and alfalfa. Wide variations were obtained from the various stations. 

 The germination of Kentucky blue grass was reported at from 3 to 88 per cent, 

 and orchard grass showed a range of 45 per cent. 



Seed work for the year 1912, G. E. Stone (Massachusetts Sta. Rpt. 1912, 

 pt. 2, pp. 17-21). — This gives results with 285 samples for germination and 

 82 samples for purity tests. A total of 1,517 lbs. seed wag separated. The seeds 

 tested for purity were of unusually high grade. 



"Yellow rattle," as a weed on arable land, Winifred E. Brenchley (Jour. 

 Bd. Agr. [London^, 19 (1913), No. 12, pp. 1003-1009, figs. 2).— Two distinct 

 species of this parasite are noted, Rhinanthtis minor and R. major. Their life 

 history, means of attaching to cultivated crops, especially grasses and cereals, 

 and the method of combating, which consists chiefly of fallow cultivation for 

 a season, are discussed. 



HOKTICULTURE. 



Intensive farming, L. C. Corbett (New York, 1913, pp. 146-\-IV, pis. 8, 

 figs. 3). — This comprises a popular handbook of information on the fundamental 

 practices employed in various types of intensive farming. The subject matter 

 is discussed under the following general headings: The problem, vegetable 

 growing, onions, celery, frame culture, the vegetable forcing industry, fruit 

 growing, small fruits, the citrus industry, plant breeding as a factor in inten- 

 sive farming, seed growing, the nursery an example of intensive crop production, 

 irrigation, animal industry, economics of intensive industries, and the cropping 

 system as a unit. 



Recent progress in Belgian horticulture, Vernieuwe (Internat. Inst. Agr. 

 [Rome], Mo. Bui. Agr. Intel, and Plant Diseases, 4 (1913), No. 9, pp. 1321- 

 1326). — In. this paper the author briefly reviews the recent developments in 

 Belgian horticulture, including the measures employed to maintain and safe- 

 guard the interests of the horticultural industry. 



Malnutrition or overfertilization of greenhouse crops, H. D. Haskins 

 (Massachusetts Sta. Rpt. 1912, pt. 2, pp. 71-79). — An analytic study of green- 

 house soils in which cucumbers and sweet peas made sickly growth leads the 

 author to conclude that imperfect growth and development were due in these 

 cases, as well as in many other cases where plant growth is unsatisfactory, 

 to an annual accumulation of soluble plant food rather than to fungi and bac- 

 teria. With cucumbers the trouble does not usually develop until the third year
