352 EXPERIMENT STATION RECORD. 



lighter weight of leaf and a higher percentage of mineral substance and resin to the 

 change in trannpiration and assimilation due to the lifting of the plants. This 

 method is stated to be successfully practiced in a small district in Herzegovina. 



Kansas and her wheats ( K(in><(ts State Bd. Agr. Bpt. 1902, No. 81, pp. 1-197, figs. 

 28, maps 3). — A eolL^ction of papers and abstracts dealing with the various phases of 

 wheat culture in Kansas. The combined acreage and yield of winter and spring 

 wheat for each county in 1901 is shown on a map. In addition to the discussions on 

 the culture and uses of Kansas-grown wheat, the insect enemies of the crop are de- 

 scribed and the experience and practice of wheat growing is reported by counties. 

 The abstracts here given are mainly from bulletins of this Department and the 

 experiment stations which have been previously noted. 



Observations on wheat culture in 1902, Desprez (Jour. Agr. Prat., n. ser., 

 4 (1902), No. 32, pp. 182, 183). — This article is a general report on the experiments 

 with wheat in 1902 at Cappelle. Soil, seeding, rotation, and cultivation are (hs- 

 cussed. Attention is called to the progress made in the culture and improvement 

 of wheat by referring to figures from the records of the station, which show that in 

 1852 Ble blanc de Flandre yielded from 1,600 to 2,400 kg. of grain and from 4,000 to 

 5,000 kg. of straw per hectare; in 1870 the yields varied from 2,400 to 3,000, and 

 from 5,000 to 7,000 kg. of grain and straw respectively; and in 1896 the production 

 ranged from 3,000 to 3,900 kg. of grain and from 7,000 to 8,600 kg. of straw per 

 hectare. 



Manure experiments with wheat, F. B. Guthrie and R. Helms {Agr. Gaz. 

 New South Wah'x, 13 (1902), No. 6, pp. 06 1-666).— Tabulated results of fertilizer experi- 

 ments with wheat carried on at the Wagga Experimental Farm in 1901 are presented. 

 The action of superphosphate was most marked, while sulphate of ammonia and 

 potash had but very little effect. Superphosphate and Thomas phosjjhate gave 

 about equal results. 



HORTICULTURE. 



A handy book of horticulture, F. C. Hayes (Loudon: John Murray, 1901, pp. 

 225, pis. 9, figs. 9). — This book is not a scientific treatise on horticulture, but rather 

 a popular, practical work, suitable for placing in the hands of beginners in garden- 

 ing. In the first chapter the general principles of gardening are discussed and some 

 practical notions given regarding the nature and management of soils, fertilizers, 

 hotbeds, cold frames, garden pests, seeds, budding, etc. Part II discusses gardens 

 and borders most suitable for different seasons of the year; here directions are given 

 for the growing of roses, ferns, shrul:)s, climbers, vegetables, fruits, etc. Part III 

 discusses the various types of hardy flowers, 21 different groups being noted. Part 

 IV is a calendar of the garden for the different months. The work as a whole is 

 very well adapted to the purpose for which it is written, viz, an introduction to the 

 theory and practice of gardening. 



Department of horticulture and gardening, G. Coote ( Oregon Sta. Rpt. 1902, 

 pp. 69-74) ■■ — This is a brief rejiort on the work of the horticulturist during the year, 

 concisely indicating the results secured in tests of a large nund:)er of vegetal^les and 

 small fruits. In a test of surface v. subirrigation for celery on a small scale, the 

 results on the whole were in favor of surface irrigation. The Self-Blanching variety 

 of celery proved a much earlier variety than the Golden Self-Blanching. Dry 

 Weather cauliflower is stated to be especially adapted to the climate of the station, 

 and has proved the best of all varieties tested for 3 years. It possesses the peculiar- 

 ity of starting into new growth from the collar of the plant after the head has been 

 cut away, thus producing a second crop during the latter part of August and first of 

 September.
