022 EXPERIMENT STATION RECORD. 



analysis to the director of the New Yorli Agricultural Experiment Station, in 

 accordance with the provisions " of the State fertilizer law. 



Fertilizers, B. C. Aston (.Vew Zeal. Dept. Ayr. Ann. Rpt., l.'i (1906), pp. 

 108-111). — Analyses of a number of typical fertilizers are reported, including, 

 among others, ashes from timljer mills, lish manures, fowl manure, whale 

 refuse, bone ash, basic slags, sterilized bone meal, calcium cyanamid, and castor 

 pomace. 



[Fertilizer market, New York, Chicago, Philadelphia, and Charleston] 

 {Oil, Faint and DriKj li'cparter, 11 {1907), No. 6, pt. J. pp. hl-'iO). — The fertilizer 

 markets of these cities during 1906 are reviewed. It is stated that the year 

 1906 was " a most prosperous one to both the producers and manufacturers of 

 the finished product." The larger use of fertilizers is ascribed principally to 

 the raising of a big cotton crop, the South using during 190G, 500 lbs. of fertilizer 

 to the acre, as against only 200 lbs. two years ago. 



Circulars relating to the fertilizers and feeding-stuffs act, X- H. Elliott 

 {Jour. B(l. A(jr. [Lomloii], 13 {1907), No. 11, pp. G71-67S). — Reprints are given 

 of circulars issued by the Board of Agriculture and Fisheries of (Jreat Britain, 

 giving the rules and regulations adopted by the board for the administration of 

 the fertilizers and feeding-stuffs act of 1906. 



AGRICULTURAL BOTANY. 



Annual review of botany, F. Pechoutre {h'cv. Oi'ii. Sci.. 18 {1907), No. 6, 

 pp. 234-2.'fS. pys. I'j). — A review is given of some of the more important contri- 

 butions relating to chromosome reduction, parthenogenesis, sexuality iu certain 

 hybrids, experimental investigations on the origin of species, and sense organs 

 in plants. 



Botanical and agricultural studies in Java, W. Detmlr {Botauische und 

 landirirt.schaftliviic siiidicii aiif .lava. -Jena: Giistav Fii^clier, 1907, pp. 12Ji, 

 pi. 1). — The author gives the results of his studies made in Buitenzorg during 

 1904 and 1905, the studies including vegetable physiology, forestry, and tropical 

 agriculture. Following a general review of the agricultural practices, in Java, 

 chapters are devoted to comparisons between the plants and climates of Java 

 and Central Europe; studies of .Java soils; accounts of the cultivation of rice, 

 tea. indigo, cacao, and ciuclioiia ; a description of the botanical garden at 

 Buitenzorg; comparative studies between the primeval forests of Brazil and 

 Java ; investigations on the starch and sugar content of tropical and endemic 

 plants; comparative studies of the transpiration of plants in' Java and Jena; 

 and a method of olitaining caoutchouc in Siiiga])ore. 



The influence of climate on plant structures, C. Holtermann (/>(;/• Kiufluss 

 des Klinia-^ aiif den Ban drr Pfianzeiujvicebc Berlin: IF. Einjclniann, 1907. pp. 

 VIII + 2-'i9, plx. 16, fii.ix. 7). — The results are given of extensive anatomical and 

 physiological studies made in the Tropics to determine the effect of tr()i)ical 

 climatic conditions on the structure of plant tissues. Most of the investigations 

 were made in Ceylon and confirmed in Jn\a and elsewhere. Considerable atten- 

 tion is given to the transpiration of tropical plants, especially as influenced by 

 the temperature and moisture relations. The different types of plant associa- 

 tions are described in considerable detail, after which chapters are devoted to 

 the subjects of leaf fall and zonal, or the so-called year-ring, growth in the 

 Tropics. .V number of other interesting i)henomena of plant growth in the 

 Tropics are described, and the work concludes with a cousiderable list of 

 publications relating to the investigations.
