700 EXPERIMENT STATION RECORD. 



associates were of the greatest importance as contri})utions on the fundamental laws 

 of nutrition and bearing on the details of practical feeding. His labors as a teacher 

 continued until 1894, shortly after the semicentennial of liis doctorate was celebrated. 

 At this time his colleagues and scientists in institutions in other countries united to 

 do him honor. It is difficult to overestimate the influence which a man of Petten- 

 kofer's stamp exercises upon students in a half century of active work. 



Martin Ewald Wollny, the distinguished agricultural investigator, died at Munich 

 January 8, 1901. He was born at Berlin, March 20, 1846. His studies at the Agri- 

 cultural Academy of Proskau and the universities of Halle and Lt'nsic were inter- 

 spersed with several years of practical experience on farms, and he received the 

 degree of doctor of philosophy from the latter university in 1870. In 1871 he was 

 made professor of agriculture in the Agricultural Academy of Proskau, where he 

 remained 3 J years, being called thence to the professorship of agriculture in the 

 agricultural department of the Munich Technical High School, where he remained 

 until his death. Professor "Wollny was one of the first and most prominent of inves- 

 tigators to clearly recognize the importance of the physical properties of soils — mois- 

 ture, temperature, aeration — in the production of plants, and for 20 j-ears the journal, 

 Forschungen auf dem Gebiete der AgrikiilturpJiym/c, founded by him, was largely filled 

 with accounts of the researches which he made in this field. He was a prolific 

 writer and contributed extensively to other journals, several of his resumes appearing 

 in the Record. He was also the author of a large number of books and pamphlets, 

 of which the following are the more important: Dei- Einfluss der Pflanzendecke und 

 Beschatiung auf die pliysikallschen Eigenschaften und die Fmchtbarkeit des Bodens (1877) , 

 Ueber die Anwendung der Elektrizitdt bei der PflanzenkuUur (1883), Ueber die Thdtigkeit 

 niederer Organismen im Boden (1883), Sttat und Pjiege der landw. Kulturpjfanzen (1885), 

 Die Krliur der Getreidearten (1887), Welrhe MuorgaUungen eignen sich far die Aniegung 

 von liimpauschen DammkidMrenf (1890), and Zersetzung der organischen Stoffe und die 

 IIu in usbiJdungen (1897 ) . 



Prof. F. H. Werenskiold, director of the agricultural-chemical control station at 

 Christiania, and a quite prominent contributor to the literature of agricultural inves- 

 tigations in Norway, died suddenly November 13, 1900, at the age of 49 years. 



Miscellaneous. — The agricultural council of the Russian Ministry of Agriculture 

 and Imperial Estates has taken steps in the direction of improving tlie character of 

 the live stock and the live-stock industry in general of that country. At present 

 this industry is said to be far liehind that of other countries, the animals kept l>eing 

 inferior and stock raising receiving comparatively small attention from the fanners. 

 The council has recommended the holding of live-stock shows, with prizes for 

 excellence, the establishment of breeding farms and furnishing of expert assistance 

 in purchasing good breeding animals, the maintenance of local breeding establish- 

 ments where the service of pure-bred animals can l)e secured, and loans to munici- 

 palities and societies for the purpose of purchasing pure-bred animals and providing 

 for their care. In order to carry out the above measures the Ministry of Agriculture, 

 with the concurrence of the Minister of Finance, has recommended an appropriation 

 of 5,000,000 rubles (about $2,000,000) to begin this work and a quadrennial appro- 

 I)riation of 1,125,000 rubles. 



Science reports that an anonymous gift of £50,000 has been made to the Woman's 

 Agricultural College at Reading, f^ngland. 



Prof. T. Pfeiffer, director of the agricultural-chemical laboratory of the University 

 of Jena, has been called to Breslau to succeed Prof. A. Stutzer, who has gone to 

 Konigsberg. Professor Pfeiffer is succeeded at Jena by Dr. Immenhoff, for several 

 years first assistant at the Moor Experiment Station at Bremen.
