EDITORIAL. 603 



Grandean had realized from the first that an experiment station 

 needed not only a laboratory, but also experimental fields. His field 

 work was conducted at the outset in part upon his own estate, and 

 when the Mathieu de Dombasle School of Agriculture was estab- 

 lished at Tomblaine near Nancy, he saw to it that such fields were 

 provided. Here he carried on his cultural and fertilizer experiments 

 for years, and when the station was transferred to the vicinity of 

 Paris in 1890, he secured land for his field work at the Pare des 

 Princes, in the immediate vicinity of the city. 



Grandeau conducted an active campaign for the establishment of 

 similar stations in various parts of the Kepublic. and was a large fac- 

 tor in this movement. In 1881 he was appointed inspector general of 

 the stations, a position he held until the close of his life, which gave 

 him a wider opportunity for the exercise of his influence. He estab- 

 lished the Annates de la Science Agronomique, which was published 

 under the auspices of the Ministry of Agriculture, as an organ of the 

 agricultural stations and laboratories of France, for the dissemina- 

 tion of their detailed work, and for bringing to their notice the work 

 of stations in other countries. He remained in active editorial man- 

 agement of this journal nearly to the close of his career. 



Grandeau was an earnest advocate of the demonstration fields, 

 which early became a feature of the campaign for the improvement 

 of agriculture, and urged their establishment and extension through- 

 out the Republic. These fields, of which there are more than three 

 thousand, were designed to bring the results and applications of the 

 teachings of the stations to the attention of farmers by ocular demon- 

 strations on small areas. On one occasion he said in advocating 

 them : " If every town of France could have a demonstration field, 

 the agricultural aspect of the country would be changed in a few 

 years and the primary benefit to the peasant would redound to the 

 benefit of the country as a whole." These fields are ranked among the 

 most powerful agencies for increasing and improving agricultural 

 production in that country. 



In 1872 one of the omnibus companies of Paris decided to establish 

 a laboratory for the purpose of carrying on experimental work with 

 reference to the rational feeding of horses, and Grandeau was in- 

 trusted with the task of organizing this laboratory and directing its 

 Avork. His activities in that direction continued through many years, 

 and led to a wider interest in both human and animal nutrition, to 

 which subjects he gave much attention during the last years of his 

 life. In 1905 he summarized the results of twenty years' investiga- 

 tion with work horses, giving practical deductions as well as theoreti- 

 cal conclusions. 



As a teacher Grandeau's influence was exerted both in the class- 

 room and through the press. At the age of twenty-five he was pro-
