b. The economy of using soluble and insoluble phosphates 

 on the basis of an equal money value per acre for the produc- 

 tion of farm crops. (Field F, serradella. ) 



c. The influence of different forms of nitrogen and of 

 potash on the quality and quantity of farm and garden crops. 



d. The relation of the composition of plants to plant 

 diseases. (Vegetation house.) 



2. Among general farm crops, forage crops, in particu- 

 lar annual leguminous forage crops, have received special 

 attention. Among them are some reputed forage crops new 

 to our section of the country. To test their degree of adap- 

 tation to our climate and soil, as well as their o-eneral eco- 

 nomical value under our market condition of fodder articles, 

 has been our aim : summer vetch and oats, Canada peas and 

 oats, several varieties of soja bean, serradella. Southern cow- 

 pea. 



Some of these have been fed as green fodder, or as hay, 

 or as ensilage, or in all three forms, as a rule with much 

 satisfaction. 



There are several silos, filled with mixed forage crops, on 

 hand, viz., soja bean and fodder corn, serradella with Hun- 

 garian grass. 



The field experiments are in several instances accompanied 

 with observations in the vegetation house. 



Our meadows are top-dressed either with barn-yard ma- 

 nure or bone and muriate of potash, or wood ashes. 



III. On the Work in the Chejiical Laboratory of 



THE Station (1892). 



The Avork performed in the chemical laboratory is quite 

 extensive and in various directions, and is steadily increas- 

 ing. The analyses arising in connection with investigations 

 carried on in the vegetation house, the field and the barn of 

 the station, are quite numerous. The analyses of fertilizers, 

 fodder articles, well water, etc., made at the request of 

 farmers and farmers' clubs, are of daily occurrence. Aside 

 from these current sources of work, nmch responsible work 

 has to be carried on in the line of the official analyses of 

 commercial fertilizers and of imitations of butter.
