46 Agronomy. 



The following table shows the character of the co-operative ex- 

 periments and the number of experiments arranged by Professor 

 Stone during 1906: 



Alfalfa 75 



Oats 45 



Fertilizers 11 



Potatoes 157 



Potato cultures 6 



Sunflowers 14 



Soy beans and other legumes 30 



Beans 34 



Buckwheat 16 



Vetch 7 



Weeds 66 



Lime 8 



Meadows 16 



Dwarf milo 13 



Millet 10 



Total 508 



About 300 different persons located in 55 dififerent counties co- 

 operated in these experiments. 



Two important objects in the co-operative experiments have beefi 

 ( I ) to gain information in regard to the soil and crops under experi- 

 ment, and (2) to extend the educational influence of the experiments 

 to the farmers who are doing the work or to their neighbors who 

 observe them. Heretofore the second of these objects has received 

 the greatest emphasis. It is now believed that the time has come 

 Avhen more emphasis should be placed upon the research rather than 

 the educational aspect of the work. This does not mean that a less 

 number of experiments of the ordinary co-operative type should be 

 conducted, but that mo*re experiments should be conducted in dififer- 

 ent parts of the State which are directly under the supervision of 

 the College of Agriculture. Many problems will require a thorough 

 investigation which cannot be caried out here at the Experiment 

 Station because of local conditions. Tn making up the list of sug- 

 gested experiments for the coming year, Dr. Warren has divided 

 them into two categofies, viz., investigations and co-operative experi- 

 ments. The list of experiments to be conducted under each head is 

 given below. 



A. Investigations : 



1. A study in the growth of clovers and alfalfa on volusia loam. 



2. The influence of fertilizers and manure orj the economic 



production of timothy h3y.
