(9) Studies on soil stiiicture. 



(10) Establishiug methods of stiulyiug and determining the col- 

 loid^s in soils. 



(11) Study on the activity of soils. 



Preliminary or final reports have already been prepared for the first 

 five problems and are being- ])nl)lislied as scientific articles in Soils 

 Science and in the Journal of Agi-icultural Research. The investigation 

 of the other six problems is being continued." 



On the basis of these results and general conditions in the State I 

 maintain that the financial support of soil investigations is woefully 

 deficient. The expenditures for this Section, aside from salaries, 

 since it was reorganized in 1911, as funiLslied by J. Schepers, Treasurer, 

 are as follow® :
