REPORT OF THH CHEMIST. 



To tlie Director of the Cornell University Agrtmiltural Exper't- 

 iiient Station : 



Sir. — Nearly all of the work ot the Chemical Division of the 

 Federal Experiment Station for the year 1900-1901 has been done 

 by the Assistant Chemist, Mr. G. W. Cavanaiigh. The report is, 

 therefore, made and signed by him. 



Yery respectfully yours, 



G. C. CALDWELL. 



To the Chemist of the Cornell University Agricultural Experi- 

 ment Station : 



Sir. — The following is a general account of the chemical 

 analyses and the investigations which have been made during the 

 past year. 



One hundred and sixty-six samples of sugar beets have been 

 analyzed and various by-products of the sugar factories have been 

 examined. Special attention was given to the study of the quality of 

 certain standard varieties. Analyses of twenty-six samples of soils 

 with reference to the conservation of soil moisture have been made. 



In response to. mmit^i'ous requests analyses of worn-out soils have 

 been undertaken. AYliile it is not expected that an analysis will of 

 itself always show the means of restoring the fertility of such soils, 

 it is believed that the results, if properly studied, may, in many 

 cases, be very useful. 



There has been an increased demand from different parts of the 

 State for the examination of aa'ricultural materials of more or less 

 value. Under this head may be included thirty-six samples of fer- 

 tilizers, feeds, soils, ashes, butter colors and insecticides. 



Four cases have been submitted from the Yeterinary College for 

 toxicological examination, and have been analyzed. 



Respectfully submitted, 



G. W. CAYANAUGH.
