FARM VEHICLES 



In tlie trials with farm vehicles there were made use of a four- 

 inch tire farm wagon, a two-horse farm cart, a farmers' handy 

 wagon, and a pair of bobsleds. The test was one whose j^rimary 

 object was to determine the comparative draft of these vehicles 

 under varying conditions. As a result of such a trial much infor- 

 mation could be obtained in the matter of comparison between 

 broad and medium tired wasons. Also some data concerninp- 

 sliding and rolling friction as affecting the draft of farm imple- 

 ments and vehicles could be gathered. It might also be jDointed. 

 out that a trial of this nature has much to do with showing the 

 relative advantage of loading near the source of power rather 

 than at a distance, and also as to the matter of placing the load 

 on the line of draft or above or below it. The following table is 

 a summary of the work along this line done at this station :

DEPARTMENT OF ENTOMOLOGY 



The work of this department during the year has continued 

 along the lines of previous years, although it was seriously inter- 

 rupted by the lack of an assistant during the important months of 

 April, May, and June. In March Mr. W. F. Fiske, who has ren- 

 dered, efficient assistance for several years, resigned to become 

 assistant state entomologist of Georgia, and his successor, Mr.
