A series of photographs showing graphically the size and vigor of the 

 alfalfa plants and the abundance of weeds on the various plats was made, 

 but as the same teachings are brought out in illustrations of 1905 seeding 

 to be considered later, it is thought best not to take space for these 

 pictures here. 



The winter of 1904-1905 was about normal at Ithaca and there was 

 no unusual damage to alfalfa. On June 9, 1905, the following observa- 

 tions as to the general condition of the various plats of the 1004 seeding 

 were made : 



Plat No. 741. Check, no treatment. 



Plants light in color, small and not thick, many small weeds, ground 

 covered with small grass.
