Hoerning's Improved Kleinwanzlebener seed was received from Ed- 

 mund Stark, Grand Island, Neb., and was sown on Plot 12, the acre 

 east of Plot 11 and adjacent to it. The seed arrived late and was sown 

 May 18 and 22. 



The Floto's Improved Beet seed was donated to the Station by the Wer- 

 Dich Seed Co., Milwaukee, Wis., arrived late, and was sown May 22, in 

 rows parallel to the acre plots and east of them 12 rods. 



Experiments were planned to test the relative values of commercial 

 fertilizers and of certain mineral salts on the growth of sugar beets, 

 but the crop was so badly injured by a fungus disease (Cercospora beti- 

 cola) as to invalidate the results. The addition of mineral manures did 

 in general increase the yield, but accurate results cannot be given 

 because of the invasion of this disease. 



REPORTS OF EXPERIMENTS MADE BY FARMERS AND RESULTS OF ANALYSES 



OF THE SUGAR BEETS. 



On the receipt of notice from the Department at Washington that 

 sugar beet seed was to be sent to the station for distribution, letters 

 were written to a large number of farmers, several in nearly all of the 

 counties of the lower peninsula, explaining the nature of the proposed 

 experiments and asking cooperation in the solution of the questions 

 relating to the quantity and quality of sugar beets that Michigan could 

 produce. Four hundred and sixty-six separate shipments of seed were 

 made. A single shipment went often to several farmers, there being 

 the names of four hundred and eighty-nine farmers on the list of those 

 who received seed from the Station. To several places, notably Saginaw, 

 Port Huron, Sand Beach, and a few others, amounts of seed were sent in 

 bulk and distributed by persons appointed for that purpose by the Sta- 

 tion. 



From time to time during the season special bulletins were issued and 

 sent to the beet growers outlining the correct methods of planting, caring 

 for and harvesting the crop. By private letters, by special publications 

 and by articles in the newspapers, the officers of the Station called atten-
