(5) Per cent of sugar was affected by second growth in October or by absorbing 

 moisture from the rains after long drouth, or both. 



(6) Yield per acre has much to do with the profitableness of the crop ; and 



(7) While our highest analysis came from beets averaging 13 ounces, trimmed, and 

 yielding 12.32 tons per acre, our largest yield of sugar per acre came from beets 

 averaging 21 ounces, trimmed, and yielding 28.163 tons per acre. 



(8) Clay soil gave us the highest per cent of sugar and comparatively higher purity 

 and the lowest tonnage per acre. 



(9) Three plats fertilized with lime, nitrogen, phosphoric acid, and potash, gave 110 

 evident benefit. 



(10) The average per cent of sugar was 14.14, and the average yield about 20 tons 

 an acre, and the cost of growing and harvesting $39.42 an acre. The highest sugar 

 in beets, per acre, was 7.299 pounds. 



The foregoing comments on the work were taken from the bulletin of 

 the station No. 15. From the same bulletin, also, the following extracts 

 are taken, relating to the experiments made by the farmers in the dif- 

 ferent parts of the State of Iowa. 



In all 502 samples were received, and fifty-one counties were repre- 

 sented. The average percentages of sugar in the beets as analyzed at 

 the Iowa Experiment Station laboratory, were as follows : 



On account of the large number of samples received from Muscatine 

 County the analyses are divided into three groups. The first group 

 contained 53 samples and had a mean percentage of sugar in the beet 

 of 1.1.96. The second group contained 61 samples and had a mean per- 

 centage of sugar in the beet of 12.29. The third group contained 96 

 samples and contained a mean percentage of 13.64 of sugar in the beet. 

 This is also a remarkable showing, and corresponds with the results 

 obtained on the beets from this county analyzed in the laboratory of 

 the Department of Agriculture, where 31 samples showed an average 

 of 14.11 per cent of sugar. Certainly no further evidence than this 

 will be needed to convince anyone that the county of Muscatine, in Iowa,
