The soil data represent the averages of figures for soil and subsoil. The geodetic 

 data, except for Laramie, Wyo., and Union, Oreg., have been previously given. 

 The altitude of Laramie is 7,130.5 and that of Union 2,689.6 ft, 



The results again indicate that the content of sugar rises as the latitude increases. 

 An intimate relation between the percentage of sugar in the beet and the length of 

 day is also indicated. The figures likewise show that, "as a rule the temperature 

 varies inversely as the sugar content, being highest when sugar is lowest," and vice 

 versa. The percentage of sugar in the beet and the altitude show a general agree- 

 ment, although this is not uniform, and it is concluded that the only effect of altitude 

 is due to a decrease in temperature. The distribution of rainfall appears to have 

 had no direct effect upon the content of sugar, although it is stated that there might 

 be such a distribution as to influence the quality of the beet unfavorably. The data 

 for the year are considered less decisive and less complete than for the previous 

 seasons. 



[Cooperative tests with sugar beets and alfalfa], V. K. Chesnut (Montana 

 Sta. Bpt. 1904, pp- 233-235). — About 50 lbs. of Klein wanzlebener beet seed produced 

 in the State of Washington, and secured by this Department, was distributed in 

 Montana and the beets raised were tested. 



The richest lot contained 22.8 per cent of sugar. The largest estimated yield of 

 sugar per acre, 5,825 lbs., was obtained on the station farm. Vilmorin Imperial, 

 French Red Top, and Utah sugar beets grown in comparison with this seed were 

 inferior in every particular with the exception that the LTtah-grown seed showed a 

 purity 1.08 per cent greater than the Klein wanzlebener. The average of 22 beets 

 grown in various parts of the State from the seed distributed by the station con- 

 tained 16.9 per cent of sugar with 82.73 per cent purity. 



Experiments in inoculating alfalfa seed with cultures obtained from this Depart- 

 ment indicated that the treatment produced more vigorous seedlings. Reports on 

 the individual tests have not yet been made. 



Experiments in the culture of sugar cane and its manufacture into table 

 sirup, H. W. Wiley et al. ( V. S. Bept. Agr., Bur. ('hem. Bui. .93, pp. 78, pis. 5, 

 figs. 6). — This bulletin is a report on investigations conducted at Waycross and 

 Cairo, Ga., in 1903 and 1904, in continuation of previous work (E. S. R., 15, p. 245). 



In 1903 experiments were conducted at Cairo on 2 fields, both old and sandy land. 

 Fertilizers were applied in different quantities and combinations, either in the fur- 

 row or broadcast. On some plats the entire application was made at one time, while 

 on others 2 or 3 partial applications were made at different times. In some cases 

 the cane was planted on top of the fertilizer, which had been applied in the furrow. 

 The season was unfavorable and the stand was poor.
