Florida station it was as low as in 1906. The Maine station stood 

 second and Connecticut third. In examining figure 4, on which is 

 charted the summary of the analytical data given for the Stowell 

 Evergreen, it will be noticed that Maryland has the highest per- 

 centage of sugar for the Stowell Evergreen and South Carolina for 

 the Crosby, exceeding the figure for Maine by 5 per cent. A com- 

 parison of the data for 1908 with those of the three preceding years 

 shows the sugar content in both varieties to be above those for 1906, 

 but below 1905 and 1907. The average moisture content for the 

 Stowell Evergreen (75.14) is higher than that of the Crosby (72.11). 

 The percentage of sunshine is practically the same for the Florida 

 and the Connecticut stations, with Maryland next and South Carolina

last. Attention should be called to the fact that these data were not 

 obtained at the stations, but at distances varying from 8 miles in the 

 case of the Maryland and Connecticut stations to 30 miles for the 

 Florida station and 100 miles for the South Carolina station. Xo 

 conclusive deductions can be drawn, therefore, but taking into con- 

 sideration also the number of clear, cloudy, and partly cloudy days 

 as given for each station, the data confirm the opinion stated in the 

 summary of the 1905 work, namely, that unobstructed sunshine is 

 not necessary to the development of sugar. 



In figure 4 is shown the percentage of sugar, together with the 

 average length of day, the temperature, and the altitude of the several 

 stations. The average temperature for the growing season was higher 

 at each station for 1908 than it was for 1907 and the South Carolina 

 figures again show the effect of the high altitude.
