em California, which is the last of the great fruit areas in southern 

 California that remains to be survej'ed. It is believed that very val- 

 uable results will be attained by the soil survey when it is extended 

 to the sugar-beet area around Chino and the fruit areas of Pomona, 

 Riverside, San Bernardino, and neighboring towns. 



In all it appears desirable to spend twenty-one months, on the basis 

 of one party, in the State of California during the next field season, 

 and it is believed that the importance of the areas to be investigated 

 fully justifies the time and attention to be given to the work. 



COLORADO. 



During the present field season a soil survey is being made, under 

 the charge of Mr. Mac}^ H. Lapham, of the irrigable lands of the 

 Arkansas Valley between Rockyford and the Kansas State line. 

 There will be nearly 1,000 square miles of intricate soil mapping, with 

 alkali problems to be worked out, but it is believed that by concentrat- 

 ing some of the northern jjarties in this area during the fall the 

 whole area can be survej^ed. This work is undertaken jirincipally in 

 the interest of the sugar-beet growers and of the melon and truck 

 growers. Not only is it desirable to understand better the relation 

 of the soils to crops, but with the extension of irrigation systems the 

 natural drainage is found to be deficient and alkali is rising and 

 threatening trouble and losses. The work has progressed far enough 

 to indicate that the alkali problem can be economically and efficiently 

 controlled, and it is believed that the classification of the soils will 

 give a basis for the most profitable development of the sugar-beet and 

 truck interests of tlie area. 



It appears desirable to spend about six months during the next field 

 season in a survey of the San Luis Valley, where the alkali problem 

 is becoming far more serious even than in the Arkansas Valley. 



CONNECTICUT. 



No extension of the soil survey has been made in the Connecticut 

 Valley since 1899, but with the extension of the profitable industry of 

 producing the shade-grown Sumatra tobacco there is a very strong 

 demand now that the survey should be extended to include many 

 smaller valleys on either side of the area surveyed in 1899, and it is 

 proposed to spend about three months in the State during the next 

 field season, to give a basis for the extension of the tobacco industry 

 on either side of the main valley. 



DELAWARE. 



No survej^s have been made as yet in Delaware, and none are con- 

 templated during the present j^ear. There is, however, a demand for a 

 soil survey to extend over the entire State, and it seems desirable to 

 spend three months in the State during the next fiscal year in such 

 work. 



FLORIDA. 



No surveys have been made in this State up to the present time, but 

 it is proposed, if suitable arrangements can be made for a base map, 

 to make a soil survey in Gadsen County in the interest of the tobacco 

 growers. 



GEORGIA. 



During the past fiscal year two areas were surveyed in Georgia, 

 including Cobb County and an area around Covington, the former
