effect of leguminous and nonlegnminous crops on Houston clay soil, 

 and the use of fertilizers on black bottom and poor red land and in 

 connection with continuous cotton culture. In cotton variety tests 

 yields and values per acre were determined on Houston clay of 

 medium fertility and on upland soil of the Canebrake region. Con- 

 siderable attention was given to the residual effect of the various 

 methods of soil treatment. 



The experiments in general showed that the use of nitrogenous 

 manures gave the best results on the soils of the canebrake, and that 

 nitrogen was supplied most economically by alfalfa residues. AVith 

 these results in view the station recommended rotations in which 

 alfalfa alternates Avith harrowed crops. 



Bulletin 27, Agricultural Value of Nitrogenous Materials for Cot- 

 ton on the Houston Clays as Determined by Field Trials, Residual 

 Effect of Cover Crops, Alfalfa Yields, and Effect as a Means of 

 Restoring Fertility, was received by this office during the year. 



The income of the station during the past fiscal year was as follows :

The purpose of the Canebrake station is the solution of problems 

 connected with the agriculture of a particular region of the State, 

 and for this reason the institution takes up primarily questions which 

 have a direct and immediate ))earing upon the existing farm practices 

 and conditions in the Canebrake region.

The Tuskegee station devoted considerable time during the year 

 to the study of ornamental plants and possibilities of sweet-potato 

 culture, and the development of nature study and gardening for 

 rural schools. A bulletin was published on evergreens and decidu- 

 ous trees and shrubs, vines, ferns, and other pond, marsh, and bog 

 plants and other miscellaneous species found in Macon County, 

 Ala., and adapted to ornamental planting and landscape gardening 

 in general. 



In connection with sweet-potato culture the station studied seed 

 selection, soil preparation, methods of culture and fertilization, har- 

 vesting and storing, and various insect enemies and plant diseases 

 attacking the crop. In feeding experiments sweet potatoes were fed 

 to horses, mules, and hogs. The station further gave particular 

 attention to the establishment and manner of conductino- nature 

 study and school-garden work, and gave numerous suggestions with 

 reference to the location and preparation of land for school-garden
