 At tlie ordinary \alues of these crops there has been an averajj^e money

 mcdons. Then* has been an average ])rofit on all crops of $14, despite 

 the fact that nearly sutiicient moist ui'(» fell in lixio for tli(> needs of 

 the growing crops."' At Audubon J*ai'U, on the other hand, with 

 heavier I'ainfall and more compact soils, the a\'ei-age for a series of 

 years in favor of iiiigation has been small, and in many cases irriga- 

 tion has been injurious. 



The veterinarian is continuing investigations on stomach worms, a 

 nodular disease of the intestines of she(>p, and Texas fever, lie is 

 testing a system In' which he hopes to be able to rear healthy lambs 

 from dams ati'ected with stomach worms or the nodular disease. In all 

 this work he has the etfective coopei-ation of the entomologist. The 

 hitter, from a studj' of the life history and hal)its of the cattle tick, is 

 working out a s^'stem of rotation of fields for tick-infested cattle, which 

 promises an etfective means of ridding cattle of ticks and controlling 

 the disease. He is also cooperating with the Division of Entomology of 

 this Department in studying horseflies, the Mexican cotton-boll weevil, 

 and mos(iuitoes. The stations are also cooperating with the Bureau of 

 Soils in a soil survey. The geological survey, wdth a State ai)propria- 

 tion of $5,000, has been continued. The director is preparing a State 

 exhi])it for the Louisiana Purchase Exposition, for which an appropria- 

 tion of $100, (»()(» has been made. The new library, provi(U>d for by 

 private bequest, and the dormitor}' and mechanical arts buildings, for 

 which the State legislature made appropriations, are approaching com- 

 pletion. 



The Louisiana stations continue to exert a strong influence for the 

 improvement of agricultural practice in the State. The work of the 

 veterinarian in imnnuiizing "cattle against T(»xas fever is doing much 

 to encourage the introduction of improved beef and dairy animals. 

 The opportunity for development along these lines is large, as the 

 stations have shown that a))undant forage is easily produced, and the 

 by-products of the cotton, rice, and sugar industries furnish a large 

 amount of cheap concentrated feed. The work with forage plants has 

 been very comprehensive and successful and has met with so much 

 favor that there has been a large demand for bulletins on this subject. 

 As in former years, considerable attention has been given by mem-
