WORKS ON 



TROPICAL AGRICULTURE 



PRINCIPLES OF AUSTRALIAN AGRICUL- 

 TURE. By W. CATTON GRASBV. Illustrated. 

 Crown 8vo. 43. 6d. 



In 1892 the Minister for Education and Agriculture in South 

 Australia convened a conference to discuss the best means for 

 promoting agricultural education. Among the recommendations 

 adopted was one affirming the necessity for a text-book on Australian 

 agriculture. For twenty years nobody was found to undertake the 

 task ; then at length Mr. Grasby stepped into the breach. In the 

 preparation of his book he has been guided by the standard works 

 on soils, fertilisers, and principles of agriculture, and by his own 

 experience and that of many farmers with whom he has come in 

 contact in the course of his work as lecturer and agricultural writer. 



TEXT-BOOK OF TROPICAL AGRICULTURE. 



By H. A. A. NiCHOLLS, M.D., F.L.S. Illustrated. 

 Crown 8vo. 6s. 



This general treatise upon agriculture in the Tropics has become 

 a standard handbook for the planter in hot countries. It conveys 

 strictly scientific information in readable form and abounds in 

 illustrations. 



DRY-FARMING. A System of Agriculture for Countries 

 under a Low Rainfall. By JOHN A. WlDTSOE, Ph.D. 

 Illustrated. Crown Svo. 6s. 6d. net 



Professor Widtsoe's book is an attempt to assemble and organise 

 the known facts of science in their relations to the profitable pro- 

 duction of plants without irrigation in regions of limited rainfall. 

 The needs of the actual farmer, who must understand the principles 

 before his practice can be wholly satisfactory, have been kept in 

 view primarily, but it is believed that the enlarging group of dry 

 farm investigators will also be materially helped by this clear 

 presentation of the subject.
