accumulated by careful painstaking and critical work that 

 the heterogeneous mass of information can be reduced to 

 anything like order. 



For several years the Division of Vegetable Pathology of 

 the Department of Agriculture has had in view a thorough 

 investigation of the citrous fruits of Florida. A number of 

 efforts have been made to start investigations that would at 

 least throw light on ^some of the troublesome diseases, but 



plished. Recently, however, a moreliberT^lppropriaSon 

 has enabled the Division to undertake a series of investiga- 

 tions which, it is hoped, will solve many of the questions now 

 being asked by intelligent orange growers. A sub-tropical 

 laboratory has been established at Eustis, in the heart of the 

 orange region. The laboratory building, erected by the citi- 

 zens of the town, is being fitted up with apparatus of the 

 most modern type for physiological, anatomical and patho- 

 logical research. A library on citrous fruits, containing 

 works from all parts of the world, has been added, making 

 the equipment, for the present needs at least, fairly complete. 

 The work at first will be mainly upon the diseases of citrous 

 truits, but it is not proposed by any means to limit the in- 

 vestigations to this field. As the very foundation upon which 

 all subsequent work will rest, a thorough study of the normal 

 physiology and anatomy of citrous and allied fruits must be 

 made. The most troublesome diseases are, in all probabil- 

 ity due to causes which the foregoing studies alone can re- 

 veal, diseases due to parasitic organisms are among the 

 earliest to study, but even here the physiology and anatomy 

 of the plant must be known before a thorough understanding 

 of all phases of the subject can be reached. Besides aiding 

 m the investigations set forth in the foregoing, the physiolog- 

 ical and other studies will throw light upon questions of the 

 highest importance m a practical sense. Every intelligent
