ing may be expected to succeed in our Southern States. Special 

 attention will also be given to the problem of Phjdloxera-resistant 

 stocks for the Pacific coast and to direct jjroducers suited to Eastern 

 grape districts. 



The mapping of fruit districts will be based at the outset upon the 

 recorded experience of growers, reinforced and corrected by careful 

 field investigation by experts, and shaped so far as possible to con-' 

 form to the tojjographic and geologic map work already done by the 

 United States Geological Survej^ and the soil maps now being pre- 

 pared by the Bureau of Soils of this DeiJartment. 



EXPERIMENTAL GARDENS AND GROUNDS. 

 WORK OF THE YEAE. 



The work has been directed during most of the year by the chief of 

 the Bureau, but recently the details have been put in charge of Mr. 

 L. C. Corbett, horticulturist of the Department. Mr. Corbett submits 

 the report, setting forth the progress of the work of this bi-anch. 



The general scheme of work outlined in the last annual report by 

 the Director of Plant Industry has been put into effect, and the close 

 cooperation of this branch with that of Plant Physiology and Pathol- 

 ogy, Agrostology-, Pomology, Botany, and Seed and Plant Introduction 

 has become a reality.

Much time has been devoted to the jiruning of shrubs and trees 

 about the grounds. The growth of others has made the removal of 

 some specimens necessary in order to preserve those of most value. 

 In all cases, when tlie futtire preservation of rare and valuable speci- 

 mens has been involved, such crowding trees have been removed.
