embodied in Bulletins Nos. XIV, XV, and XXIV. The im- 

 portance of these published results speak for themselves ; but it 

 should also be borne in mind, as stated in the report of this de- 

 partment for 1889, that in the investigations of plant diseases, a 

 large amount of careful and pains taking work is called for 

 which may not be productive of material suitable for publication 

 in station bulletins. 



In addition to the expenditure of station funds above noted, 

 some expenditures were made at the organization of the station 

 for a microscope, a small amount of chemical and physiological 

 apparatus, and a collection of greenhouse plants, with the ex- 

 pectation that from time to time notes of minor importance 

 might be contributed by the Station in addition to the more im- 

 portant subjects to which its main efforts were to be devoted. 

 No expenditure of this kind, however, for salary or otherwise, 

 has since been made, and although some work has been done or 



is still in progress, no results of sufficient importance for publi- 

 cation have as yet been reached. 



All appropriations of station funds to the department, including 

 the annual appropriations, have been, with the exception above 

 noted, expended in improving and extending the equipment for 

 the study of plant diseases, or for the current expenses in carry- 

 ing on this work, or for the payment in part of Professor Dud- 

 ley's salary. Besides, no charge is made to the station by the 

 department for rent, lights, fuel, for the use of apparatus and 

 collections, nor for the use of the plant-houses for carrying on 

 various experiments involving, to some extent, the labor of the 

 head gardener and his assistants. Further than this, the work of 

 students carried on wholly for the purpose of instruction, is at 

 times of value to the station. For instance, in the experiments 

 on the strawberry leaf blight, the results of which are given in 

 Bulletin XIV, one of the most important facts, from a scientific 

 point of view, there recorded, was brought out by a special stu- 

 dent in the course of a study of the life history of the fungus 

 causing the disease. From this it will be seen that the department 

 has made large contributions to the station in the way of facili- 

 ties for carrying on its special work ; in turn the department has 

 received some added strength in certain lines from the station ; 

 but it is obvious that the former out weigh the latter in large pro- 

 portion. Experience will no doubt suggest changes and improve- 

 ments ; but there seems to be no reason why the department and 

 station may not work together to their mutual advantage. 



A more complete statement in regard to the work on plant 

 diseases, its nature, methods, progress, and present condition, 

 prepared by Professor Dudley, accompanies this report.
