region in Otsego County and vicinity. The results show that 

 a good degree of control of this hop pest is secured by a thorough 

 dusting with sulphur. It now remains for the hop growers to apply 

 the remedy and it is not felt that it is wise to make further expendi- 

 ture of money along this line. Practically no work has been done 

 on the culture of the hop and for that reason a new field has been 

 started on the farm of P. R. Bennett, of Milford, where experiments 

 in methods of culture and fertilization will be carried on. It is felt 

 that by starting a new field the results of the experiments will be 

 more significant than if these experiments are carried on in an old 

 field. 



investigations relative to grape culture. 

 The studies which are being carried on in Chautauqua County, 

 largely in the vineyard rented of Mr. H. B. Benjamin, which will be 

 continued for at least ten years, have already produced fruitful 

 results. Experiments are also being conducted in the control of 

 insect and fungus pests in various places in Chautauqua County, 

 and the outcome of this work is very encouraging. As intimated 

 in my last report, similar work has been taken up in the Keuka Lake 

 region at Urbana. As the experiments in this locality have only 

 been carried on for one year, nothing of any definite character can 

 be said concerning the outcome. 



investigations relative to tobacco culture. 



The fertilizer experiments located with the Minier Brothers at 

 Big Flats have been discontinued and the results will be published 

 at the earliest opportunity. Experimental work is being continued 

 at Baldwinsville in cooperation with the United States Department 

 of Agriculture, Mr. George W. Harris, representing the Department, 

 having the immediate supervision of the work. 



soil investigations. 



The equipment of the Department of Agronomy for reliable 

 investigation of soils has been greatly augmented by the construction 

 of a battery of lysimeter tanks by means of which it will be possible 

 to study certain soil problems in a much more exact manner than 

 could be done in field work. Studies with such an apparatus must 

 be continued for a long time before conclusions are reached.
