No. 4.] FUNGOUS DISEASES. 109 



close to recognized things. Some of the stations make a 

 busine^ss of analyzing a good many things put on the market. 

 Cornell has done a great deal of it. We have done very 

 little except with Paris green. Every year there are things 

 sent to us that will cure all diseases of plants. We have not 

 the time or money to give them the test that they ought to 

 have, to decide if they are of value. After all, the farmer 

 must test these things for himself. He must have a little 

 experiment station on his own farm. 



Question. What is the cause of the Sheldon pear crack- 

 ing when about half grown, and turning dark colored? 



Dr. Stuugis. It is a fungus very nearly related to the 

 apple scab. It can be controlled in the same way by spray- 

 ing. I know of no other way. 



Mr. C. H. Parker (of Holden). I want to express my 

 satisfaction with the lecture. I think it about time for the 

 farmers, even if they grow a small acreage of potatoes, to 

 adopt some of these methods. I heard it said that the pro- 

 gressive farmer sprayed his potatoes. Now, there are a good 

 many in my town who are not progressive, that I really 

 supposed were fairly up in the line of progress. I had five 

 acres this last year, and the crop was an absolute fiiilure, for 

 the blight struck the potatoes before they were half grown, 

 and it hardly paid to dig them. I shall either spray my 

 potatoes in the future, or cease to plant them. 



The Chairman. The time has been fully occupied, and 

 we will have to postpone Professor Maynard's talk on apples 

 until after the afternoon lecture. 



Adjourned to 2 o'clock. 



Afternoon Session. 

 The meeting was called to order at 2 o'clock by Second 

 Vice-President Pratt, who said : We have for our consider- 

 ation this afternoon a very important; subject, — the subject 

 of ventilation. The lecturer is a graduate of the Massachu- 

 setts Agricultural College and the professor of veterinary 

 science at that institution, and is thoroughly acquainted with 

 his subject. I take pleasure in introducing Dr. Paige, who 

 "will speak on " Stable ventilation."
