TIVEXTIETH ANNUAL MEETING. 83 



are looking forward, that the horticultural experiments are 

 tending toward the idea that it is the sulphur itself which is 

 the real germicide. It has been stated that it is not the lime 

 in the lime-sulphur, but the sulphur. 



Prof. \A'hetzel has referred to some interesting" photographs 

 that he saw of a V'irginia orchard, in which a particular type 

 or substance, not exactly lime-sulphur, but something like it, 

 was made use of. Here it is, (showing a tube of liquid) 

 this is a new fungicide entirely different from anytliing which 

 has been produced before. It is going to be put on the 

 market, and it is made from a scientific study of the matter. 

 Here is some of the most evenly divided sulphur which is on 

 the market and it won't precipitate. I mixed this sample up 

 with water before the afternoon session began, and you see 

 it has all settled ; you can stir it up, but it is not in suspension. 

 Here is another batch of sulphur which has been prepared by 

 a special new process which was mixed just before the other 

 one. That has been shaken up and l^s been standing for 

 some time. Here, you see, is elementary sulphur, practicall}' 

 that, nothing else except it is prepared by a process which 

 keeps it in suspension. It is extremely evenly divided and 

 ready to use as a spray. There is a little sediment, but that 

 can be stirred up and sprayed on with it. You see the fine 

 division of the material enables you to cover a vast surface, 

 and it is so evenly divided that it is very active, and it can be 

 prepared very cheaply, and I am going to speak of that. I 

 hope you will be able to get it. It comes in the form of a 

 paste and can be mixed up just as you mix up arsenate of 

 lead. And speaking of arsenate of lead, this has been mixed 

 with arsenate of lead, and you can get both your insecticide 

 and fungicide right together. It has been used on potatoes, 

 and peaches, and at least 100 different experiments have 

 been made by the most conservative experiment station 

 people, and the owner of the. orchard which was referred to 

 here, ]\Ir. Gold Miller of West Virginia, has made experi- 

 ments and writes me a letter like this: "If I had known
