FOURTEENTH ANNUAL MEETING. 163 



ments are the most effective and special emphasis is hereby 

 given to this point. 



To the fruit growers who contemplate using the K-L 

 mixtures let me say, make them according to directions, spray 

 thoroughly, and give them a fair trial. If at any time you 

 wish more information regarding them, please write to me 

 and your requests will receive immediate attention. 



DISCUSSION. 



The President: Mr. Close, you refer to that fifteen per 

 cent. K-L. There is one point about that I do not under- 

 stand. How much is that diluted? 



Prof. Close: Well, that, of course, depends upon the per 

 cent. Here is the limoid, and, by the way, you will see sam- 

 ples of this in the Exhibition Hall below, and Mr. Watkins, 

 who is the agent of the Charles Warner Company, the manu- 

 facturers, and through his kindness we will be able to make 

 some of these mixtures, if you care to oversee them made. 

 This is limoid that I refer to. This is the same that the 

 limoid is made from. In this bottle there is a sample of the 

 dry slacked high calcium lime ; that is, it is made of lime air 

 slacked and high calcium lime. 



In this bottle is a sample of the twenty per cent. K-L mix- 

 ture, and in this other one that I now have in my hand we 

 have the ordinary Bordeaux mixture. Now, when we use the 

 Bordeaux mixture in making K-L-B, we have this material. 

 This is the sample, and you can see the difference in color. 

 The different solutions can usually be detected by the differ- 

 ence in color, so that if you are familiar with them they are 

 readily detected one from the other. This next one, which 

 I will pass around with the rest and ask you to examine so 

 that all may see them, contains a sample of the twenty per 

 cent. K-L, made with dry slacked magnesium lime, and here 

 we have the twenty per cent, mixture made with air slacked 

 lime. 



A Member: Prof. Close, how do you account for the dis- 

 crepancy which seems to exist between the results obtained 

 with the fifteen per cent, solution and the twenty per cent, 

 mixture?
