best results. All of this brings us to the fact that probably 

 intelligent men were behind the use of these things. Xow. for 

 my own part, I wouldn't send my man out with the very best 

 of mechanical pumps, those made for the mixing of kerosene 

 and water, and the reasons are, that the first thing I know, 

 if I send a man out with a mixture to spray trees he will prob- 

 ably spray the first row of trees with water, and the next with 

 kerosene. Those mechanical pumps are not yet so perfected 

 that they will positively and surely give us the mixture we ask 

 for, and I know numbers of trees that have been killed outright 

 with the kerosene used in those pumps. I don't want to run 

 down anybody's make of pumps, and I don't propose to do it. 

 and yet I must tell of the facts I know. By the way, I don't 

 know of any one that has killed trees with the lime-salt sulphur 

 mixture, and I do know of my own experience that one ap- 

 plication of sulphur mixture has actually freed certain trees of 

 the scale. I want to say a little about the K-L mixture that 

 perhaps is not known and might be known. As we get the 

 limoid, the commercial article, it is rather too gross; it also 

 carries with it a great deal of silica and it is very sharp, in- 

 deed, and cuts out the pistons of our pumps, and cuts the ori- 

 fice in our nozzles, so that perhaps a few days will entirely ruin 

 a pump and a set of nozzles. But if you will note in some 

 of the writings of scientists who have tested limoid, they will 

 say, use superfine limoid. Now that is a different article, as 

 I understand it, from the ordinary commercial article that 

 we use. The superfine is got in this way. Where the limoid 

 is ground, the dust that comes from that mill is wafted over 

 part way into the lumber and settles, and that constitutes super- 

 fine limoid, and the experiments that have been made by the 

 scientists, I understand from very good authority, are made 

 with that product. You can see that will give you much better 

 results than the domestic article that has been furnished to 

 the country at large. 



I might say a word about the making of a sulphur mixture. 

 and how I make my bordeaux. By the side of the building is 

 a tank, ten feet from the ground. That tank holds 450 gal- 

 lons, with three divisions in it. each division holding 150 gal- 

 lons. The main thing to know is exactly how much sulphur
